Increases durability by improving adhesion strength, compressive strength, and flexural strength of the reinforcing part to the parent body, improves freeze-thaw resistance and salt damage resistance to snow removal agents. It relates to a mortar composition for cross-section repair and reinforcement of road gutter concrete and road surface damage, and a construction method using the same.

일반적으로, 차량이 다니는 도로와 사람의 통행을 위한 보도는 아스팔트와 콘크리트로 포장되어 시공되는데, 도로와 보도 사이에는 배수로 등의 확보를 위해 측구가 설치되어 도로에 고인 물을 배수시킨다.In general, a road through which a vehicle travels and a sidewalk for the passage of people are paved with asphalt and concrete and constructed, and a gutter is installed between the road and the sidewalk to secure a drainage channel, etc. to drain water accumulated on the road.

이러한 도로 측구는 [도 1]에 도시한 바와 같이, 겨울철의 경우 결빙 및 융해 작용, 눈이 내릴 시 도로의 미끄럼 방지를 위해 도로 제설작업시 살포되는 습염, 제설제(염화칼슘)의 알칼리 골재반응에 의한 염해 등으로 인하여 노화되고 열화되는 현상이 발생하고, 시공 이후 시간이 지나면서 차량이 지나감에 따라 발생하는 하중, 진동 또는 온도변화에 의한 균열 및 파손이 발생하며, 보수보강 이후 보수보강 모르타르의 물성저하에 따른 2차 파손이 발생한다.As shown in [Fig. 1], these road gutters are used in the reaction of wet salt and snow removal agent (calcium chloride) to the alkali aggregate reaction of the wet salt and snow removal agent (calcium chloride) sprayed during snow removal to prevent the road from slipping when it snows and freezing and thawing in winter. Aging and deterioration occurs due to salt damage caused by Secondary damage occurs due to deterioration of physical properties.

또한, [도 2]에 도시한 바와 같이, 도로 노면은 싱크홀 발생, 중량 차량 또는 장마, 침수 등에 의하여 부분적으로 파손되는 문제점이 상존한다.In addition, as shown in [Fig. 2], there is a problem that the road surface is partially damaged due to sinkhole occurrence, heavy vehicle or rainy season, flooding, and the like.

상기와 같은 열화되거나 파손된 도로 측구는 주기적인 유지보수를 필요로 하는데, 종래에는 도로측구 또는 배수로를 포크레인 또는 브레이커로 파쇄한 후, 발생된 파쇄물을 제거하고 배수구 설치와 콘크리트 거푸집을 설치하여 콘크리트 타설 후 양생하여 보수하였으나, 이러한 방법은 양생 기간이 28일 정도로 너무 길어 교통 폐쇄에 대한 불편을 불러일으키며, 강도가 충분히 발휘되지 않고, 결빙, 융해 및 염해 등에 대한 저항성이 크지 않아 보수하더라도 또다시 재보수해야하는 문제점이 있었다.The deteriorated or damaged road gutter as described above requires periodic maintenance. Conventionally, after crushing the road gutter or drain with a fork crane or a breaker, the generated debris is removed, and concrete is poured by installing a drain hole and concrete formwork. After curing and repairing, this method causes inconvenience to traffic closure because the curing period is too long, about 28 days, and the strength is not sufficiently exhibited, and the resistance to freezing, thawing and salt damage is not great. There was a problem that had to be done.

또한, 부분적으로 파손된 도로 노면은 부분적으로 아스콘을 포설하여 보수하였으나, 노면의 레벨 맞춤이 미흡하여 노면 평탄도가 저하됨과 동시에 아스콘의 부착이 저하되어 탈리되거나 2차 파손되는 문제점이 있었다.In addition, the partially damaged road surface was repaired by partially installing asphalt concrete, but due to insufficient level alignment of the road surface, the flatness of the road surface was lowered, and at the same time, there was a problem of detachment or secondary damage due to the deterioration of the asphalt adhesion.

