Abstract

This paper study the effectiveness of waste material from industrial by-product as lightweight self-cured concrete. Waste material involved in this study is coal bottom ash, oil palm boiler clinker and hydrogel from diapers. Coal bottom ash (CBA) used as a fine aggregate replacement whilst oil palm clinker (OPBC) added into the concrete mixture as partial replacement of coarse aggregate in order to produce lightweight concrete. In addition, hydrogel from disposable diapers was acted as self-curing agent. Different percentage of CBA as the fine aggregate replacement in concrete was used with the constant value of OPBC as coarse aggregate replacement. The result shows that the concrete sample containing 100% replacement of CBA has the lightest density as compared to other samples. In terms of compressive strength, the sample containing 40% replacement of CBA has similar compressive strength to control sample with reduction of the density of 22% when compared to the control sample. It is concluded that the recycling of CBA and OPBC as replacement material in lightweight concrete has good potential and also processing of CBA and OPBC to develop nano-material are the future potential of CBA and OPBC research for energy efficiency building.
