Granulated Blast Furnace Slag - an overview ...

Granulated phosphorus slag is a latent cementitious material but less reactive than granulated blast-furnace slag at early age due to the lower Al 2 O 3 content and the presence of P 2 O 5 and F. A hydraulic index of phosphorus slag is defined as follows ( Shi et al., 2006; RCT 5024-83, 1983 ):
