STUDY OF STRENGTH OF CONCRETE WITH PALM OIL FUEL ASH AS CEMENT REPLACEMENT

Rapid growth of infrastructure has led to the use of concrete almost everywhere, and one of the main products required in manufacturing concrete is cement, with the increase in the amount of cement used, heat of hydration increases which will lead to the formation of cracks in concrete accompanied by shrinkage effect. In order to control this, palm oil fuel ash, an agro waste which contains some amount of silica act as a pozzolanic material is being used as cement replacement and its strength is compared with conventional concrete of grade M25. Palm oil fuel ash which is obtained by burning palm fruit and dry leaves of palm oil tree in palm oil mills is also used to control heat of hydration effect on concrete, after pulverizing and making it into a fine powder.
