Abstract

The prime objective of the research is to find a sustainable means to reduce the consumption of non-renewable materials and utilize the waste materials as substitutes in concrete. According to the current study, clam seashells have been partially replaced for coarse aggregate. There is still a lack of exploration concerning its strength properties of concrete, when sea shell used as a replacement for coarse aggregate. Basalt Fiber has tangible malleable property; thus, it can be utilized as a fibre reinforcement material. An attempt has been carried out to study the potential utilization of basalt fiber, economically and effortlessly, found in India to create value-added products. This study aims to ascertain the mechanical properties of concrete, i.e., tensile, compressive and flexural capacity of concrete with the replacement of seashells and addition of basalt fibre. The current study reveals the effect on concrete by replacing the coarse aggregate using the seashell with a proportion of 0 %, 2.5 %, 5 %, 7.5 % 10 % and 12.5 %. The optimum percentage of compressive and tensile strength was found to be 10 % from the above replacements, and later, the basalt fibres of length 24 mm were added to the mix with 0 %, 0.25 %, 0.50 % & 0.75 % as addition and the strength parameters were evaluated, it is observed that considerable increase was there in mechanical properties.
