CHEMICAL LIQUID FOR GROUTING

摘要

PURPOSE:To obtain the titled chemical liquid giving high consolidation strength because of no gas generation in the consolidated mass with the strength increasing with time, by blending water-glass and dicalcium silicate made by calcination of calcium carbonate and silica sand powder. CONSTITUTION:The objective chemical liquid can be obtained by mixing (A) an aqueous suspension of dicalcium silicate made by calcination at >=1,400 deg.C of a blend prepared from calcium carbonate and silica sand powder so as to result in the approximate composition: 2CaO . SiO2 and (B) water-glass.
