Effects of Ground Granulated Blast Furnace Slag in Portland Cement ...

of the overall cement matrix. Using slag cement as a replacement material for OPC changes the rate of strength gain because the hydration properties of slag cement are different from OPC. Slag cement is a latent hydraulic material, meaning that with use of this material, the rate of strength gain will be lower when compared to OPC concrete.
