Mineral Admixture - an overview | ScienceDirect Topics

A great variety of mineral admixtures can be used as replacement for cement in concrete to improve certain properties of concrete, as explained in Chapter 1 (Aïtcin, 2016a). As for any powder, their particle size distribution, specific gravity, morphology and interparticle forces are the major factors affecting their rheological behaviour.
