WORKABILITY AND COMPRESSIVE STRENGTH OF CONCRETE CONTAINING CRUSHED PALM OIL CLINKER AS PARTIAL FINE AGGREGATE REPLACEMENT

Abstract

Growing demand for river sand supply to cater to the need of expanding concrete industry has a negative impact on the river environment when the mining activity is carried out uncontrollably. Palm Oil Clinker (POC) is a waste material generated from the palm oil industry, which is thrown as environmental polluting waste. This experimental study aims to investigate the effect of POC as partial fine aggregate replacement material on the workability, compressive strength and water absorption of concrete. A total of six concrete mixes containing 0%, 10%, 20%, 30%, 40% and 50% POC as partial fine aggregate replacement were prepared. All specimens were subjected to water curing until the testing date. Compressive strength and water absorption tests were conducted at 28 days. Incorporation of 20% POC is able to produce concrete with targeted compressive strength. Success in utilising POC as partial fine aggregate replacement in concrete will reduce waste thrown at dumpsites.
