Effect of content and fineness of slag as high volume cement ...

Replacement of cement by slag in ultra-high performance concrete (UHPC) makes it a green material for building and construction application. However, slag hydrates slower which delay strength gain in UHPC which can be addressed by using slag of high fineness. In this study, cement is replaced by slag at 20% and 60% by weight.

replacement for cement provides a significant increase in strength of concrete (Xiaofeng et al., 1992). The addition of silica fume to cement paste has been shown to give rise to high early strengths (Mitchell et al., 1998). Silica fume is used in concrete for increased strength development, reduced permeability and economy (Francis, 1994). Mineral
