Sugarcane Bagasse Ash Concrete
This paper presents an extensive experimental study to investigate the possibility of using sugarcane bagasse ash (SCBA) as a partial replacement of cement in concretes. For this purpose, specimens containing 5, 10, and 15% SCBA in addition to a control specimen were prepared. To evaluate the mechanical properties of concrete specimens, compressive strength, tensile strength, impact resistance, workability and water absorption tests were performed. In addition to this, Resistance towards salts was tested by Chloride Penetration Test and Permeability Test was also conducted to check the suitability of SCBA for Road Construction. The results indicated that improvements in strength and impact resistance in concrete are observed as compared with the control sample when cement was replaced with bagasse ash at 5%. The 5% replacement also showed good results for impact strength and tensile strength, and had less Chloride Penetration as compared to the higher replacement. The Microstructure analysis of Normal Concrete and SCBA Concrete has also been analyzed using SEM(Scanning Electron Microscope) and XRD(X-ray Diffractometer).
