Utilisation of Oil Palm Ash in Foamed Concrete

This study is a part of an on-going research examining the properties of foam concrete when replacing the cement with semi-processed Oil Palm Ash (OPA). Replacements range from 25% to 65% were used for a mix having the mix ratio of (1:2:0.45) and having the target density of 1300kg/m 3 . All mixes were tested for their strength using the compressive, splitting tensile and flexural strengths up to the age of 28 days. Results show that a 25% replacement level exhibited higher compressive and splitting tensile strength than that of the control mix at the age of 28 days. However, the same replacement level exhibited a close strength to that of the control mix when tested for the flexural strength at the same age.
