AN AGENT FOR HIGH STRENGTH OF TERNARY BLENDED CEMENT AND TERNARY BLENDED CEMENT INCLUDING THE SAME

摘要

The present invention relates to a strength enhancer composition for ternary blended cement and a ternary blended cement including the same. The strength enhancer composition includes: 30-80 parts by weight of calcium aluminate slag; 5-15 parts by weight of petrolem coke flue gas desulfurization plaster; 5-15 parts by weight of fluidized bed boiler ash; and 5-30 parts by weight of alkali stimulant. As such, the present invention is capable of promoting an initial hydration reaction of ternary blended cement and improving an initial speed thereof, and reducing costs for treating industrial byproducts and preventing environmental pollution. According to the present invention, since a calcium oxide (CaO) contained in general Portland cement and furnace slag powder is stimulated and an ettringite reaction of fly ash is activated, the present invention is capable of solving a low initial strength problem of ternary blended cement and also making midterm and long term strengths stable. Moreover, as industrial byproducts, which have to be generated from industrial processes, are able to be recycled to be used as a strength enhancer composition for ternary blended cement, the present invention is capable of reducing costs for treating the byproducts and preventing environmental pollution.
