SOLIDIFIED AGENT TO STRENGTHEN STRATUM

摘要

PURPOSE: A solidifying agent is provided to obtain activate the solidifying strength by activating hydraulic property of a blast furnace slag and to remove pore water in an expansion agent by using a exothermic reaction and volume expansion function. CONSTITUTION: A solidifying agent comprises 20-50 parts by weight of petroleum cokes calcium sulfate and 40-100 parts by weight of an expansion agent based on 100.0 parts by weight of a blast furnace slag micropowder. The expansion material is one or a mixture of two more selected from a biomass incineration bottom ash, paper sludge incineration bottom ash, and RDF(Refuse Plastic Fuel) incineration bottom ash. The expansion agent contains 20-70% of calcium oxide(CaO).
