ANALYSING THE IMPACT OF BANANA LEAF ASH ON THE MICRO, PHYSICAL, AND MECHANICAL CHARACTERISTICS OF CEMENT PASTE AND CONCRETE
Concrete has been the most widely used building material because of its many uses, strong compressive strength, and durability. Researchers are looking for substitute materials that could replace cement, either completely or partially, because of worries about sustainability. Cement in concrete has been partially replaced by banana leave ash. X-Ray Fluorescence was used to measure the oxide concentration after powdered banana leave ash and cement was examined using Fourier Transform Infrared Spectroscopy, X-Ray Diffraction Analysis, and X-Ray Fluorescence. The hydrated banana leaf ash and cement were evaluated by Fourier Transform Infrared Spectroscopy analysis after 28 days of curing. banana leave ash was substituted for OPC in several ratios (0, 5, 10, 15, and 20%) to create concrete cubes. A 100 x 100 x 100 mm mould was used to cast 45 cubes, which were then examined after 7, 14, and 28 days of curing in water. The density, aggregate impact and crushing values, standard consistency, sieve analysis, specific gravity, soundness, slump test, and compressive strength were all calculated. According to X-Ray Diffraction microanalysis, there are, respectively, 56%, 25%, 13%, and 6% of calcite, quartz, Sylvite, and magantite in the sample. The banana leave ash chemical composition is 27.37% SiO2, 2.21% Al2O3, and 1.41% Fe2O3, according to the X-Ray Fluorescence data. It indicates pozzolanic. BLA served as a retarder, delaying the initial and final setting times of OPC Grade 42.5 by 15% and 20%, respectively. The findings imply that banana leave ash might be used up to 10% in place of cement to achieve the desired compressive strength.
