EVALUATION OF WASTE GLASS POWDER AS ADMIXTURE AND PARTIAL REPLACEMENT OF FINE AGGREGATE IN CONCRETE

Abstract

Cement is the third most energy intensive material after steel and aluminium produced in tones. Cement industry consumes raw materials rich in silica, alumina, iron and calcium. Therefore this industry has been actively involved in finding ways to use waste products in the manufacturing of cement both as secondary fuel and raw material. Since the demand in the concrete manufacturing is increasing day by day, the utilization of river sand as fine aggregate leads to exploitation of natural resources, lowering of water table, sinking of the bridge piers, etc. as a common treat. An attempt has been made in using crushed glass as fine aggregate in the replacement of river sand. The aim of the present work was to use glass powder as admixture in concrete and partial replacement of fine aggregate. In this present work use 10% and 20% waste glass powder used. And for partial replacement of fine aggregate 5, 10, 15 and 20% waste glass powder used for compressive strength.
