摘要

PURPOSE: An environmentally friendly soil hardening agent is provided to provide environmentally friendly soil by not using cement, be able to be hardened in a short time by not needing a large amount of water, and have the same or a better hardening function compared to using cement.;CONSTITUTION: An environmentally friendly soil hardening agent comprises 20-50% of potassium oxide(K2O); 10-30 wt% of aluminum oxide(Al2O3); 75-90 wt% of a first composition(A) which consists of 1-10 wt% of ferric oxide (Fe2O3); 5-20 wt% of a second composition(B) which consists of a mixture of chitosan powder and used oyster shell powder and has a specific gravity of 2.82; and 0.5-5 wt% of red clay(C) which has a particle size of 0.1-50 um. The second composition comprises waste oyster shell powder of which 50-60 wt% has a particle size of 200-400 mesh; and chitosan powder of which 40-50 wt% has a molecular weight of 100,000, a particle size of 200-400 mesh, and a deacetylation degree of 95%.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Stir; (BB) Harden
