Composition for hardening soil wastes sea sand or desert sand and hardening composition comprising the same

摘要

An objective of the present invention is to provide a hardening composition which is capable of hardening earth and sand, wastes, sea sand and desert sand such that earth and sand, wastes, sea sand and desert sand have fast hardening speed, excellent strength and excellent elasticity. The present invention provides the hardening composition and a hardened body composition comprising the same, the hardening composition comprising 1 to 5 parts by weight of a compound represented by chemical formula 1, 1 to 3 parts by weight of sodium chloride, 0.5 to 1 part by weight of aluminum tris(O-ethyl phosphonate), 1 to 3 parts by weight of potassium chloride, 1 to 2.5 parts by weight of calcium chloride, 0.2 to 2 parts by weight of magnesium oxide, 0.2 to 1.5 parts by weight of sodium sulfate, 0.2 to 2 parts by weight of Na_2SiO_3, 0.2 to 1 part by weight of lignin sulfonic acid salt, and 100 parts by weight of cement. In chemical formula 1, R_1 and R_2 are each independently hydrogen or a methyl group, and m is 0.3 to 0.7 and n is 0.3 to 0.7 at a molar ratio of m to n.
