ABSTRACT

Concrete has wide uses in structures, which makes it one of the most researched material of the 21st century. To meet the demand of the production of concrete, large quantity of Ordinary Portland Cement (OPC) is used as main binder material. Cement industry is believed to cause approximately 6% of global emissions of CO2. As a result, environmental degradation and protection of natural resources are becoming very important issues to be taken care of to promote sustainability in the construction industries. Utilization of waste materials such as industrial and agricultural wastes in the concrete production eventually reduces the environmental impact. Additions of supplementary cementitious materials (SCMs) during manufacture or directly through cement replacement at the building site can reduce the cement use and ultimately reduces environmental damage. This experimental work carried out on concrete specimen containing Rice husk silica powder as partial replacement with portland pozzolana cement. Adding different dosage of Rice husk silica powder (5%, 10%, 15% and 20%) by weight of portland pozzolana cement. Indian Standard cube and cylinder are prepared to measure compressive strength after 14days, 28days, and 56 days and split tensile strength after 56days of curing and compare this strength with M25 conventional concrete.
