  • Abstract:
  • Concrete is always expected to be stronger and more durable than in the past while being cost and energy efficient. Moreover the major advantages that concrete possesses over the construction material have to be conserved. So, the need for improving the performance of concrete and concern for the environment impact arising from the continually increasing demand for concrete has lead the growing use of an alternative material components. In this project, the characteristics of concrete by employing Coconut Shell Ash (CSA) and Rice Husk Ash (RHA) as a partial replacement for regular Portland cement (OPC) was experimentally investigated. Workability, Density of concrete and characteristics like compressive strength, Splitting tensile strength, flexural strength, Impact resistance and Modulus of elasticity were assessed and compared with the conventional concrete. Finally, the conventional concrete and Concrete with CSA and RHA respectively, two concrete mixtures were used. Compressive strength increases as CSA and RHA replacement increases and provides Satisfactory result up to 15% CSA and RHA replacement. This experimental study demonstrates that adding CSA and RHA at a replacement rate of 15% improves the workability and mechanical characteristics of both the conventional concrete and CSA and RHA
