ABSTRACT

Blended hydraulic cement is one of the broadly used technologies in construction by blending two or more types of cementitious materials. Nowadays the concrete industry in view of sustainable concrete practices, is looking forward for blending materials that can minimize solid waste disposal problems. This study investigates the effect of partial replacement of cement by glass powder and palm oil fuel ash on the properties of concrete. In recent years, glass powder and palm oil fuel ash is chosen to partially replace cement due to its pozzolanic properties. Experiment is carried out in M20 mix, for which optimum percentage of glass powder replacement is first fixed by replacing 5%, 10%, 15% and 20% of cement. Keeping the percentage of glass powder at this optimum, cement is further replaced by palm oil fuel ash at 10%, 20%, 30% and 40% of cement. Fresh and hardened properties of concrete are investigated. All the tests are giving positive results in concrete properties when the partial cement replacement is 30%.
