Blast Furnace Cement - an overview | ScienceDirect Topics

The beneficial effect of blast furnace slag on the alkali silicate reaction was reported in [44], and the effect has two parts: First, blast furnace slag cement has a denser pore structure than Portland cement, and this hampers different transport processes needed for alkali silica reaction. Second, blast furnace slag cement has a lower pH than Portland cement, which reduces the alkali silica reaction (a higher …
