Rheology of concrete with crushed aggregate. Influence of volume and composition of matrix, and of sand-stone ratio

Abstract

The work is a part of the joint industry project "MIKS – Microproportioning of concrete with crushed sand". The overall aim of the work reported here was to provide experimental data as input to the work on the Particle-Matrix-Model (PMM) to predict workability in terms slump-flow, of self-compacting concrete with crushed aggregate and fines. The results confirm that concrete with crushed fines and aggregate follow the principle of the model originally developed for natural aggregates, and thus that PMM can be adapted to concrete with crushed aggregate.
