ABSTRACT
Cement is the most common binder used in the production of concrete/mortar. Still, there are problems associated with its production, such as high energy consumption, emission of carbon dioxide into the atmosphere, which causes global warming and greenhouse gas emission. For these reasons, a lot of effort has been made to look for a more environmentally friendly material that can partially replace cement. The production of mortar by which cement is partially replaced by sugarcane bagasse ash. This project investigated the comparative study on the properties of cement mortar produced using ground and unground sugarcane bagasse ash as a partial cement replacement. A standard mortar was produced, which served as control. The same mortar was produced by partially replacing the cement content with 0%, 5%, 10%, 15% and 20% USBA and GSBA. Results showed that the mortar samples with USBA and GSBA decreased compressive strength at 28days. Despite the decrease in the compressive strength, the target strength at 28days was achieved with partial replacement of up to 15%. After the comparative analysis between the USBA and GSBA, the results showed that the use of GSBA was identified to be more effective due to the fineness of the material as well the use of 15% USBA and GSBA was identified to be optimum and can be used in the production of mortar.
