Sugarcane Bagasse Concrete Compressive and Tensile Strength Test Comparing with Coconut Fiber Concrete

Abstract

In this research work we used Sugarcane bagasse concrete (SCBC).Sugarcane bagasse easily found in sugar factories of Bangladesh. Some of them are used as fuel in sugar mills and rest of them are dumped into environment without any commercial return. The disposal of this material is causing environmental problems around the sugar factories. On the other hand, urbanization and industrialization is rapidly increasing in Bangladesh. So, the construction industry is rapidly expanding. Currently large amount of cement is needed for this construction industry. It will be increasing day by day. The study examined the potentiality of using classified Sugarcane bagasse concrete (SCBC) to replace some part of sand in concrete. In this study, bagasse sample was collected from roadside Hawker in Farmgate, Dhaka. After collecting the sugarcane bagasse, it was dried in sun for a week and then it burned in oven at 150°C to 200°C temperature for 24 hours. Sand was replaced by SCBC at different percentage of 0%, 2%, 5%, 10%, and 12%. Where the fibber length was 0, 3.5, 10, 42.5, 75 and 88.5 mm, water cement ratio was 0.45 and cement, sand and aggregate ratios was 1:1.5:3. The objective of this study was to determine the compressive and tensile strength. Strength was tested for 28 days. The test results was comparing with coconut fiber concrete from the previous research work. Results indicated that the replacement of sand by bagasse ash was better concrete properties. It also showed the economic advantages by using SCBA as a partial sand replacement material. Keywords: Sugarcane Bagasse, Sand replacement, Compressive strength, Tensile strength.
