ENVIRONMENT-FRIENDLY GEOPOLYMER COMPOSITION FOR STABILIZATION OF SOFT GROUND AND STRENGTH ENHANCEMENT AND THE METHOD USING THEREOF

摘要

The present invention relates to an environmentally friendly geopolymer composition for the stabilization and strength enhancement of soft ground and a construction method using the same and, more specifically to an environmentally friendly geopolymer formed by mixing 30-70 wt% of blast furnace slag powder, 10-40 wt% of cement, 1-30 wt% of antishrinking agents, 1-10 wt% of quick setting blending materials and 0.1-5 wt% of alkali activators. The present invention enables an environmentally friendly construction preventing environmental pollution by manufacturing the geopolymer composition manufactured by minimizing cement consumption and using pozzolan materials such as blast furnace slag powders, facilitates pumpability by high fluidity, enables self-build using chute and is able to prevent volume contraction from being caused by absorbing surplus water after construction and being expanded.
