dc.description.abstractUtilization of palm kernel shell (PKS) as alternative to conventional materials for the construction industry is desirable to promote sustainable development. The purpose of this study is to investigate the physical and mechanical properties of lightweight concrete produced with different sizes of PKS as coarse aggregate replacement. PKS of sizes 6, 8, 10, 12 mm and mixed of all the sizes were used to replace coarse aggregate in concrete which resulted in producing 60 cubes and 30 beams at 7, 14, 21 and 28 days of curing. The tests performed on the concrete specimens are dry density, compressive strength and flexural strength. It was revealed that the densities of the concrete specimens were all less than 2000 kg/m3 , which implies that the PKS concrete satisfied the requirement of lightweight concrete for structural application. The compressive strength of the 12 mm PKS concrete specimens at 28-day of curing was 10.2 MPa which was 4.0 ā€“ 15.9% better than the other PKS sizes concrete. The flexural strength of the 12 mm PKS concrete specimens at 28-day of curing was 2.85 MPa which was also 3.2 - 57.07% better than the other PKS sizes concrete. A recommendation for 12 mm PKS size is made to construction practitioners for lightweight concrete structural application
