Abstract

In the last decades, the use of residue in civil construction, especially in addition to concrete, has been subject of many researches due to reduce the environmental pollution factors, it may lead several improvements of the concrete properties. Myanmar is one of the largest rice producing countries and per capita rice consumption is higher than that in any other countries. Considering that 20 of the grain is husk, and 20 of the husk after combustion is converted into ash. In this study, the chemical composition and physical properties of A.A.A Portland cement are tested. The rice husk ash RHA is obtained from Shwebo. And then, the ingredients of mortar and concrete such as sand and aggregate are tested. In this study, Ayeyarwaddy rivers sand is used. According to the silica content, the replacement percentage of RHA is considered as 0 , 5 , 10 , 15 and 20 by weight of cement. Finally, the compressive and tensile strength of mortar, and compressive strength of concrete are tested with various percentages of RHA. The results were compared to control sample and the viability of adding RHA to concrete is verified.