이에 따라, 상기와 같은 종래 문제점을 해결하기 위하여 도로 측구 콘크리트 및 도로 노면 파손부의 단면보수보강용 모르타르 조성물을 이용한 시공방법이 개발되었는데, 한국등록특허 10-1023015(등록일자 2011년03월10일)에 도로측구가 일정 깊이로 파쇄되어 파쇄부가 형성되는 단계; 상기 도로측구가 파쇄된 후, 상기 파쇄부에 폴리머 3-5중량%와, 알루미늄 분말 4-6 중량%와, 시멘트 35-40중량%와, 규사 45-50중량%와, 실리카퓸 2-4중량%, 혼화재 1-3중량%의 비율로 이루어진 프리믹스 타입 모르타르를 포설하는 단계; 그리고 상기 프리믹스 타입 모르타르가 양생되는 단계를 포함하는 도로측구 보수방법이 개발되었다.Accordingly, in order to solve the conventional problems as described above, a construction method using road gutter concrete and a mortar composition for cross-section repair and reinforcement of damaged parts of the road was developed. The step of forming a crushed portion by crushing the road side guiding to a predetermined depth; After the road gutter is crushed, 3-5% by weight of polymer, 4-6% by weight of aluminum powder, 35-40% by weight of cement, 45-50% by weight of silica sand, and 2-4 by weight of silica fume in the crushed part Laying a premix type mortar consisting of a weight%, 1-3% by weight of the admixture; And a road gutter repair method including the step of curing the premix type mortar has been developed.

그러나, 상기 프리믹스 타입 모르타르는 동결융해에 대한 저항성은 나타내고 있지만, 제설제에 대한 염해 저항성이 미흡하여 겨울철 마다 염해에 의하여 균열, 파손되어 매년 재보수해야하는 치명적인 문제점이 있었다.However, although the premix type mortar shows resistance to freezing and thawing, salt damage resistance to the snow removal agent is insufficient, so there is a fatal problem that it is cracked and damaged by salt damage every winter, and needs to be repaired every year.

이하에서는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 용이하게 실시할 수 있도록 본 발명의 실시예 및/또는 도면을 통하여 상세히 설명한다. 그러나 본 발명은 여러 가지 상이한 형태로 구현될 수 있으며, 여기에서 설명하는 실시예 및/또는 도면에 한정되지 않는다.Hereinafter, embodiments and/or drawings of the present invention will be described in detail so that those of ordinary skill in the art can easily carry out the present invention. However, the present invention may be embodied in many different forms, and is not limited to the embodiments and/or drawings described herein.

우선, 본 발명의 도로 측구 콘크리트 및 도로 노면 파손부의 단면보수보강용 모르타르 조성물은, OPC(Ordinary Portland Cement) 50-100중량부, CSA(Calcium Sulfo Aluminate ; 3CaO·3Al2O3·CaSO4) 0.5-10중량부, 석고 0.5-10중량부, 실리카흄 0.1-5중량부, 나노탄산칼슘 0.5-5중량부, 5호사 및 6호사의 혼합규사 40-65중량부, MMA모노머액상수지 및 VAE재유화형분말수지의 혼합수지 5-15중량부, 보강섬유 2~5중량부, 유동화제 0.1-1.0중량부, 증점제 0.05-5중량부, 경화촉진제 0.05-0.5중량부, 지연제 0.1-0.4중량부, 소포제 0.05-3중량부 및 물을 포함하여 조성된다.First, the mortar composition for cross-section repair and reinforcement of road guttering concrete and road surface damage of the present invention is OPC (Ordinary Portland Cement) 50-100 parts by weight, CSA (Calcium Sulfo Aluminate; 3CaO·3Al 2 O 3 ·CaSO 4 ) 0.5 -10 parts by weight, 0.5-10 parts by weight of gypsum, 0.1-5 parts by weight of silica fume, 0.5-5 parts by weight of nano calcium carbonate, 40-65 parts by weight of mixed silica sand of No. 5 and No. 6, MMA monomer liquid resin and VAE re-emulsification type Powder resin mixed resin 5-15 parts by weight, reinforcing fibers 2-5 parts by weight, fluidizing agent 0.1-1.0 parts by weight, thickener 0.05-5 parts by weight, curing accelerator 0.05-0.5 parts by weight, retarder 0.1-0.4 parts by weight, It is formulated to contain 0.05-3 parts by weight of an antifoaming agent and water.

