Application of Sanming Steel Slag Powder in Cement and Concrete

Dong Mei Zhang, Ming Shi Lu, Feng Xing Liu

Abstract

Effects of steel slag powder on properties of cement and concrete are investigated. Results show that with the increase of steel slag power, water requirement of normal consistency is decreased, and the setting times are prolonged. The early mortar strength is lower, but late strength rate of increase is great. Steel slag powder is compatible with blast furnace slag. Moreover，concrete，which has harmonious development strength and excellent workability can be obtained by mineral additives two-element compounding.
