Strength of Sieved Only Oil Palm Ash Foamed Concrete

H. Awang and M. Z. Al-Mulali

Abstract—Oil palm ash (OPA) is a waste material produced by countries having a blooming palm oil industry. Increasing palm oil production, the quantities of OPA continue to increase. However, its utilisation remains minimal and most of it is disposed of in landfills, causing environmental hazards. This study investigated the strength of foamed concrete incorporating sieved only OPA as a partial cement replacement. A foamed concrete mix of 1 part binder and 2 parts filler with a plastic density of 1450 kg/m3 has been used. Cement is replaced by OPA at replacement levels of 25 to 65% by weight of binder. Compressive, tensile splitting and flexural strengths have been investigated at the ages of 7, 14, 28 and 56 days. A foamed concrete mix with a 25% OPA content showed superior strengths than those exhibited by the control mix, hence, producing a greener and cheaper foamed concrete.

Index Terms—Foamed concrete, OPA, strength.