여기서, 상기 OPC(Ordinary Portland Cement)는 주성분인 석회, 실리카, 알루미나 및 산화철을 함유하는 원료를 적당한 비율로 충분히 혼합하고, 그 일부가 용융하여 소결된 클링커에 석고를 첨가해 분말로 한 것이며, 오늘날 쓰이고 있는 보통 시멘트 형태이며, 전 세계적으로 콘크리트, 모르타르, 그라우트 등의 기본 재료로 널리 쓰인다Here, the OPC (Ordinary Portland Cement) is obtained by mixing raw materials containing lime, silica, alumina and iron oxide, which are main components, in an appropriate ratio, and adding gypsum to the clinker that is partially melted and sintered to make a powder. It is a common cement type used and is widely used worldwide as a basic material for concrete, mortar, grout, etc.

또한, 상기 CSA(Calcium Sulfo Aluminate ; 3CaO·3Al2O3·CaSO4)는 수축보상, 고강도, 예를 들면 높은 압축강도와 휨강도 및 초속경을 부여하기 위한 물질로서, 수화하여 에트링자이트(ettringite)를 생성한다. 상기 CSA(Calcium Sulfo Aluminate)는 비표면적이 4,000 내지 8,000㎠/g 인 것이 바람직하며, 본 발명에 따른 모르타르 조성물에 0.5-10중량부 사용하는 것이 바람직하며, 10중량부 초과하면 너무 속경성을 나타내어 가사시간이 짧아 작업성이 저하된다.In addition, the CSA (Calcium Sulfo Aluminate; 3CaO·3Al 2 O 3 ·CaSO 4 ) is a material for imparting shrinkage compensation, high strength, for example, high compressive strength, flexural strength and initial velocity, and hydrated ettringite ( ettringite). The CSA (Calcium Sulfo Aluminate) preferably has a specific surface area of 4,000 to 8,000 cm2/g, and is preferably used in 0.5-10 parts by weight in the mortar composition according to the present invention, and when it exceeds 10 parts by weight, it exhibits too fast setting. Working time is reduced due to short pot life.

상기 석고는 상기 OPC(Ordinary Portland Cement) 및 CSA(Calcium Sulfo Aluminate)의 응결지연제로 사용되어 본 발명의 모르타르 조성물의 장기강도를 나타내도록 함과 동시에 조직을 치밀하게 하여 콘크리트의 균열을 방지하고 콘크리트의 수축을 방지할 수 있는 효과가 있으며, 그 자체가 안정한 황산염이므로 황산염저항성을 나타낸다.The gypsum is used as a setting retardant of the OPC (Ordinary Portland Cement) and CSA (Calcium Sulfo Aluminate) to exhibit the long-term strength of the mortar composition of the present invention, and at the same time to make the structure dense to prevent cracking of concrete and It has the effect of preventing shrinkage, and since it is a stable sulfate itself, it exhibits sulfate resistance.

상기 실리카흄 및 나노탄산칼슘은 본 발명의 모르타르 조성물의 동결융해 및 내구성을 향상시키고, 균열 저항성을 가지도록 하기 위한 것으로, 상기 실리카흄(silica fume)은 비정질의 활성 실리카로서 평균입경이 0.15㎛ 정도이며, 완전 구형에 가까운 입자이다. 상기 실리카흄은 구상입자의 특성에 의해 결합제 입자 사이의 충진 효과에 의하여 방수성 및 내화학성을 향상시키며, 보수 보강제의 강도를 향상시키는 역할을 한다. 특히, 실리카흄은 보수 보강제의 부착성능을 향상시키는 역할을 하기도 한다. The silica fume and nano calcium carbonate are to improve the freeze-thaw and durability of the mortar composition of the present invention and to have crack resistance. It is a particle close to a perfectly spherical shape. The silica fume improves waterproofness and chemical resistance by the filling effect between the binder particles due to the characteristics of the spherical particles, and serves to improve the strength of the repair and reinforcing agent. In particular, silica fume also plays a role in improving the adhesion performance of the repair and reinforcing agent.

