Slag powder is high-performing admixture for concrete in that it increases the concretes ability to resist compression, tension, shear, and bending stresses. A major trend that characterizes the building material industry is to replace equal amount of cement with slag powder in making concrete or cement products.

Cement - Cement - History of cement The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe.
