Description

건설자재용 경화체Hardening material for construction materials
본 발명은 건설자재용 경화체에 관한 것으로, 더욱 구체적으로는 화강토나 강모래 등과 같은 각종 토사(土砂)와 바닷모래 등과 같은 해사(海沙)의 단일물 또는 혼합물에 겔라이트가 함유된 경화제를 첨가하여 강도 및 내구성이 증진되고 친환경적인 석재대용으로 사용 가능한 물성을 갖는 건설자재용 경화체에 관한 것이다.The present invention relates to a hardening material for construction materials, and more specifically, a hardening agent containing gellite is added to a single substance or mixture of various types of soil sand such as granite soil and steel sand and sea sand. The present invention relates to a hardened material for construction materials having improved physical strength and durability and having properties usable as environmentally friendly stone substitutes.
일반적으로 토목공사 및 건설사업시에 제공되는 건설자재는 내구성과 강도를 유지하기 위한 친환경적인 양질의 자재를 필요로 하고 있으나, 이를 확보하기 어려운 상황으로 인해 공사기간이 지연됨으로써 건축경비를 증가시키는 요인으로 작용하게 되며, 건축자재 확보를 위하여 석산을 개발하거나 하천, 해상 등에서 골재채취를 함으로써 자연환경을 훼손하고 생태계를 교란시키고 있는 실정이다.In general, construction materials provided in civil engineering and construction projects require eco-friendly, high-quality materials to maintain durability and strength, but the construction period is delayed due to the difficulty of securing them, which increases construction costs. In order to secure construction materials, the development of quarries or the collection of aggregates from rivers and seas are undermining the natural environment and disturbing the ecosystem.
즉, 종래의 항만매립공법, 아스팔트 및 콘크리트 포장공법 등에서는 석재 등의 입상재료를 사용함으로 석재 채취를 위하여 산과 들을 훼손하고 있으며, 채석, 운반, 깨기 작업이 공사비를 증가시키는 요인이 되고 있다.That is, in the conventional port reclamation method, asphalt and concrete pavement method, using granular materials such as stone is damaging mountains and mountains for stone extraction, and quarrying, transportation, and breaking work are factors that increase the construction cost.
그리고 대부분의 하천제방 축조공법에서는 일반 토사를 사용함으로써 수류(水流) 압력에 의한 세굴 작용으로 내구성 및 안전성이 결여되어 제방이 붕괴 되고, 이로 인해 수해가 발생하고 질병이 확산 되었으며, 기존 연약지반 개량공법의 경우 공사비가 고가이고 사용재료의 손실율이 매우 커지는 등 문제점이 있다.In most river dike construction methods, general soils are used to wash down the dike due to lack of durability and safety due to scour action due to water pressure, resulting in flood damage and disease spread, and existing soft ground improvement methods. In the case of the construction cost is expensive and the loss rate of the material used is very large.
따라서, 이러한 문제점을 해결하기 위하여 우리나라 전역에 널리 분포되어 있는 토사 및 해사를 각종 토목공사 및 기타 건설사업에 석재 대용으로 재활용하기 위한 방안이 연구되어 왔다.Therefore, in order to solve this problem, a method for recycling soil and sea, which are widely distributed throughout Korea, as a substitute for stone in various civil works and other construction projects has been studied.
이러한 방안으로서, 종래에 시멘트 안정처리공법(Cement Stabilization), LAC(Lignin Rosin Asphalt Concrete) 공법 등이 개발되어 활용되고 있으나, 마무리 양생기간이 길어 조기 압축강도를 얻기 힘들며, 압축강도 또한 이하로 낮아 사용할 수 있는 분야가 도로건설의 보조기층재 등에 국한되어 있어서 활용성이 매우 낮았다.As such a method, cement stabilization method and Lignin Rosin Asphalt Concrete (LAC) method have been developed and utilized in the prior art, but it is difficult to obtain early compressive strength due to long finishing curing period and low compressive strength to be used. Its utilization is very low because it is limited to the auxiliary base materials of road construction.
또 다른 방법으로, 대한민국특허공개 제1996-29280호에 경화제 조성물을 사용하여 해사 및 토양 혼합물을 경화하는 방법이 개시되어 있다. 이때 사용된 경화제 조성물은 탄산나트륨 25%, 염화가리 25%, 탄산마그네슘 15%, 염화암모늄 10%, 규산화가리 8%, 실리케이트 7%, 황산철 5% 및 산화티탄 5%를 포함하도록 구성되어 있다. 이 경화제는 해사와 토양의 혼합물을 경화하기에 적합한 조성으로 기재되어 있으나, 탄산나트륨과 염화가리를 주성분으로 사용함으로써 제조비용이 고가이며, 이를 사용하여 제조되는 경화체의 강도 또한 크게 향상되지 못하여 널리 실용화되지 못하고 있는 실정이다.In another method, Korean Patent Publication No. 1996-29280 discloses a method of curing a seaweed and soil mixture using a curing agent composition. The curing agent composition used is composed of 25% sodium carbonate, 25% copper chloride, 15% magnesium carbonate, 10% ammonium chloride, 8% silicate silicate, 7% silicate, 5% iron sulfate and 5% titanium oxide. Although this curing agent is described in a composition suitable for curing a mixture of seaweed and soil, it is expensive to manufacture by using sodium carbonate and chlorine as the main components, and the strength of the cured product produced using the same is not greatly improved and thus is not widely used. I can't do it.

