Influence of Palm Oil Fuel Ash on Strength Properties of Concrete

Abstract

Cement which is highly responsible for hydration enthalpy and also the cost of cement which makes it uneconomical. The only way to deal with this kind of challenge is by introducing different products to replace certain amount of cement. An environmental friendly waste product produced from agricultural industries known as POFA (Palm-oil-fuel-ash) can be replaced with certain percentage of cement replacement in concrete and still attain similar strength such as conventional concrete. This paper intention is to focus changes on mechanical, strength properties of M30 grade concrete by using (POFA) palm-oil-fuel-ash. It is very much efficient in reducing cement expenses and also enhances the strength when engineered in technical aspects. When this agro waste palm oil ash is added, very less quantity of co2 emission takes place with reduction in liberation of heat from concrete. With the incorporation of palm oil fuel ash in various incremental order of (0, 10, 20, 30, 40) % replacement by cement in concrete, certain amount of change in behavior in concrete strength parameters namely compression strength, split tensile strength, and flexure strength is noted. M30 grade of concrete is considered while performing tests and analyzing, it shows that 10% replacement of cement by palm oil ash (POFA) gave high strength compared to conventional concrete. All the results generated are compared against control mix which gave an impression of improvement in (mechanical, strength) parameters of concrete in a positive way which helps balance the environment and also achieve sustainability of the concrete.
