Limestone as an accelerator and filler in limestone ...

Abstract The effect of substitution of alumina cement by limestone up to 25% as well as its fineness on the physico-mechanical properties of the hardened cement pastes is studied. The results revealed that the replacement of alumina cement by limestone slightly decreases the water of consistency and the setting times (initial and final). The combined water content increases with the curing ...
