Deployment of Palmic Concrete Pavement Blocks in Light and Heavy Traffic Situations

摘要

The main objective of this research was to investigate the viability of deploying palmic concrete pavement blocks (PCPBs) in light and heavy traffic situations. The term "palmic concrete" refers to any concrete containing palm kernel shell and ordinary aggregates. In this study cemen t, fine aggregate, coarse aggregate and palm kernel shell (PKS) were used. It was observed that density and strengths of the PCPBs decreased as the PKS content increased. Although, the strengths of the PCPBs lowered as the percentage of PKS increased, compressive strengths of 30.00 N/mm 2 to 48.70 N/mm 2 which are satisfactory for light traffic and heavy traffic situations could be achieved if 0% to 30% PKS contents are used. A model was also developed to predict the density of PCPBs through laboratory analysis. The model is only capable of predicting the density of palmic concrete products if the water cement ratio, the curing age, the aggregates cement ratio and the curing condition used are within the tested range.
