It was concluded that the resistance of conventional concrete mix 1 found to have highest, whereas the results of mix 2 found to be best as compared to mix 3 against static and impact loading.

摘要

The manuscript focused to study the influence of sugarcane bagasse ash (SCBA) on the strength properties of hardened concrete as a partial substitute for cement in concrete. The study involves a comprehensive analysis of their effects on the mechanical and durability properties of concrete with partial replacement of cement with SCBA at varying percentages to produce cost effective concrete. The SCBA with 5 (mix 2), 10 (mix 3), 15 (mix 4), and 20 (mix 5) by weight was partially replaced with cement were considered and compared with the conventional concrete, mix 1. During the experiment, a constant slump range of 130 to 150 mm was maintained. It was observed that the decrease in compressive strength for mix 2, mix 3, mix 4, and mix 5 which was 4.5, 9, 22, and 42.57% respectively, as compared to conventional concrete. The compressive strength of mix 2 and mix 3 found almost 50 MPa which is equivalent to the target strength, whereas same found to be on mix 4 and 5 are 40.4 and 31.6 MPa, respectively. Therefore, it was concluded that SCBA up to 10% suggested to use in the concrete applications. Further, the performance of concrete with SCBA in the reduced scale reinforced concrete beams under static and impact loading was studied. The results demonstrated that at 28 days of curing of beams, the resistance of reinforced beam of mix 1, 2, and 3 under static loading found to be 22, 20, and 18 kN, whereas the same found to be 87, 73, and 65 kN, respectively, in the case of impact load. It was concluded that the resistance of conventional concrete mix 1 found to have highest, whereas the results of mix 2 found to be best as compared to mix 3 against static and impact loading.
