Detail
The present invention provides a method for manufacturing a high-strength blast furnace slag cement-based solidification agent that can exhibit the same strength even when used only about 60% instead of blast furnace slag cement used for improving soft ground.
To this end, blast furnace slag cement, anhydrite, and quicklime are mixed to increase the powdery consistency, and then a polycarboxylic acid-based admixture is added to manufacture the agent. This can be used in a soil cement method. This method can reduce the amount of existing blast furnace slag cement used by 40%.