또한, 상기 나노탄산칼슘은 본 발명의 모르타르 조성물의 조직 및 표면을 치밀하게 하여 동결융해저항성 및 균열저항성을 향상시킨다. 특히, 상기 나노탄산칼슘은 분쇄형 나노탄산칼슘 또는 침강형 나노탄산칼슘을 사용할 수 있으며, 상기 나노 탄산칼슘은 평균 입자크기는 100 ~ 10000 nm가 바람직하다. 100 nm 미만인 경우에는 다른 성분과 혼합성이 떨어지고, 혼합 시 교반이 잘되지 않아서 제조 공정에 문제점이 발생하고, 10000 nm 초과인 경우에는 동결융해저항성 및 균열저항성이 저하될 우려가 있다.In addition, the nano calcium carbonate improves the freeze-thaw resistance and crack resistance by making the structure and surface of the mortar composition of the present invention dense. In particular, as the nano calcium carbonate, pulverized nano calcium carbonate or precipitated nano calcium carbonate may be used, and the average particle size of the nano calcium carbonate is preferably 100 to 10000 nm. If it is less than 100 nm, miscibility with other components is poor, and the stirring is not good when mixing, which causes a problem in the manufacturing process.

상기 실리카흄 및 나노탄산칼슘은 본 발명의 모르타르 조성물에 각각 0.1-5중량부 및 0.5-5중량부 사용하는 것이 바람직하며, 상기 범위를 벗어나는 경우에는 물성저하 또는 불필요한 재료사용에 따라 비용이 상승된다.The silica fume and nano calcium carbonate are preferably used in 0.1-5 parts by weight and 0.5-5 parts by weight, respectively, in the mortar composition of the present invention.

상기 혼합규사는 5호사(1.6-0.8mm) 및 6호사(0.8-0.3mm)의 혼합규사를 사용하며, 이때, 상기와 같이 혼합규사를 사용하게 되면 6호사(0.8-0.3mm)의 다소 굵은 골재의 작용으로 인해 기계적 강도 및 내구성을 향상시킬 수 있다.The mixed silica sand uses a mixture of No. 5 sand (1.6-0.8 mm) and No. 6 sand (0.8-0.3 mm), and at this time, when the mixed silica sand is used as described above, it is somewhat coarser than the No. 6 sand (0.8-0.3 mm). Mechanical strength and durability can be improved due to the action of aggregates.

상기 MMA모노머액상수지 및 VAE재유화형분말수지는 본 발명의 모르타르 조성물에 혼합사용되어 OPC(Ordinary Portland Cement), CSA(Calcium Sulfo Aluminate) 및 잔골재 사이에 바인더 역할를 해주어 접착강도 증가, 내마모성 향상, 크랙 및 박리현상 방지, 휨강도를 강화시켜 줄 뿐만 아니라, 조직의 치밀화로 인한 동경융해 및 염해저항성도 향상시키는 효과가 있다.The MMA monomer liquid resin and VAE re-emulsifiable powder resin are mixed and used in the mortar composition of the present invention to serve as a binder between OPC (Ordinary Portland Cement), CSA (Calcium Sulfo Aluminate) and fine aggregate to increase adhesive strength, improve abrasion resistance, crack and Not only does it prevent delamination and strengthen the flexural strength, but it also has the effect of improving resistance to Tokyo melting and salt damage due to tissue densification.

특히, 상기 MMA(methyl methacrylate)모노머액상수지는 무색투명한 액체로서 저온에서 라티칼 중합하면 고분자 사슬 구조를 이루어 무기골재 사이의 바인더 역할을 하며, 상기 VAE재유화형분말수지는 두 종류의 단량체로 구성된 코폴리머(Copolymer) 분말수지이며, 콘크리트에 VAE 분말수지를 결합재로 사용할 경우 휨, 인장 강도 등이 증가할 뿐만 아니라, 콘크리트의 내구성이 향상된다.In particular, the MMA (methyl methacrylate) monomer liquid resin is a colorless and transparent liquid, and when radically polymerized at a low temperature, it forms a polymer chain structure and serves as a binder between inorganic aggregates. It is a polymer powder resin, and when VAE powder resin is used as a binder in concrete, bending and tensile strength are increased as well as durability of concrete is improved.

