ORGANIC-INORGANIC COMPLEX NONE-CEMENT SOIL CONCRETE COMPOSITION AND SECONDARY PRODUCTS OF SOIL CONCRETE

The present invention relates to an organic-inorganic complex uncemented soil concrete composition using a binding material comprising inorganic materials of slag, lime, gypsum, and silica fume, and casein which is an organic material; and to secondary products manufactured from the soil concrete composition, such as blocks, bricks, panels, etc. Provided is an organic-inorganic complex uncemented soil concrete composition which is formed by adding and mixing 10 to 200 parts by weight of an inorganic binding material based on 100 parts by weight of the soil, and 0.05 to 10 parts by weight of casein based on 100 parts by weight of the inorganic binding material. The inorganic binding material comprises: 60 to 90 wt% of slag fine powder, 3 to 25 wt% of lime, 4 to 10 wt% of gypsum, 1 to 10 wt% of limestone fine powder, and 0.1 to 5 wt% of silica fume. The present invention is to use the soil as a construction material. Provided are the soil concrete composition which sufficiently shows improved physical properties such as compression strength, water resistance, etc., without using cement; and secondary products of the soil concrete. 본 발명은 무기물인 슬래그, 석회, 석고 및 실리카흄으로 구성된 결합재와 유기물인 카세인을 이용한 유·무기 복합 무시멘트 흙 콘크리트 조성물 및 이러한 흙 콘크리트 조성물로 제조된 블록, 벽돌, 패널 등의 2차제품에 관한 것이다. 본 발명은 「슬래그미분말 60~90wt%, 석회 3~25wt%, 석고 4~10wt%, 석회석미분말 1~10wt%, 실리카흄 0.1~5wt%를 포함하여 조성된 무기결합재를 흙 100중량부 대비 10~200중량부 혼합하고, 카세인을 상기 무기결합재 100중량부 대비 0.05~10중량부 더 첨가하여 혼합한 것을 특징으로 하는 유·무기 복합 무시멘트 흙 콘크리트 조성물」을 제공한다.
