Abstract

The study deliberates on the incorporation of Microwave Incinerator Rice Husk Ash (MIRHA), Pulverized Fly Ash (PFA) and Silica Fume as a multiple binders to produce concrete. The mixes incorporating 5%, 7.5% and 10% MIRHA added with 10% PFA and 8% Silica Fume was prepared. The project objectives were to identify the optimum concrete mix proportion of binders containing Microwave Incinerated Rice Husk Ash (MIRHA), Pulverized Fly Ash and Silica Fume as concrete replacement material and also to establish the effect of MIRHA, PFA and Silica Fume on concrete properties. From the research that had been done, it's proved that 1 tons of Ordinary Portland Cement produces 1 tons of Carbon Dioxide (C02) emission. Beside that the usage of Portland cement can cause the environmental impacts at all stages of process in the industry. These include emissions of airborne pollution in the form of dust, gases, noise and vibration when operating machinery and during blasting in quarries, consumption of large quantities of fuel during manufacture, release of CO2 from the raw materials during manufacture. Research also had proven that in Malaysia 100,000,000 tons of rice husks were thrown away as a waste product. By reusing it, this figure can be decrease; beside it also can decrease the usage of cement. It can be processed to be used as a binder in the concrete mix and also can reduce the pollutions. Several experiments had been determined to observe different properties of the concrete such as compression strength, surface hardness, Ultrasonic Pulse Velocity (UPV) and splitting tension test. From this project, it was observed that an addition of MIRHA 5 %, PFA 10 % and Silica Fume 8% gave the optimal mixtures to get an optimal strength of the concrete. The same proportion also gave the optimum result for the tensile strength of the concrete. The different was about 14 % stronger than the normal concrete.
