본 발명은 가용성 특수 규산염을 함유하는 흙콘크리트 조성물과 이를 이용한 표면강화형 흙포장공법에 관한 것으로, 가용성 특수 규산염을 함유하는 무시멘트 첨가형 흙콘크리트 조성물에 의해 흙포장층을 시공하고, 상기 흙포장층에 분말형 표면마감재를 도포하여 흙의 고유성질을 유지하면서 소정시간 내에 유효강도를 발휘할 수 있는 가용성 특수 규산염을 함유하는 흙콘크리트 조성물과 이를 이용한 표면강화형 흙포장공법에 관한 것이다.
The present invention relates to a soil concrete composition containing a soluble special silicate and a surface-reinforced soil packaging method using the same, and constructing the soil packing layer by a cement-added soil concrete composition containing a soluble special silicate, the soil packaging layer The present invention relates to a soil concrete composition containing a soluble special silicate capable of exerting effective strength within a predetermined time while maintaining a unique property of the soil by applying a powder-type surface finish to it, and a surface-enhanced soil packaging method using the same.

일반적으로 도로포장은 도로면을 보호 강화하고 평탄성을 높여 사람의 통행과 차량의 주행을 편하게 하기 위하여 처리된 노면구조물로서, 여러 층으로 이루어진 층구조이며, 표층부의 재질에 따라 역청계(아스팔트) 포장, 콘크리트계 포장 및 블록 포장으로 크게 분류된다. In general, road pavement is a road structure that is treated to enhance the protection and flatness of the road surface and to facilitate the passage of people and the driving of vehicles. It is a multi-layered layer structure. , Concrete-based pavement and block pavement.

근래에 들어 세계적으로 친환경 즉, 녹색산업이 주를 이루고 있으며 이는 건축분야에도 영향을 주어 도시사막화의 주범이 되는 아스팔트, 시멘트를 대체하여, 환경 친화적이면서도 인체에 해를 끼치지 않는 흙을 이용한 포장공법이 도로, 공원, 운동장, 산책로, 보도 등의 조성에 널리 사용되고 있다. In recent years, eco-friendly, or green industry, has become a major factor in the world, and this is a paving method that uses environmentally friendly and non-harmful soil, replacing asphalt and cement, which are the main culprit of urban desertification, affecting the construction field. It is widely used in the construction of roads, parks, sports grounds, walkways and sidewalks.

상기 흙을 이용한 흙 포장공법은 기존의 골재 등을 이용한 아스팔트 콘크리트와 콘크리트 포장과는 달리 화강풍화토 등의 주변의 토사에 시멘트 또는 고화제 등을 이용하는 포장으로, 흙 포장은 비교적 하중이 적게 작용하는 자전거 도로, 주차장, 주택단지내의 도로, 농로, 산책로, 공원광장 등에 적용되고 있으며, 흙 포장의 주요재료는 포틀란트 시멘트를 주로 하여, 각종 첨가제가 사용한다.
The soil pavement method using the soil is a pavement using cement or hardener in the surrounding soil such as granite weathering soil, unlike asphalt concrete and concrete pavement using the existing aggregates, dirt pavement bike with relatively less load It is applied to roads, parking lots, roads in residential complexes, farm roads, trails, park plazas, etc. The main material of soil pavement is mainly made of portland cement, and various additives are used.

종래에 사용되고 있는 흙포장 공법은 습식과 건식 두가지로 나뉘어 시공되고 있으며, 상기 습식 포장공법은 시멘트를 이용한 고화재와 혹은 일반시멘트를 사용하여 일반 콘크리트 배합에 일부 마사토 혹은 황토를 혼합하여 시공되며 시공이 편리하고 흙콘크리트 조성물 생산 또한 레미콘 플랜트를 이용함으로써 효율성이 좋으나 시멘트를 다량 사용하여 환경성이 문제가 될 수 있으며 표면 강도가 낮아 차량 통행이나 동결융해 저항성이 아주 낮아 그 문제가 야기되고 있다. 또한, 건식 포장공법은 무흐름성 배합물을 현장에서 배합하여 사용함으로 강도가 높고, 내구성도 좋은 편이지만 현장혼합, 이송, 타설 시공하여야 하는 문제로 시공성이 나쁘고, 인력 포설로 인하여 시공비용이 높고, 표면의 겉마름으로 인하여 표면강도가 낮아 2차 표면강화제를 포설하는 등 시공 후에 2차 처리하고 있는 실정이다.The conventional earth paving method is used to be divided into two types of wet and dry, and the wet paving method is constructed by mixing some Masato or ocher in a general concrete mixture using solid materials using cement or general cement. It is convenient and the production of soil concrete composition is also good efficiency by using a ready-mixed concrete plant, but the environmental problems can be a problem by using a large amount of cement, and the surface strength is low, the resistance to vehicle traffic or freeze-thawing is very low, causing the problem. In addition, the dry packaging method has high strength and good durability by blending flow-free formulations in the field, but has poor construction properties due to the problem of on-site mixing, conveying and placing, and high construction cost due to manpower installation. Due to the surface dryness, the surface strength is low, and the secondary treatment is performed after the construction such as laying a second surface hardener.