이때, 상기 MMA(methyl methacrylate)모노머액상수지 및 VAE재유화형분말수지는 동일중량비로 5~15중량부 사용하는 것이 바람직하며, 사용량이 5중량부 미만이면 기대 이상의 접착력, 내마모성, 휨강도 등의 물리적 물성이 나오지 않고, 15중량부를 초과하면 경화가 지연되고 모르타르의 압축강도가 떨어지는 단점이 있다. At this time, it is preferable to use 5 to 15 parts by weight of the MMA (methyl methacrylate) monomer liquid resin and VAE re-emulsifiable powder resin in the same weight ratio. This does not come out, and if it exceeds 15 parts by weight, hardening is delayed and the compressive strength of the mortar is lowered.

상기 보강섬유는 모르타르 조성물의 건조수축 및 균열예방을 위한 것으로 0.5-10mm길이의 강섬유, 탄소섬유, 유리섬유, 나일론섬유, 폴리프로필렌섬유, PVA섬유, 셀룰로오스섬유, PET섬유 및 이들의 혼합 섬유로 이루어진 군에서 선택되는 1종 이상인 것을 사용하며, 이때, 그 사용량은 2~5중량부 사용하는 것이 좋다The reinforcing fibers are for preventing drying shrinkage and cracking of the mortar composition, and are made of 0.5-10 mm long steel fibers, carbon fibers, glass fibers, nylon fibers, polypropylene fibers, PVA fibers, cellulose fibers, PET fibers, and mixed fibers thereof. At least one selected from the group is used, and in this case, it is recommended to use 2 to 5 parts by weight of the amount.

본 발명에서, 첨가제로 사용되는 유동화제는 나프탈렌계, 멜라민계, 폴리카르본산계 등의 유동화제를 사용할 수 있다. 이때, 본 발명에서 상기 유동화제는 0.1-1.0중량부 범위로 포함되는 것이 바람직한데, 상기 함량이 0.1 중량부 미만이면 점도를 떨어뜨리는 효과를 발휘할 수 없고, 1.0 중량부를 초과할 경우에는 재료분리, 블리딩 발생 등의 문제점들이 발생할 수 있다In the present invention, the fluidizing agent used as an additive may be a fluidizing agent such as naphthalene, melamine, or polycarboxylic acid. At this time, in the present invention, the fluidizing agent is preferably included in the range of 0.1-1.0 parts by weight. If the content is less than 0.1 parts by weight, the effect of lowering the viscosity cannot be exhibited, and when it exceeds 1.0 parts by weight, material separation, Problems such as bleeding may occur

또한, 상기 증점제는 본 발명의 모르타르 조성물의 점도를 증가시켜 작업성을 향상시키며, 부착성 및 강도보강을 위한 것으로, 구체적으로는 셀룰로오스계 증점제를 사용할 수 있다. 상기 증점제는 본 발명의 모르타르 조성물중 0.05-5중량부로 포함될 수 있으며, 만약 약 0.05 중량부 미만일 경우 분리 현상이 발생할 수 있고, 약 5 중량부를 초과할 경우 응집이 과도하게 일어나 품질이 저하될 수 있다.In addition, the thickener increases the viscosity of the mortar composition of the present invention to improve workability, and is intended to enhance adhesion and strength, and specifically, a cellulose-based thickener may be used. The thickener may be included in an amount of 0.05-5 parts by weight in the mortar composition of the present invention. If it is less than about 0.05 parts by weight, separation may occur, and if it exceeds about 5 parts by weight, aggregation may occur excessively and the quality may be deteriorated. .

