With an advancement in technology and research, various studies have been carried out on traditional concrete mixes and proposes modifications in order to obtain better quality concrete having both mechanical and durability requirements. In this work, both mechanical properties and durability indices of supplementary cementitious material are considered. Agricultural and Industrial wastes like Sugarcane Bagasse Ash (SCBA) and Ground Granulated Blast Furnace Slag (GGBS) are utilized as supplementary cementitious materials. The main objective of the present study is to determine the effect of supplementary cementitious materials, its mechanical properties and durability indices upon alkali activator solution. To develop concrete containing sugarcane bagasse ash and ground granulated blast furnace slag using alkaline activator solution. This study is to determine the optimal replacement of OPC with SCM and compressive strength of different mix ratio concrete.

“…Original sugarcane bagasse ash has a greater carbon content and consists of more crystalline silica, which might cause problems when used as a pozzolan [14]. Heating or grinding, for example, could be other ways to increase the activation of silica in sugarcane bagasse ash [15][16][17][18][19]; on the other hand, it requires more energy to grind or burn into finer particles.…”

Sugarcane Bagasse Ash (SCBA) is one of the most common types of agricultural waste. By its availability and pozzolanic properties, sugarcane bagasse ash can be utilized as a partial replacement for cement in the production of sustainable concrete. This study experimentally investigated the impact of employing two types of sugarcane bagasse ash as a partial substitute for cement up to 30% on the compressive strength, flexural strength, and Young’s modulus of the concrete mixture. The first type of bagasse ash used was raw SCBA, which was used as it arrived from the plant, with the same characteristics, considering that it was exposed to a temperature of 600 °C in the boilers to generate energy. The second type of bagasse ash utilized, called processed SCBA, was produced by regrinding raw SCBA for an hour and then burning it again for two hours at a temperature of 600 °C. This was done to improve the pozzolanic activity and consequently the mechanical properties of the concrete mixture. The findings indicated that employing raw sugarcane bagasse ash had a detrimental effect on the mechanical characteristics of the concrete mixture but using processed sugarcane bagasse ash at a proportion of no more than 10% had a considerable effect on improving the properties of the concrete mixture. The utilization of processed SCBA up to 10% into the concrete mixture resulted in a 12%, 8%, and 8% increase in compressive strength, flexural strength, and Young’s modulus, respectively, compared to the normal concrete specimen. On the contrary, the inclusion of raw SCBA with varying content into the concrete mixture decreased compressive strength, flexural strength, and Young’s modulus by up to 50%, 30%, and 29%, respectively, compared to the normal concrete specimen. The experimental findings were validated by comparison with ACI predictions. ACI overestimated the flexural strength of SCBA concrete specimens, with a mean coefficient of difference between the ACI equation and experimental results of 22%, however, ACI underestimated the Young’s modulus of SCBA concrete specimens, with a mean coefficient of difference between the ACI equation and experimental results of −6%.
