| 摘要 |
The present invention relates to a hardened body for construction material which can be used as a stone substitute, the hardened body having properties of improved strength and durability and environment-friendliness from having gelite-containing hardening agent added in a single-ingredient solution or a mixture composed of a variety of soils, such as weathered granite soil, river sand and others, and marine sand such as ocean sand and others. Specifically, the composition, with respect to a 100 weight parts of a mixture of two or more types comprising soil, marine sand or both soil and marine sand, according to the present invention is 2-8 wt parts diluted hardening agent solution, 5-15 wt parts bonding agent which is a mixture of cement and gelite powder, 2-8 wt parts adhesive agent, and 0.5-1 wt parts anti-foaming agent, wherein the diluted hardening agent solution is composed of 200-400 wt parts water to 100 wt parts hardening agent, and the hardening agent is composed of 20-30 wt parts sodium chloride (NaCl), 20-30 wt parts sodium carbonate (Na2Co3), 20-30 wt parts potassium carbonate (K2Co3), 15-20 wt parts magnesium chloride (MgCl2), and 15-20 wt parts calcium chloride (CaCl2). |
