Reuse of Glass Industrial Wastes and Waste Granite Powder in Cement Products

Abstract

This paper presents the results of a study conducted to evaluate the possibility of utilizing the Grounded Glass
Waste (GGW), Granite Powder (GP) and Grounded Granite Powder (GGP) as a partial replacement of cement. The
influence of GGW, GP and GGP on the compressive strength of mortars was investigated. In addition, X-ray diffraction
analysis was performed, to evaluate the pozzolanic activity. The results show that the incorporation of the GGW and GP
yields mortars with improved strengths at the later ages (28 and 91 days), in comparison with that of a control mortar
(ordinary Portland cement only); while the GGW and GP caused lower early ages (3 and 7 days) strength than that of
control. The density of the mortars can be reduced by incorporating GGW, GP and GGP. These results indicate that the
GGW and GP have higher reactivity; and therefore, can be used as a pozzolanic admixture in cement composites.
