Effects of limestone filler fineness on the rheological behavior of cement – Limestone filler grouts

An acceptable viscosity and an easy penetrability of cement - limestone filler grout in the granular matrix of self compacting concrete are an important factors that affecting both its rheological and its hardened properties. This experimental and theoretical work consists to study the effect of lim...
