Development of Self-compacting Concrete Incorporating Palm Oil Fuel Ash and Eggshell Powder as Partial Cement Replacement
Self-Compacting Concrete (SCC) is a type of concrete that can flow under its own weight and completely fill the formwork, even in the presence of congested reinforcement. Therefore, raw materials and natural resources are required in large quantities for SCC production. In order, to minimize the usage of the cement in the SCC, the use of agricultural wastes such as palm oil fuel ash (POFA) and eggshell powder (ESP) as partial cement replacement materials for an alternative preventive solution is suggested. In this research, 0, 2.5 and 5% ESP were combined with 5, 10 and 15% POFA as cement replacement in SCC. The influence of POFA and ESP on characteristics of SCC were examined by observation and comparison of the test outcomes with a control sample. Furthermore, the tests are conducted to study the modulus of elasticity (MOE), Poisson’s ratio, flexural strength and failure mode of SCC. The maximum modulus of elasticity of 5% POFA along with 2.5% ESP (5P 2.5E) was 31689 N/mm2, meanwhile, the highest flexural strength was 5.7 MPa with water-cement ratio of 0.4 at the 28 days water curing. Based on the outcomes, optimum replacement percentage of POFA and ESP was 5% POFA and 2.5% ESP exhibitions better behavior which is higher to the outcomes of a control sample of SCC.
