Lightweight Aggregate Concrete using Industrial Waste Palm Oil Clinker

Concrete is a major material used in the construction of buildings and structures in the world. Gravel and sand are the major ingredients of concrete but are non-renewable natural materials. Therefore, the utilisation of oil palm clinker (OPC), a solid waste generated from palm oil industry is proposed to replace natural aggregate in this research to reduce the demand for natural aggregates. Based on the results obtained, the study on the effect of percentage of clinker on strength and durability properties was drawn. According to ACI classification of light weight concrete only the 100 percentage replacement can achieve the definition of light weight concrete since its density less than 1900 kg/m3 and strength larger than 17 MPa. Eventually the 25 % replacement of the normal aggregate by the OPC will improve the strength and durability of the concrete.
