Effect of palm oil fuel ash (POFA) toward foam concrete compressive strength and microstructure

Malaysia is well known as the main crude palm oil producer and exporter in the world. Million tons of agro wastes such as palm oil fuel ash (POFA) is being produced every year with no commercial return on it. Due to the pozzolanic behavior possessed by POFA, it could be significance when the POFA is...

Civil engineering (General) Malaysia is well known as the main crude palm oil producer and exporter in the world. Million tons of agro wastes such as palm oil fuel ash (POFA) is being produced every year with no commercial return on it. Due to the pozzolanic behavior possessed by POFA, it could be significance when the POFA is being recycled and used in production of lightweight foamed concrete (LWFC). Thus, the aim of this research is to study the effects of POFA on engineering properties and microstructure of LFC with 1 600kg/m3 until 1800kg/rn 3 of density in terms of compressive strength, porosity, scanning electron microscope (SEM) and thermal gravimetric analysis (TGA).
