Mechanical Performance of Lean Mortar by Using Waste Glass Powder as a Replacement of Cement

Abstract

Abstract: In present life, glass is used in construction, soft-drink bottles, medicinal bottles, automobiles, mirrors, windscreen, doors, windows, decorative items, tube lights, bulbs and other electronic gadgets etc. Glass has limited life period, so after completion of its utility period it is either stock piled or sent to landfills without being recycled. The aim of this work was to use the waste glass powder (WGP) as a partial replacement of cement for making mortar and compare its performance with normal cement mortar mix of ratio 1:3. In this research various types of waste coloured glasses and cleared glasses were used for making glass powder. Glass powder was obtained from grinding of waste glass. The main goal of this study is to demonstrate the possibility of using waste glass powder (WGP) as a partial replacement of cement which is used in mortar In this research work cement mortar cubes were used to understand the influence of the waste glass powder (WGP) on the compressive strength. A series of tests were conducted to study the effect of 0%, 5%, 10%, 15%, 20%, 25%, 30%, 35% and 40% replacement of cement by waste glass powder (WGP) on compressive strength test at 7 days and 28 days. Several test such as Consistency test, Initial and Final setting time, and soundness value of cement paste were also determined. And also the particle size effect was evaluated by using glass powder of size 75μm-90μm and glass powder of size less than 75μm. A total of 17 trial mixes were prepared for both sizes of glass powder.
