Partial Replacement of Cement with Banana Fibre in Concrete

The effect of glass fibre on flexural strength, split-tensile strength and compressive strength was studied for different fibre content Banana trunk is cut layer by layer and bum in furnace with four different percentage compositions of banana fiber and fly ash. A total of 12 cubes with 150 mm x 150 mm x 150mm were used to determine the strength of concrete using banana fiber ash. All this specimens is cure for 7, 28 and 90 days using water curing method. 0.5% to 2% of banana fiber ash is added with fly ash 0-20% by weight. The materials use in my study is banana fiber ash, sand, cement, coarse aggregate, and water. The result analysis shows, the mix with 10% replacement of cement with fly ash achieved the maximum value of splitting tensile strength of 2.4 and 3.2 N/mm2 corresponding to 28 and 90 days of curing periods respectively. It was also concluded that specimen containing 10% replacement of cement with fly ash recorded increase in compressive strength of 27 N/mm2& 29 N/mm2 over the control specimen at 28 and 90 days of curing respectively. Specimens with 10% and 20% replacement of cement with fly ash achieved higher flexural strength than the plain concrete
