Investigating the performance of palm oil shell as a partial replacement of coarse aggregate in concrete.

Abstract

Aggregates provide volume at low cost, comprising 75 percent to 85 percent of the concrete. With increasing concern over the excessive exploitation of natural and quality aggregates, the aggregate produced from industrial wastes and agriculture wastes being viable new source for building material. The rising cost of construction material has also become a matter of concern. The reason for increase in cost is high demand of concrete and scarcity of raw material. Hence most of the researchers have focus on use of the waste materials in concrete according to their properties. This research was carried out to determine the possibilities of using Crushed Palm oil shells as aggregates in concrete. In this study, the physical properties of crushed palm oil shells as aggregates will be determined. Properties of concrete such as slump, density, compressive strength and tensile strength will be determined. In this study, Class 25 grade of concrete with a mix ratio of 1:1.5:3 (cement, sand, aggregates) will be produced by replacing crushed stones partial by crushed palm oil shell in percentages of 0%, 10%, 20%, 30%, 40% and 50%.36 cubes and 10 cylinders will be casted and their compressive strength will be tested after 7, 14 and 28 days and tensile strength will be determined at 28 days.