또한, 상기 경화촉진제는 본 발명의 모르타르 조성물의 경화를 촉진시키기 위해 사용되는 것으로, BPO(벤질퍼옥사이드)의 과산화물, CaCl2, Na2CO3, Al(OH)3, NaAlO2 등의 염화물이나 알카리 탄산염, 알카리 알루민산염 등의 무기계 경화촉진제가 사용될 수 있으며, 상기 경화촉진제는 지연제와 함께 사용되어 작업 시간을 조절할 수 있고, 이때, BPO 및 NaAlO2가 바람직하며, 본 발명의 모르타르 조성물중 0.05-0.5중량부 범위로 포함되는 것이 바람직하다.In addition, the curing accelerator is used to accelerate the curing of the mortar composition of the present invention, peroxide of BPO (benzyl peroxide), CaCl 2 , Na 2 CO 3 , Al(OH) 3 , NaAlO 2 Chlorides such as Inorganic curing accelerators such as alkali carbonate and alkali aluminate may be used, and the curing accelerator may be used together with a retarder to control the working time, in this case, BPO and NaAlO 2 are preferred, and in the mortar composition of the present invention It is preferably included in the range of 0.05-0.5 parts by weight.

또한, 상기 지연제는 본 발명의 모르타르 조성물이 굳는 현상을 지연시킴으로써 작업성을 향상시키는 것으로, 예를들어, 주석산, 글루콘산, 구연산, 옥시카본산 등이 사용될 수 있다. 상기 지연제는 본 발명에서 0.1-0.4중량부 포함될 수 있으며, 만약 0.1 중량부 미만일 경우 시멘트 경화 시간이 지나치게 빨라져 작업성이 하락할 수 있고, 0.4 중량부를 초과할 경우 양생에 많은 시간이 소요될 수 있다.In addition, the retarder improves workability by delaying the solidification of the mortar composition of the present invention, and for example, tartaric acid, gluconic acid, citric acid, oxycarboxylic acid and the like may be used. The retarder may be included in 0.1-0.4 parts by weight in the present invention, and if it is less than 0.1 parts by weight, the cement hardening time may be too fast and workability may decrease, and if it exceeds 0.4 parts by weight, it may take a lot of time for curing.

한편, 본 발명의 상기 모르타르 조성물은 상기 OPC(Ordinary Portland Cement) 사용량의 5~10중량%의 가넷폐분말을 추가 혼합 사용하여 천연골재자원을 절약할 수 있다.On the other hand, the mortar composition of the present invention can save natural aggregate resources by additionally mixing and using 5 to 10% by weight of garnet waste powder of the OPC (Ordinary Portland Cement) usage.

즉, 가넷은 규산염광물로서 다양한 성분으로 구성되고 규사를 포함하는 잔골재보다 높은 비중 3.4~3.9g/cm, 모스(MOHS)경도 6.0~8.0을 나타내므로 샌드블라스팅 등의 연마재용으로 사용되거나, 또는 워터젯 커팅용으로 사용되므로, 본 발명에서는 상기 가넷의 높은 경도 및 비중에 의한 모르타르의 강도를 향상시키기 위하여 연마재용 가넷슬러지 또는 워터젯 커팅용 가넷슬러지로부터 회수되는 입자크기 0.05~1mm의 가넷폐분말을 혼합 사용하여 강도를 보강함과 동시에 천연골재자원을 절약한다.That is, garnet is a silicate mineral, composed of various components, and has a specific gravity of 3.4 to 3.9 g/cm and a Mohs (MOHS) hardness of 6.0 to 8.0, which is higher than that of fine aggregates containing silica sand. Because it is used for cutting, in the present invention, in order to improve the strength of the mortar due to the high hardness and specific gravity of the garnet, waste garnet powder having a particle size of 0.05 to 1 mm recovered from garnet sludge for abrasive or waterjet cutting is mixed and used. This enhances strength and saves natural aggregate resources.

뿐만 아니라, 상기 모르타르 조성물은 상기 혼합규사의 10~30중량%를 페로니켈슬래그잔골재 및/또는 폐유리잔골재로 대체 사용하여 천연골재자원을 절약할 수 있다.In addition, the mortar composition can save natural aggregate resources by replacing 10 to 30% by weight of the mixed silica sand with ferronickel slag fine aggregate and/or waste glass fine aggregate.

