Cement is one of the important materials in concrete mixture and use for building construction. High demand for cement usage due to the rapid development of construction in the country needs to be addressed. The objective of this study is to identify the workability and compressive strength of concrete at different level of replacement of cement. Cement was replaced with durian pectin and RHA by weight at 10%, 15% and 20%. Compressive strength and water absorption test were carried out on hardened 150mm x 150mm x 150mm concrete cubes after 7, 14 and 28 days of curing. The results revealed that the compressive strengths reduced as the percentage durian pectin and RHA increased in same ratio 5:5, 7.5:7.5 and 10:10. The sample consist of 5% of durian pectin and 5% of RHA is the optimum ratio replacement of cement in concrete with highest compressive strength 27.5 N/mm 2 , medium workability and water absorption 6%.
