Physical and Chemical Properties of Steel Slag and Utilization Technology of Steel Slag at Home and Abroad

Abstract

Steel slag is a large discharge of industrial waste slag. Chinese effective utilization rate of steel slag is only 20%, causing great harm to the environment and economy. Based on the introduction of the element, composition and characteristics of steel slag, this paper expounds the application of steel slag in sintering and blast furnace production, steel slag cement, road engineering, agricultural fertilizer and environmental protection at home and abroad.