이때, 상기 페로니켈 슬래그는 제강 슬래그처럼 팽창에 문제가 되는 프리 석회 및 마그네슘이 존재하지 않아 팽창에 대한 안정성이 있는 것으로 보고되고 있으며, 특히 입자별로 규사 5, 6호사, 즉 1.2-2.5mm는 연마사로 많이 사용되고 있는데, 이는 페로니켈 슬래그가 일반 슬래그에 비해 높은 경도를 가지고 있어 연마사로 사용이 가능한 것이고, 또한 일반 골재와 비슷한 밀도인 2.9-3.1의 가지고 있어 제강 슬래그에 비해 비중이 낮아 재료 분리가 일어나지 않으므로 콘크리트용 잔골재로 사용이 가능하다.At this time, the ferronickel slag is reported to have stability against expansion because free lime and magnesium, which are problematic for expansion, do not exist like steelmaking slag. It is widely used as sand, which is because ferronickel slag has a higher hardness than general slag, so it can be used as abrasive sand. Also, it has a density of 2.9-3.1, similar to that of general aggregate, so it has a low specific gravity compared to steelmaking slag, so material separation does not occur. Therefore, it can be used as a fine aggregate for concrete.

또한, 상기 폐유리잔골재는 유리섬유시트 제조공정중 절단공정에서 발생하는 유리섬유시트를 분쇄한 것으로 일자(-)구조를 가지는 유리섬유는 모르타르를 보강하는 효과가 있으나 격자구조를 가지는 폐유리분말 보다 1.2-1.4% 정도 인장 강도 저하가 발생되는 것으로 나타나므로 본 발명에서는 유리섬유시트 제조공정중 절단공정에서 발생하는 유리섬유시트를 분쇄한 격자구조를 가지는 폐유리분말을 폐유리잔골재로 활용한다.In addition, the fine waste glass aggregate is a pulverized glass fiber sheet generated in the cutting process during the glass fiber sheet manufacturing process, and the glass fiber having a straight (-) structure has an effect of reinforcing the mortar, but it is better than the waste glass powder having a lattice structure. Since it appears that a decrease in tensile strength of about 1.2-1.4% occurs, in the present invention, a waste glass powder having a lattice structure obtained by crushing a glass fiber sheet generated in a cutting process during a glass fiber sheet manufacturing process is used as a fine waste glass aggregate.

본 발명의 또다른 측면으로서, 상기 모르타르 조성물은 상기 OPC(Ordinary Portland Cement)와 혼합 경화시 치밀한 조직으로 경화되어 염화물이온을 고정하는 프리델씨염(3CaO·Al2O3·CaCl2·10H20) 수화물을 생성하여 염해저항성을 나타내는 고로슬래그분말을 상기 OPC(Ordinary Portland Cement) 사용량의 5~10중량%로 추가 혼합 사용하는 것을 특징으로 하며, 이 경우 모르타르 조성물의 염해저항성이 매우 크게 증대되므로 겨울철 제설제 등의 염해를 방지하게 된다.As another aspect of the present invention, the mortar composition is cured into a dense structure when mixed and cured with the OPC (Ordinary Portland Cement) to fix the chloride ions (3CaO·Al 2 O 3 ·CaCl 2 ·10H 2 0). ) It is characterized in that the blast furnace slag powder, which produces hydrates and exhibits salt damage resistance, is additionally mixed and used at 5 to 10 wt% of the OPC (Ordinary Portland Cement) usage. In this case, the salt damage resistance of the mortar composition is greatly increased, so It prevents salt damage such as snow removal agents.

이때, 상기 고로슬래그분말은, 잠재수경성을 가지고 있으며, 그 자체로 경화하는 성질은 미약하지만, OPC(Ordinary Portland Cement)와 혼합할 경우 수산화칼슘이나 황산염의 작용에 의해 경화가 촉진되고 시멘트만으로는 얻을 수 없는 우수한 콘크리트의 특성을 얻을 수 있다. At this time, the blast furnace slag powder has latent hydraulic properties and has a weak hardening property by itself, but when mixed with OPC (Ordinary Portland Cement), hardening is promoted by the action of calcium hydroxide or sulfate, and it cannot be obtained with cement alone. Excellent concrete properties can be obtained.

