Abstract

This paper discusses the results of a study on the use of palm oil clinker (POC) to replace coarse aggregate to produce medium lightweight concrete. Five types of concrete mixes containing palm oil fuel ash (POFA) varied from 5 % - 15 % were used as the partial cement replacement material. Compressive strength, density, workability and water permeability of this medium lightweight POFA concrete is determined to compare with the control mix (0 % POFA). It is found that the compressive strength of POFA mixes increased by an average of 8% - 14% compared to the control mix. The average coefficient of water permeability for medium lightweight POFA concrete is in the order of 10-11 m/s, which can classified as concrete with average quality. Study has shown that by utilizing POC and POFA, a good performance medium lightweight concrete can be produced.
