Effects of Mechanical Properties on Unconventional Concrete where Coarse Aggregate is replaced by Palm Oil Clinker (POC)

This work is regarding the investigation on compressive strength, flexural strength and tensile strength of unconventional concrete using waste material. The material used in this project is palm oil clinker and it has been used to replace conventional coarse aggregate in concrete. The main objective of this research is to support the usage of waste product which helps to reduce the usage of conventional construction materials that are decreasing in terms or quantity and increasing in terms of price. The rate at which extinction of natural resources and pollution is increasing day by day is becoming alarming. The pollution of the environment in causing irreparable damage to the earth and it can be avoided by the usage waste materials which can be easily obtained. Other than that, factors affecting the mechanical properties of concrete are studied throughout the literature review. This has been done in order to combine information gained into this research and provide a better solution for palm oil clinker concrete. The various tests were performed on five different types of concrete mix with different percentage of palm oil clinker as a coarse aggregate replacement. This is to study the characteristic of palm oil clinker in concrete and as well as the changes that it makes in the strength of concrete. From the result obtained, due to its water absorbing characteristic, size and shape, palm oil clinker increase the bonding between aggregate by filling in the voids. Furthermore palm oil clinker enables internal curing which allows concrete strength to be higher. It has reduced the porosity of concrete, which means it has increased the strength of concrete. Lastly, palm oil clinker as coarse aggregate replacement in concrete has a major impact in the future of construction industry by drastically increasing the strength of concrete as well as the eradication of waste.
