Depletion of natural resources and emission of carbon dioxide is the major factors associated with cement production. This problem can be solved by Partial replacement of concrete ingredients with waste or natural materials like fly ash, GGBS, silica fume, wollastonite, and waste glass powder. Partially replacing cement with wollastonite and ground granulated blast furnace slag(GGBS) helps in reducing environmental pollution. Wollastonite is abundantly available in India’s Udaipur belt of Rajasthan state as a low-cost material. This present work has aimed to determine the influence of the wollastonite-GGBS (w-GGBS) combination on the mechanical and durability properties of M50-grade concrete. We study the strength properties of concrete with wollastonite (5%, 10%, 15%, 20%). The optimum percentage of wollastonite in concrete corresponding to maximum strength will be identified. Keeping this optimum percentage of wollastonite replacement as constant, cement is further replaced with mineral admixture such as GGBS(5%, 10%, 15%, 20%). Test results indicated that the replacement of 15% wollastonite with cement shows better results than the conventional mix. The maximum increase in strength was observed in a mix that consists of 15% wollastonite and 15% GGBS.
