Properties of mortar strength by using fine aggregate palm oil clinker with variation of water cement ratio

Abstract

Palm oil clinker (POC) is one of the waste material with a low cost that can found in the palm oil industry. POC has potential as a fine aggregate to replace the sand to produce mortar. This thesis was discusses about the impact of POC as a replacement material in a mortar mixture. POC will act as a substitute for sand in the production of mortar with water cement ratio variations diversity. The different of water cement ratio was used in this experiment to get the best result for compressive strength test. There was four different parameter to test the impact of the water cement ratio in the strength of mortar and the parameter is 0.5 , 0.55 , 0.6 , 0.65. Every type of parameter was test by using the different percentage replacement of POC. The percentage replacement of POC is 0%, 25%, 50%, 75%, 100%. The different percentage of POC with different variation of water cement content will produce different result of compressive strength. This thesis showed that the different percentage of POC with variation of water cement ratio can be used in the construction industry, especially for wall brick work and wall plastering work. The result was show that the POC can be used as a lightweight mortar and concrete.
