Description
본 발명은 산화칼슘을 이용한 콘크리트양생방법에 관한 것으로서 더 자세하게는 시멘트배합물에 분말산화 칼슘을 물과 혼합하여 가볍고 강도가 강한 콘크리트를 제공하는 산화칼슘을 이용한 콘크리트양생방법에 관한 것이다.The present invention relates to a concrete curing method using calcium oxide, and more particularly to a concrete curing method using calcium oxide to provide a light and strong concrete by mixing powdered calcium oxide with water in a cement mixture.
일반적인 콘크리트는 철강재와 같이 토목.건축용 자재중에서도 중요한 건설재료로서, 시멘트.잔 골재.굵은골재.물 및 혼합재료를 적당하게 굳을 수 있도록 혼합하여 사용한다.General concrete is an important construction material among civil engineering and building materials, such as steel, and it is used to mix cement, fine aggregate, coarse aggregate, water, and mixed materials to be appropriately hardened.
콘크리트배합은 콘크리트를 만드는 재료 즉 시멘트.물.골재.혼합제 등을 혼합하는 것으로 예전에는 시멘트.잔 골재.굵은 골재의 비율을 용적비로 1:2:4 또는 1:3:6등으로 나타냈으나,최근에는 주로 각 재료의 단위량을 표시하며 중량비를 사용하고 있으나, 중량과 자중(自重)이 크기 때문에 대형건물인 경우 길이나 크기에 제한을 받게 된다.Concrete mixing is a mixture of materials that make concrete, such as cement, water, aggregate, and mixture. In the past, the ratio of cement, fine aggregate, and coarse aggregate was 1: 2: 4 or 1: 3: 6 in volume ratio. In recent years, the unit weight of each material is mainly expressed and the weight ratio is used. However, since the weight and the weight are large, large buildings are limited in length or size.
이러한 콘크리트의 중량을 제거하기 위해 보완한 것으로서 대한민국 특허공고번호 제73-53호의 경량콘크리트 벽돌제조방법에서는 기포안정제로 PVA 및 CMC를 첨가하고, 염화칼슘과 규산 나로리움에 침적시킨 톱밥을 혼합시킨 후 방향족 용제로 처리한 후 규산 나토리움 용액에 침적시키는 기술이 개시된바 있다. 그러나, 상기 종래의 기술은 기포 안정제와 방향족용재 등의 재료를 별도로 첨가하여 사용하고 있기 때문에 완성제품의 단가가 상승되어 결국 경쟁력이 저하되는 문제점을 가지고 있다.As a supplement to remove the weight of the concrete, in the method of manufacturing lightweight concrete brick of Korean Patent Publication No. 73-53, PVA and CMC are added as bubble stabilizers, a mixture of calcium chloride and sawdust deposited in narium with silicate is aromatic Techniques have been disclosed for treating with a solvent and then immersing in a solution of sodium silicate. However, the conventional technology has a problem in that the cost of the finished product is increased because of the addition of a material such as a bubble stabilizer and an aromatic solvent separately, resulting in a decrease in competitiveness.
본 발명은 이와 같은 종래의 제반 문제점을 해결하기 위기 위해 안출한 것으로서 그 목적은 저가의 석회석이나 조개껍질 등을 테워 만든 산화칼슘을 시멘크와 혼합하여 콘크리트를 제조함으로써 저가의 경량콘트리트를 제조할 수 있고 내부의 칼슘기공을 통해 보온 단열효과를 향상시키고자 하는 데 있다.The present invention has been made in order to solve such a conventional problem, the purpose is to produce a low-cost lightweight concrete by producing concrete by mixing calcium oxide made of teem limestone, shells, etc. with seamen It is to improve the thermal insulation effect through the internal calcium pores.
이하, 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.
