Present State and Prospect on Use of High Fineness Granulated Blastfurnace Slag in Concrete

Abstract

Blastfurnace slag cement has been used widely as a structural material due to the latent hydraulicity of ground granulated blastfurnace slag (GGBS) for a long time. Recently, high fineness GGBS has been able to make mass-production with the aid of the development of grinding technology. This paper describes mainly the circumstances of the development, related standards of foreign countries, properties and future subjects of investigation of low heat slag cement with a large quantity of high fineness GGBS, and also mentions the present state and prospect on the other uses of high fineness GGBS.