여기서, 고로슬래그분말의 잠재수경성은 수산화기를 포함하는 알칼리시제가 소석회, 황산염 등의 자극을 받으면 박막이 파괴되며 이온이 용출됨에 따라 경화되는 특징을 의미한다.Here, the latent hydraulicity of the blast furnace slag powder means that the thin film is destroyed when an alkali reagent containing a hydroxyl group is stimulated by slaked lime, sulfate, etc., and is hardened as ions are eluted.

특히, 일반적으로 상기 고로슬래그분말의 전체 성분 중 약 30중량%가 이산화규소로 구성되며, OPC(Ordinary Portland Cement)와 비교하여 산화칼슘의 함유량이 상대적으로 적고, 이산화규소 및 산화알루미늄이 각각 약 10중량% 정도 더 함유됨에 따라, 상기 고로슬래그분말이 OPC(Ordinary Portland Cement)와 혼합 경화시 치밀한 조직으로 경화되어 염화물이온의 침투를 억제하며, 산화알루미늄 성분이 작용하여 염화물이온을 고정하는 프리델씨염(3CaO·Al2O3·CaCl2·10H20) 수화물을 생성하여 염해저항성을 향상시킨다.In particular, in general, about 30% by weight of the total component of the blast furnace slag powder is composed of silicon dioxide, the content of calcium oxide is relatively small compared to OPC (Ordinary Portland Cement), and silicon dioxide and aluminum oxide are each about 10 Friedel's salt, which contains about % by weight more, the blast furnace slag powder is hardened into a dense structure when mixed with OPC (Ordinary Portland Cement) and hardened to suppress the penetration of chloride ions, and the aluminum oxide component acts to fix the chloride ions (3CaO·Al 2 O 3 ·CaCl 2 ·10H 2 0) Forms hydrate to improve resistance to salt damage.

아울러, 선택적으로, 상기 염해저항성을 나타내는 고로슬래그분말에는 염해저항성 보조재로서 규산나트륨분말, 질산나트륨분말 및 황산알루미늄분말이 1 : 1 : 1 중량비로 혼합된 분말을 상기 고로슬래그분말 100중량부에 대하여 0.5~20중량부 혼합사용하여 염해저항성을 증대시킬 수 있다.In addition, optionally, in the blast furnace slag powder exhibiting salt damage resistance, sodium silicate powder, sodium nitrate powder and aluminum sulfate powder as a salt damage resistance auxiliary material are mixed in a 1:1 weight ratio with respect to 100 parts by weight of the blast furnace slag powder. Salt damage resistance can be increased by mixing 0.5 to 20 parts by weight.

이때, 상기 규산나트륨분말은 OPC(Ordinary Portland Cement)와 혼합되어 수경성 경화시 콘크리트의 표면 경화조직의 치밀화에 의해 외부 열화요인에 대한 저항성을 확보하고 장기 압축강도를 증진하며, 일반 콘크리트에 비해 초기 재령 강도는 낮으나 실리카의 포졸란 작용에 의해 재령 28일 이후 장기강도가 증진된다.At this time, the sodium silicate powder is mixed with OPC (Ordinary Portland Cement) to secure resistance to external deterioration factors by densification of the surface hardened tissue of concrete during hydraulic hardening, and to enhance long-term compressive strength, and to increase the initial age compared to general concrete Although the strength is low, the long-term strength is improved after 28 days of age by the pozzolanic action of silica.

또한, 상기 질산나트륨분말과 황산알루미늄분말은 OPC(Ordinary Portland Cement)와 혼합되어 수경성 경화시 염소이온 고정화, 응집화 및 방청효과에 의해 염소이온의 침투저항성을 향상시키고, 콘크리트에 배근된 철근의 부식 억제제로서 작용하여 염해저항성을 나타낸다.
