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

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.
