EXPERIMENTAL STUDY OF PHYSICAL AND MECHANICAL PROPERTIES OF CONCRETE BY WASTE GLASS POWDER AS PARTIAL REPLACEMENT OF CEMENT

The environmental problem posed by non-biodegradable waste, such as non-reusable glass bottles, is becoming a major concern in view of the huge quantities in landfills in underdeveloped countries. Prospecting the valorization of waste glass in rural constructions constitutes a potential to reduce the use of natural materials in concrete industry. In this paper, the issues of environmental and ecological construction materials are addressed by the use of waste glass powder (Ø≤80μm) as replacement of cement in concrete. The aims of this project work is to usewaste glass powder in range of 10wt% to 20wt% as replacement of cement into concrete and concrete cylinder tested for its density, workability and compressive strength up to 45 days of age compared to those of conventional concrete. The obtain results indicate that the workability is increasing, the density and the compressive strength are decreasing up to 20wt% replacement ratio. Moreover, the compressive strength of WGP based concrete is lower than that of conventional concrete up to 28 days of age and becomes superior from 45 days age. The best obtain average values of workability and compressive strength are respectively 7.2cmand 30.25MPa up to 28 days of age for the case of BPV20. Thus, for its good pozzolanic characteristics and the influence on the properties of concrete, the glass powder obtained by basic grinding non-reusable glass debris can be used in the formulation of ecological concrete for common civil engineering applications.