본 발명에 사용되는 토사로는 화강토, 이토, 강모래, 자연토사 등을 포함하여 통상 토사류로 분류되는 것이라면 제한됨이 없이 사용될 수 있으며, 화강토 단일 또는 화강토와 그 외 토사류와의 혼합물이 바람직하다.The earth and sand used in the present invention can be used without limitation as long as it is classified as a general soil type, including granite soil, Ito, river sand, natural soil, etc., preferably a single granite soil or a mixture of granite soil and other soil soils. Do.
일반적으로 해사는 바닷모래와 사막모래를 지칭하는 것이며, 본 발명에 사용되는 토사와 해사는 각각의 단일(單一)로 사용될 수 있으며, 토사혼합물이나 해사혼합물로도 사용될 수 있고, 토사와 해사를 혼합한 토사 및 해사혼합물로도 사용 가능하다.Generally, the sea sand refers to sea sand and desert sand, and the sand and sea sand used in the present invention may be used as a single piece, and may also be used as a soil sand mixture or a sea sand mixture. It can also be used as a soil and marine mixture.
상기 결합제는 시멘트 및 겔라이트 미분말을 포함하되 그 함량이 결합제 5 중량부 미만이면 강도 및 균열발생 억제 효과가 떨어지고, 15 중량부 이상이면 빠른 경화특성으로 좋은 물성으로 갖게 되지만 제조원가의 상승을 초래하고 경제성이 떨어지게 되므로 토사 또는 해사 또는 토사와 해사를 포함한 2종 이상의 혼합물 100중량부에 대하여 결합제는 5 내지 15중량부로 함유되는 것이 바람직하다. The binder includes fine cement and gellite powder, but if the content is less than 5 parts by weight of the binder, the strength and cracking inhibiting effect is inferior, and if the content is more than 15 parts by weight, the curing property has good physical properties due to fast curing properties, but it causes an increase in manufacturing cost and economics. Since it will fall, it is preferable that the binder is contained in 5 to 15 parts by weight based on 100 parts by weight of two or more mixtures including earth or sea sand or earth and sea sand.
그리고 결합제에 포함되는 겔라이트 미분말은 시멘트 100중량부에 대하여 겔라이트 분말 20~30 중량부로 조성함이 바람직한 것으로, 겔라이트 미분말이 20 중량부 미만이면 겔라이트의 원적외선 및 항균성 등의 기능을 저하되어 시멘트 중화 효과가 떨어지고 30 중량부 이상이면 결합강도가 떨어지게 된다.In addition, the fine gellite powder contained in the binder is preferably composed of 20 to 30 parts by weight of gelite powder with respect to 100 parts by weight of cement. When the fine gelite powder is less than 20 parts by weight, the functions of gelite, such as far infrared rays and antimicrobial properties, are lowered. If the cement neutralization effect is poor and more than 30 parts by weight, the bond strength is lowered.
상기 겔라이트는 화산회로 이루어진 것으로서 납석의 일종으로 시멘트 반응성을 가지고 있어 적절한 함수율의 무기성 슬러지의 고형화에 적합하고 시멘트와 친화성으로 잠재 수경성 특성, 장기강도발현 및 내구성을 증진 시킬 수 있도록 할 뿐만 아니라 원적외선 방출 및 항균성이 우수하므로 시멘트 독성을 중화시키는 작용으로 친환경적인 물성을 갖도록 한다.The gelite is a volcanic circuit, which is a kind of feldspar, which has cement reactivity, which is suitable for solidifying inorganic sludge of appropriate moisture content, and can improve latent hydraulic properties, long-term strength expression and durability with affinity with cement. Since it has excellent far-infrared emission and antibacterial property, it has an effect of neutralizing cement toxicity to have eco-friendly properties.
상기 증점제는 점도를 높이고 흐름성을 방지하기 위하여 사용되는 것으로서 내수성이 좋은 우레탄계 증점제가 됨이 바람직하다.The thickener is used to increase the viscosity and prevent flowability, it is preferable to be a urethane-based thickener having good water resistance.
상기 소포제는 도막 내의 기포 발생 등 도막 결합을 방지하기 위한 것으로, 기포가 도막 내에 잔류하는 경우에 부착불량 또는 도막의 물리적 물성의 저하를 가져올 수 있다. 이러한 소포제는 소포력을 극대화할 수 있는 실리콘계 소포제를 사용함이 바람직하다.The antifoaming agent is for preventing the coating film bonding, such as the generation of bubbles in the coating film, when the bubbles remain in the coating film may result in poor adhesion or deterioration of the physical properties of the coating film. Such antifoaming agent is preferably to use a silicone-based antifoaming agent that can maximize the defoaming power.
