ECO-FRIENDLY LOW CEMENT-BASED SOLIDIFYING COMPOSITION FOR WEAK GROUND AND METHOD OF SOLIDIFYING SOIL USING THE SAME

摘要

PURPOSE: An eco-friendly low cement-based solidifying composition for weak ground is provided to secure an application property due to improved mobility and compressive strength, to minimize the amount of cement and the elution of waste treatment cost by reducing the discharge sludge. CONSTITUTION: An eco-friendly low cement-based solidifying composition for weak ground comprises (a) 55-70 weight% of blast furnace slag powder, (b) 20-35 weight% of cement powder, (c) 5-15 weight% of plaster powder and (d) 1-10 weight% of solid acid catalyst. The blast furnace slag is an amorphous state and has basicity of 1.6~2.0. The blast furnace slag comprises 40-50 weight% of CaO, 1-10 weight% of MgO, 10-25 weight% of Al2O3, and 30-40 weight% of SiO2.
