SOLIDIFYING MATERIAL FOR REINFORCING GROUND CAPABLE OF IMPARTING HIGH SOLIDIFICATION STRENGTH BY ACTIVATING LATENT HYDRAULICITY BY USING A DESULFURIZED GYPSUM IN PETROLEUM COKE AS A STIMULANT

摘要

PURPOSE: A solidifying material for reinforcing ground is provided to remove pore water in soil by using exothermic reaction and a volume expansion reaction of calcium oxide in a blowing agent, thereby stabilizing ground in quick time.;CONSTITUTION: A solidifying material for reinforcing ground comprises 40-50 parts by weight of a desulfurized gypsum in petroleum coke and 40-100 parts by weight of a blowing agent on the basis of a blast furnace slag. The blowing agent is a flyash of which content of calcium oxide(CaO) is 20-70%. The blowing agent additionally comprises a mixture of one or more selected from a group consisting of electric slag dust, quicklime, and dolomite.;COPYRIGHT KIPO 2012
