Résumé

The purpose of this experimental investigation is to examine the effect of ceramic and glass waste powders as partial cement substitution on the rheological properties and compressive strength of sustainable self-compacting mortar. Nine mixtures have been tested, one as reference mixture and includes only Ordinary Portland cement (OPC), and eight including different proportions of ceramic and glass powders (5, 15, 25 and 50%). The rheology test was carried out to determine yielded stress and plastic viscosity of fresh mortar. Compressive strength was also measured at 28 and 90 days. Experimental results demonstrate that replacing part of cement caused a reduction of the rheological properties, exception for CP in which substitution levels inferior to 25% slightly increased the yield stress. Using GP with 25% resulted in 28 days-compressive strength superior by about 3% to that of the plain cement.
