PROBLEM TO BE SOLVED: To provide a soil hardening material which develops strengths at an early stage and enables transition to a neutral state at an early stage by inhibiting increase of pH. SOLUTION: This soil hardening material contains quicklime, blast-furnace slag and a waste plaster board and contains zeolite as a pH adjuster. The soil hardening material develops strengths at an early stage through mixture of the quicklime, the blast-furnace slag and lime of the waste plaster board with water in the soil. The zeolite enters the soil to produce a buffering action, which inhibits increase of pH of the soil and helps its transition to a neutral state at an early stage. COPYRIGHT: (C)2006,JPO&NCIPI |