특히, 흙포장 시공방법에 사용되는 흙은 매우 다양한 성분을 함유하고 있는 비교적 작은 덩어리의 형태로 결속력이 현저히 떨어지는 재료이므로 이를 그대로 흙포장에 사용하기가 어려운 문제점이 있었다. In particular, the soil used in the earth paving method has a problem that it is difficult to use it in the earth paving because it is a material that falls significantly in the form of a relatively small lump containing a variety of components.

이와 같은 연유로 인하여, 종래의 흙을 이용한 포장공법에는 적은 비용으로 흙을 고화시킬 수 있고 사용이 간단하기 때문에 흙을 고화시키는 결합재로 포틀랜트 시멘트, 슬래그 시멘트, 플라이애시 시멘트 등의 시멘트류가 널리 사용되고 있다. Due to this condensed milk, cements such as portland cement, slag cement, fly ash cement, etc. are widely used as binders to solidify the soil, since the soil can be solidified at a low cost and simple to use. It is used.

그러나 이러한 시멘트류는 동결 융해에 의한 내구성 저하, 건조수축에 의해 균열이 발생되고, 중금속이 용출될 위험성이 있으며, 상기 시멘트의 생산으로 인하여 막대한 CO2 가스가 발생되므로, 환경오염 및 대기오염을 일으키는 문제점이 있었다. However, such cements have a risk of cracking due to deterioration in durability due to freeze-thawing, drying shrinkage, heavy metals eluting, and enormous CO 2 gas generated by the production of the cement, causing environmental pollution and air pollution. There was a problem.

물론, 시멘트를 사용하지 않는 흙포장 공법에 대한 다양한 연구가 진행되고 있으나, 종래의 흙포장 공법은 환경보전 측면에서 상당한 효과가 있기는 하나, 흙 자체 점성 또는 부착력이 약해서 일정한 형태로 성형하기 어렵고, 강도 및 경도가 약하여 사용 중 깨지거나 크랙이 발생될 뿐 아니라, 물에 잘 풀리고, 시간이 지날수록 강도가 약해지는 단점이 있어서 도로용으로 활용하기에 적합하지 않은 제약이 있는 등 여러가지 문제점이 있었다.
Of course, various studies have been conducted on the soil pavement method without using cement, but the conventional soil pavement method has a considerable effect in terms of environmental conservation, but it is difficult to mold to a constant shape due to its weak viscosity or adhesion. The strength and hardness is weak, so that not only cracking or cracking occurs during use, but also loosens well in water, has a disadvantage of weakening strength over time, there are various problems such as there is a restriction that is not suitable for use for roads.

본 발명에 따른 흙콘크리트 조성물은 흙배합물 100 중량부에 대하여, 경화제 4∼10 중량부로 이루어지고, 상기 흙배합물은 고로수쇄 슬래그 5∼20중량%, 플라이애쉬 5∼15중량%, 마사토 10∼30중량%, 황산알루미늄(AL2SO4) 0.1∼0.5중량%, 콘크리트용 골재 35∼60중량% 를 포함하며, 상기 경화제는 가용성 특수 규산염과 물이 1 : 1 의 중량비로 배합되어 있다.The soil concrete composition according to the present invention is composed of 4 to 10 parts by weight of a curing agent based on 100 parts by weight of the soil mixture, the soil mixture is 5 to 20% by weight of blast furnace slag, 5 to 15% by weight of fly ash, Masato 10 to 30 Wt%, aluminum sulfate (AL2SO4) 0.1 to 0.5% by weight, concrete aggregate 35 to 60% by weight, wherein the curing agent is a soluble special silicate and water in a weight ratio of 1: 1.

상기 고로수쇄 슬래그는 분말도 4000㎠/g 이상의 것을 사용하고, 잠재수경성 재료로써 강도를 증진시키고 황산알루미늄의 첨가에 의해 시멘트 이상의 강도를 발현한다. 상기 고로수쇄 슬래그는 5중량% 미만으로 첨가될 시에는 강도증진 효과가 크지 않으며, 20중량%를 초과하여 첨가될 경우, 슬래그의 잠재 수경성으로 초기 경화속도가 지연되고, 중금속 등의 고착화 및 안정화 효과가 감소될 뿐 아니라, 다른성분들의 첨가량에 영향을 주므로, 상기 범위내에서 첨가되어야 한다. The blast furnace chain slag uses a powder degree of 4000 cm 2 / g or more, and enhances the strength as a latent hydraulic material and expresses the strength of cement or more by the addition of aluminum sulfate. When the blast furnace chain slag is added in less than 5% by weight, the strength-improving effect is not great, and when it is added in excess of 20% by weight, the initial curing rate is delayed due to the latent hydraulic properties of the slag, and the solidification and stabilizing effect of heavy metals and the like. Not only decreases, but also affects the addition amount of the other components, so it should be added within the above range.