본 발명은 산화 칼슘이 배합된 시멘트를 이용하여 경량의 콘크리트를 양생하는 방법에 관한 것으로서 석회석 또는 조개껍질을 적정온도로 태워 적정량의 산화칼슘분말가루를 만들고, 상기 산화칼슘분말가루를 골재에 물과 혼합한 시멘트배합물과 섞고, 상기 시멘트배합물을 시공하고자 하는 장소 또는 성형틀안에 채워넣고 건조시켜 완성한다.The present invention relates to a method for curing lightweight concrete using cement containing calcium oxide, and to burn limestone or shells at an appropriate temperature to make an appropriate amount of calcium oxide powder, and to add the calcium oxide powder to aggregate The mixture is mixed with the mixed cement mixture, and the cement mixture is filled in a place or a forming mold to be constructed and dried.
이와 같은 본 발명의 작용효과를 설면하면 다음과 같다.The functional effects of the present invention are as follows.
본 발명은 산화 칼슘이 배합된 시멘트를 이용하여 경량의 콘크리트를 양생하는 방법에 관한 것으로서, 콘크리트를 완성하기 위한 방법으로 먼저, 산화칼슘(CaCO3)을 함유하고 있는 석회석이나 조개껍질을 약 750℃~950℃정도의 고열에 가열하여 탄산가스(C02)를 배출하고 남은 산화칼슘(CaO)분말가루를 모은다.The present invention relates to a method for curing lightweight concrete by using a cement compounded with calcium oxide. First, a method for completing concrete is first performed by using a limestone or shell containing calcium oxide (CaCO 3 ) at about 750 ° C. The carbon dioxide (C0 2 ) is discharged by heating at a high temperature of ˜950 ° C and the remaining calcium oxide (CaO) powder is collected.
한편, 물과 골재 등을 섞인 시멘트배합물은 산화칼슘분말가루의 약 10%~30%량과 다시 섞어 혼합한다.On the other hand, the cement mixture mixed with water and aggregate is mixed again with about 10% to 30% of the calcium oxide powder powder.
이때 산화칼슘분말가루가 섞인 시멘트배합물은 혼합한 물과 산화칼슘분말가루가 섞이면서 무수한 기포를 형성시켜 시멘트배합물 전체 부피가 커지게 된다.At this time, the cement mixture in which the calcium oxide powder is mixed is mixed with water and the calcium oxide powder to form a myriad of bubbles to increase the total volume of the cement mixture.
이와 같이 무수히 많은 기포가 형성된 시멘트배합물을 시공장소나 성형틀안에 넣어 채움으로서 시멘트배합물은 무수한 기포를 전체적으로 형성하면서 그대로 건조되어 원하는 틀이 형성되어 결국 완재품의 콘크리트가 완성되는 것이다.Thus, by filling the cement compound in which a myriad of bubbles are formed in a city factory or a molding mold, the cement compound is dried as it is while forming a myriad of bubbles as a whole to form a desired mold, and finally the finished concrete is completed.
이와 같이 작용하는 본 발명은 무수히 많은 기포를 함유하는 콘크리트는 중량이 가벼워 건축자재용으로 실용성이 높으며, 그 크기를 크게 제작가능할 수 있어 시멘트 벽돌을 2중으로 설치하지 않고도 충분히보온단열의 효과와 강도를 높일 수 있으며, 별도의 팽창재 없이도 주위에 구하기 쉬운 석회석이나 조개껍질을 이용한 산화칼슘만으로도 충분히 경량, 보온단열성을 갖춘 콘크리트를 양생할 수 있어 경제성이 뛰어난 제품을 제공하는 효과를 갖는다.The present invention that acts in this way is a concrete that contains a myriad of bubbles are light weight, high practicality for building materials, and can be manufactured large in size, so that the effect and strength of sufficient thermal insulation without double installation of cement brick It can be increased, and it is possible to cure concrete with light insulation and insulation sufficient enough with calcium oxide using limestone or clam shell, which is easy to get around without the need for an additional expansion material.
