Abstract

A mathematical model simulating the packing density of blended cement with limestone having different particle sizes added in various quantities was derived from models created by Stovall and de Larrard and was developed based on a linear packing density model of grain mixtures. The predicted packing density was validated by experimental values. Following our small and simple modifications, the Stovall and de Larrard models could accurately simulate the packing densities of blended cements with different particle sizes in various combinations, mainly those related to the interaction functions accounting for loosening l(r) and wall w(r) effects and the compaction index, K.