상기 플라이 애쉬는 고로수쇄 슬래그의 알루미나 소스를 제공하여 에트링자이트를 생성하며, KS F 콘크리트용 플라이 애쉬 규정을 준수하는 제품을 사용한다. The fly ash provides an alumina source of blast furnace slag to produce ettringite, and uses a product that complies with the fly ash regulations for KS F concrete.

상기 마사토는 5㎜ 이하의 마사토를 이용하여야 하며, 함수율이 20%를 넘지 않아야 한다. 상기 마사토는 10중량% 미만으로 첨가될 시에는 흙의 기본성질이 표현되기 곤란하고, 30중량%를 초과하여 첨가시에는 강도가 저하되는 현상이 발생된다.Masato must be 5 mm or less in size, and the water content should not exceed 20%. When the masato is added in less than 10% by weight, it is difficult to express the basic properties of the soil, and when added in excess of 30% by weight, a phenomenon occurs that the strength decreases.

상기 황산알루미늄(Al2SO4)는 순도 90% 이상의 것을 사용하며, 고로수쇄 슬래그의 자극제로 사용되고, 에트링자이트 생성시켜 장기강도를 증진시킨다.The aluminum sulfate (Al 2 SO 4 ) is used with a purity of 90% or more, and is used as a stimulator of the blast furnace chain slag, and improve the long-term strength by producing ettringite.

상기 황산알루미늄은 0.1 중량% 미만으로 첨가시, 본 발명에 따른 효과를 기대하기 어렵고, 0.5중량%를 초과하여 첨가될 시, 에트링자이트의 과잉생성으로 인하여 균열이 발생된다.When the aluminum sulfate is added in less than 0.1% by weight, it is difficult to expect the effect according to the present invention, and when added in excess of 0.5% by weight, cracking occurs due to overproduction of ettringite.

상기 콘크리트용 골재는 KS F 콘크리트용 부순 골재를 사용한다.
The aggregate for concrete uses a crushed aggregate for KS F concrete.

상기와 같이 배합되는 흙배합물은 현장내에서 혼합되어 생성되거나, 레미콘 플랜트에서 생산되어 현장으로 이송될 수 있으며, 고로 수쇄 슬래그, 플라이애쉬, 마사토, 골재(자갈)를 배합하여 레미콘 트럭에 의해 현장으로 이송되는 것이 바람직하다.
Soil mixtures are mixed as described above can be mixed in the field, or produced in the ready-mixed concrete plant and transported to the site, by combining the blast furnace slag, fly ash, masato, aggregate (gravel) to the site by the ready-mixed truck It is preferred to be transferred.

또한, 상기 경화제는 가용성 특수 규산염과 물이 1 :1 의 중량비로 미리 배합되어 있으며, 현장에 설치된 연속 믹서펌프(혼합기)내에 흙배합물 및 경화재를 연속혼합하여 흙콘크리트 조성물을 생성한다.
In addition, the curing agent is pre-mixed with a soluble special silicate and water in a weight ratio of 1: 1, and continuously mixing the soil mixture and the hardening material in a continuous mixer pump (mixer) installed in the field to produce a soil concrete composition.

상기 경화제는 가용성 특수 규산염를 이용한 2차 배합물인 변성실리케이트(가용성 특수 규산염계) 배합물로, 이는 흙배합물에 더욱 높은 내화학적 특성과 내구성을 높이기 위하여 배합되며, 가용성 특수 규산염과 물이 1 :1 의 중량비로 배합되어 흙배합물에 첨가되면, 내염해성, 내산성 등의 향상되어 겨울철에 제설제로 쓰이는 염화칼슘에도 잘 견디는 고내수, 내구성의 특성을 구비하게 된다. The curing agent is a modified silicate (soluble special silicate-based) compound, which is a secondary compound using a soluble special silicate, which is blended in the soil mixture to improve chemical resistance and durability, and the weight ratio of soluble special silicate and water is 1: 1. When added to the soil mixture, it is improved in salt resistance, acid resistance and the like, and has high water resistance and durability characteristics that can withstand calcium chloride which is used as a snow removing agent in winter.

상기 가용성 특수 규산염은 포졸란 재료를 활성화시키는 최상의 재료로, 포졸란은 열처리나 알칼리에 의한 화학적 반응으로 활성화 되어야 하는데 가용성 특수 규산염은 포졸란의 실리카 성분을 활성화시키고, 실리카 또는 음이온 부분은 칼슘실리케이트 수화물을 형성하는 역할을 한다.The soluble special silicate is the best material for activating the pozzolanic material. Pozzolan should be activated by heat treatment or chemical reaction by alkali. Soluble special silicate activates the silica component of pozolan, and the silica or anion part forms calcium silicate hydrate. Play a role.

