High strength of bricks made up of POFA and fly ash as cement replacement

Palm Oil Fuel Ash (POFA) is known as the by-product from palm oil industry while fly ash is a by-product of coal-fired power stations which both are substituted for Ordinary Portland Cement (OPC). The plenty amount of these waste products creates an opportunity for researchers to discover the poten...

Civil engineering (General) Palm Oil Fuel Ash (POFA) is known as the by-product from palm oil industry while fly ash is a by-product of coal-fired power stations which both are substituted for Ordinary Portland Cement (OPC).

After collect POFA at mill, the raw POFA will undergo oven drying process at 100 degrees for 24 hours. Then, the POFA will sieve to remove fibre and large particle before burning process. Next, POFA will undergo burning process at 500 degrees by using kiln for 6 hours in two days. This process to eliminate the excessive carbon content that leads to decrease the mortar brick and concrete strength. The production of ultrafine sized POFA is conducted using a 25000-rpm electric grinder to grind POFA for 30 minutes. Samples of the grinded burned POFA are analyzed to check its particle size at D50 by using the Particle Size Analyzer.
