ABSTRACT
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 palm oil clinker (POC), a
solid waste generated from palm oil industry is proposed to replace natural
aggregate in this research to reduce the demand for natural aggregates. One mix
of ordinary concrete as control concrete; while four mix proportions of oil
palm clinker concrete were obtained by replacing 25%, 50%, 75%, and 100% of
gravel and sand of control concrete with coarse and fine oil palm clinker
respectively by volume, with same cement content and water cement ratio.
Compressive strength test was carried out of concretes with different percentages
of oil palm clinker; whereas water absorption tests according to respective standard, were carried out to
determine the durability properties of various mixes. 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 is
less than 1,900 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.