즉, 본 발명에 따른 가용성 특수 규산염은 규산소다와 물이 2 : 1 의 중량비로 희석되어 혼합액이 형성되고, 상기 혼합액과 7.0∼7.5 몰의 Na(OH)용액이 3 : 1 의 중량비로 혼합되어 155∼165℃에서 3∼6시간동안 반응기에서 반응시켜 형성한 1차 반응 규산염 100 중량부에, That is, in the soluble special silicate according to the present invention, a mixture of sodium silicate and water is diluted in a weight ratio of 2: 1 to form a mixed solution, and the mixed solution and 7.0 to 7.5 moles of Na (OH) solution are mixed in a weight ratio of 3: 1. To 100 parts by weight of the first reaction silicate formed by reacting in the reactor for 3 to 6 hours at 155 ~ 165 ℃,

내수성을 높이기 위하여 메틸셀룰로우스 3∼5중량부를 혼합한 후, 호모믹서기에서 1000∼1500 rpm 으로 2∼3분간 혼합하고, Tg = -10∼20℃ pH 8∼9, 고형분 30∼40wt%의 수용성 아크릴 에멀젼 20∼50 중량부를 분당 총량의 10%이내의 속도로 서서히 투입하면서 10∼20분간 혼합 반응시켜 형성한다.In order to improve water resistance, 3 to 5 parts by weight of methyl cellulose was mixed, and then mixed at a homomixer at 1000 to 1500 rpm for 2 to 3 minutes, and Tg = -10 to 20 ° C., pH 8 to 9, and a solid content of 30 to 40 wt%. 20 to 50 parts by weight of a water-soluble acrylic emulsion is formed by mixing and reacting for 10 to 20 minutes while gradually introducing at a rate within 10% of the total amount per minute.

이때, 상기 아크릴 에멀젼은 기준 pH이하의 것을 사용하거나 투입속도를 높이게 되면 규산염의 겔화 현상으로 반응성이나 내구성이 떨어지므로, 수용성 아크릴 에멀젼의 pH, 투입속도 및 투입량을 유지하여야 한다.
At this time, the acrylic emulsion is less than the reference pH or increase the feed rate, so the reactivity or durability is poor due to the gelation of silicate, it is necessary to maintain the pH, feed rate and dose of the water-soluble acrylic emulsion.

이와 같이 제조된 가용성 특수 규산염은 아크릴 에멀젼의 혼합으로 일반 규산들보다 내수성이 높고 증점제로 메틸셀룰로우스를 사용하여 규산의 분리 현상을 방지하며 일정한 품질을 유지할 수 있으며 흙배합물과의 반응을 향상시켜 흙콘크리트 조성물의 품질을 안정화시키는 기능을 구비하게 된다.
Soluble special silicate prepared in this way is more water-resistant than general silicates by mixing acrylic emulsion and using methyl cellulose as a thickener to prevent separation of silicic acid and maintain constant quality and improve reaction with soil mixture. It has a function to stabilize the quality of the soil concrete composition.

Figure 112013010881208-pat00001

상기 SiO2 는 7중량%를 초과할 경우, 강도특성이 좋아지나 경화특성이 늦어지고 조강성이 떨어지는 현상이 발생되며, Al2O3 는 33중량% 미만일 경우 조강성이 떨어지고 에트링자이트 생성이 작아져 내구성이 떨어지는 현상이 발생되며, Fe2O3 는 6중량% 미만일 경우 양질의 보크사이트를 사용하여야 하므로, 비용이 증대되게 된다. When the SiO 2 exceeds 7% by weight, the strength characteristics are good, but the curing property is slow and the roughness occurs, and when Al 2 O 3 is less than 33% by weight, the roughness is lowered and ettringite is produced. This decreases the durability is a phenomenon occurs, Fe 2 O 3 is less than 6% by weight because a good bauxite should be used, the cost is increased.

또한, 상기 CaO 는 상기 적정범위를 벗어날 경우 수축하거나 과팽창으로 경화체의 안정성이 떨어지고, MgO, TiO2 는 불순물로 위의 범위를 벗어나면 강도저하가 일어나며, SO3 는 8중량% 미만일 경우 에트링자이트 생성량 저하로 내구성 저하가 일어나게 된다. In addition, when the CaO is out of the appropriate range shrinkage or over-expansion, the stability of the cured body is deteriorated, MgO, TiO 2 is an impurity decreases in strength when out of the above range, SO 3 is less than 8% by weight The durability decreases due to the decrease in the amount of the generated zite.
