Sugarcane bagasse ash as a supplementary cementitious material in concrete to enhance the compressive strength and reduce the permeability and corrosion

In the present study, binary mixes of different proportions ranging from 5% to 30% replacement of cement by sugarcane bagasse ash (SCBA) which is an agricultural byproduct is investigated for compressive strength, economy, weight and permeability of the mix. It is observed that 15% replacement of SCBA is optimum considering the compressive strength, permeability, weight and economics of the mix. It further reduces the use of cement, which is one of the major sources of pollution in the environment (Andrew, 2018). The test results indicate that using sugarcane bagasse ash, the permeability of the mix has reduced to 'very low' as compared to the normal concrete mix M15, reducing the moisture ingress in concrete and corrosion. It further helps in reduction of CO2 emission, and the cause of corrosion also solving the problem of disposal of the agricultural waste generated which has no standard method of disposal (Maraveas, 2020).
