Abstract
This research focuses on CSA (COCONUT SHELL ASH) Cement bricks, which are produced by partially substituting coconut shell ash for cement which is an agricultural waste. Cement is the primary component of cement bricks. Approximately 5% of global CO2 emissions are caused by the calcinations of CaCo₃ and fossil fuels during the cement production process. 5 and 10% replacement levels of cement with CSA were used to manufacture cement bricks. When put through several tests, including those for size, shape, structure, impact, soundness, hardness, and efflorescence, the CSA cement bricks created perform well. For replacement of 5% and 10 % of cement with CSA in CSA bricks the water absorption is found to be 11.5%, 12.8% and compressive strength is 8.3N/mm2, 9.4N/mm2 respectively. These results showed CSA bricks have slightly better performance compared to regular red bricks.