상기 경화제는 염화나트륨(NaCl), 탄산나트륨(Na2Co3) 탄산칼륨(K2Co3), 염화마그네슘(MgCl2), 염화칼슘(CaCl2)으로 조성되어 토사 및 해사에 강도를 부여하며 건조수축으로 인한 균열을 방지하는 역할을 한다.The curing agent is composed of sodium chloride (NaCl), sodium carbonate (Na 2 Co 3 ) potassium carbonate (K 2 Co 3 ), magnesium chloride (MgCl 2 ), calcium chloride (CaCl 2 ) to give strength to soil and sea sand, and to dry shrinkage Prevents cracks caused by
경화제 조성물에서 염화나트륨 및 탄산나트륨, 탄산칼륨은 시멘트의 Ca이온 침투능력을 증진시킬 수 있도록 하며, 그 함량이 각각 20 중량부 미만인 경우에는 시멘트의 응결 작용(분산)작용이 불충분하여 강도상승효과가 어려운 문제점이 있으며, 각각 30 중량부 이상이면 용해능력이 떨어지는 경우가 발생할 수 있으므로 경화제 총 중량에 대하여 염화나트륨 및 탄산나트륨, 탄산칼륨은 각각 20~30 중량부로 함유되는 것이 바람직하다.Sodium chloride, sodium carbonate, and potassium carbonate in the curing agent composition can enhance the Ca ion penetrating ability of the cement, and if the content is less than 20 parts by weight, it is difficult to increase the strength due to insufficient cement coagulation (dispersion) action. There is a case in which the dissolving ability may be lowered if each is more than 30 parts by weight, so sodium chloride, sodium carbonate and potassium carbonate are preferably contained in an amount of 20 to 30 parts by weight based on the total weight of the curing agent.
염화 마그네슘은 조성물의 축소 및 팽창을 방지하여 주는 작용을 하며 이온을 저해하고 있는 유기물의 이온과 반응하여 유기물의 흡착수를 탈취함과 동시에 흙 입자주변 물 분자도 이온군 외로 방출하는 효과를 발휘하게 되는 것으로, 그 함량이 15 중량부 미만인 경우에는 조성물의 축소 및 팽창이 과도하게 이루어져서 결합력이 떨어지는 문제점이 있고, 20 중량부 이상인 경우에는 탄력성 저하로 안정성이 떨어지는 문제점이 있으므로 경화제 총 중량에 대하여 15~20 중량부로 함유되는 것이 바람직하다.Magnesium chloride acts to prevent shrinkage and expansion of the composition, and reacts with the ions of organic substances that inhibit ions to deodorize the adsorbed water of the organic matter and to release the water molecules around the soil particles out of the ion group. If the content is less than 15 parts by weight, there is a problem in that the shrinkage and expansion of the composition is excessively made and the bonding strength is lowered, and in the case of more than 20 parts by weight, there is a problem in that the stability is lowered due to a decrease in elasticity, 15 to 20 with respect to the total weight of the curing agent It is preferable to be contained by weight part.
염화칼슘(CaCl2)은 시멘트와 혼합하여 흡수성을 촉진하고 동결을 방지하는 촉매제 역할을 하는 것으로서, 그 함량이 경화제 총 중량에 대하여 15 중량부 미만의 양이 함유될 경우 수분과의 원활한 수용이 되지 않아 동결 방지효과가 약하게 되는 문제점이 있을 수 있으며, 그 함량이 20 중량부 이상인 경우에는 무수물이 다량 발생하여 경화제가 액상을 이루기 어려운 문제점이 있을 수 있으므로, 경화제 총 중량에 대하여 15~20 중량부로 함유되는 것이 바람직하다.Calcium chloride (CaCl 2 ) acts as a catalyst to promote absorption and prevent freezing by mixing with cement. When the content is less than 15 parts by weight based on the total weight of the curing agent, calcium chloride (CaCl 2 ) is not easily accommodated with moisture. There may be a problem that the freeze-preventing effect is weak, if the content is more than 20 parts by weight of the anhydride may occur a large amount because the hardener is difficult to form a liquid, it is contained in 15 to 20 parts by weight relative to the total weight of the curing agent It is preferable.
물은 함수비(含水比)의 적응력을 수용하여 상기 성분들을 제외한 잔량을 차지하도록 함유된다. 물이 지나치게 소량 함유될 경우 유화 분산이 제대로 일어나지 않게 되는 문제점이 있을 수 있으며, 과량 함유될 경우 혼합물 입자 간 접착성, 방수력 및 강도저하를 초래하는 문제점이 있을 수 있으므로, 물의 함유량 또한 적합한 범위로 조절하여야 하며, 이러한 물의 함량은 경화제 총 중량에 대하여 약 72 내지 80중량부로 함유되는 것이 바람직하다Water is contained to accommodate the remaining capacity except the above components to accommodate the adaptability of water content. If too little water is contained, there may be a problem that the emulsion dispersion does not occur properly. If too much water is present, there may be a problem that causes adhesion between the particles of the mixture, water resistance and strength decrease, so that the content of water is also adjusted to an appropriate range. The amount of water is preferably contained in about 72 to 80 parts by weight based on the total weight of the curing agent.
