ABSTRACT
Incorporating wastes into concrete as alternative binder is on the increase. The research investigated the influence of milled glass when used to replace cement in the production of concrete. The glass was milled to a particle size finer than 600碌m and characterized using X-ray Fluorescence and X-Ray diffraction analysis. Glass powder was used to replace cement at varying level of percentages: 0, 5, 15 and 25%, respectively. Concrete samples were prepared using South Africa mix design method, adopting water-binder ratio of 0.47. The samples were put in water for curing at 7, 28 and 56 days, respectively. Results revealed that the waste glass powder is pozzolanic with a high content of Quartz. Water absorption increases with increasing Waste Glass Powder (WGP) with control samples showing the least water absorption of 6.38% at 56 days followed by 5% replacement with water absorption of 6.86%. The compressive and splitting tensile strengths decreased with increasing content of WGP. However, with 5% WGP content at 7 days of curing, the strengths surpassed the control and attained 99% strength of control sample at 56 days. In conclusion, 5% WGP exhibited the tendency of effective usage as supplementary cementitious material in concrete.
