YANG Wen-ling,WANG Yu-jiang,WEN Jiu-ba School of Materials Science and Engineering,Henan University of Science and Technology,Luoyang 471003,Henan,China  
The effects of triethanolamine,glycerol and calcium lignosulfonate with different content as grinding aids on slag grinding process were studied at different time.The properties of slag cement with 50% slag powder and 50% Portland cement was tested.The results showed that the three types of grinding aids had good effect,and could reduce the slag fineness significantly and the content of the particles with diameter at 3-30μm increased.Considering the effect and economic cost of grinding,the best content of triethanolamine,glycerol,calcium lignosulfonate was 0.06%,0.04%,0.1% separately.
