Abstract

Concrete is a suitable and popular construction material all over the world and cement is the most important constituent for its production. Due to continuous increasing of the cost of cement, the use of supplementary cementing materials such as industrial by-product (slag, fly ash, silica fume) and biogenic wastes (palm oil fuel ash, rice husk ash, ash from timber) have become significant in concrete industry. One of these important biogenic waste is the palm oil fuel ash (POFA) - generated as by-product from palm oil mills. The production of POFA increases every year, it is disposed for landfills without any return value and now becomes a burden. It contains a non-crystalline silicon dioxide with high specific surface area and high pozzolanic reactivity. Many researches have been conducted for the use of pozzolans, especially waste pozzolans- POFA, rice husk ash, silica fumeas a replacement of ordinary Portland cement (OPC). Test results regarding compressive strength and durability of concrete from these researches confirmed the use of POFA as a pozzolanic material for cement replacement in mortar and concrete. In this paper, a review on the strength of concrete as influenced by the use of POFA as partial replacement of cement in concrete has been presented. Based on the information available in literature on the utilization of POFA in blended concrete, the compressive strength of concrete as affected by the percent replacement and fineness of POFA in concrete is mainly discussed here. Advantages and disadvantages of POFA in concrete are also mentioned. Effective consumption of POFA as pozzolanic material in concrete, would decrease the cost of concrete production, could reduce negative environmental effect, and also would solve the landfill problem for the disposal of these wastes.
