Study on the Performance of Green Cement with Large Amount of Steel Slag Addition

Abstract

In this paper, the experimental study of steel slag cement is carried out. The waste steel slag is used as one of the raw materials for cement production. According to the chemical composition and physical properties, the optimum admixture ratio of steel slag for cement production is 20%. Active SiO2 as additive can improve the strength, shrinkage, stability and concrete performance of steel slag cement. The utilization of waste steel slag is beneficial to environmental protection and achieving the goal of turning waste into treasure.
