Use of Durian Pectin, Rice Husk Ash (RHA) and Eggshell Powder (ESP) in Concrete

Abstract

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. Therefore, the use of alternative cement such as fly ashes is being boosted by the increasing focus on reducing carbon emissions and also increasing owing to the extensive use of green cement. The objective of this study is to identify the optimum ratio of durian pectin to rice husk ash and durian pectin to eggshell powder as partial replacement of cement. Compressive strength and water absorption test were carried out at concrete laboratory on hardened 150mm³ concrete cubes for 7, 14 and 28 days of curing. Concrete made with 5%, 7.5% and 10% were replaced with durian pectin, RHA and ESP by the weight of cement. The results show that the sample consist of 5% of durian pectin and 5% of RHA is the best ratio replacement of cement in concrete because it achieved a good result in workability (slump test), compressive strength and water absorption are 85mm, 27.5 N/mm² and 6.5% respectively.
