Abstract

Abstract: Cement is the primary raw material in any construction works, being an indispensable binding material. The production associate degreed consumption of cement is an index of its industrial development. However, excess production of cement pollutes the setting by emotional CO2 gas. So, it is necessary to exchange cement with alternative binding materials. In this study, one such trial is attempted using mineral admixtures like Fly ash, GGBS which are industrial waste byproducts. The concrete specimens are cast using, Fly ash, GGBS, and Metakaolin, with Alkaline liquid like Sodium silicate, and Sodium Hydroxide solution with 10 M, in the ratio of 1:1.5 and 1:2. Fibers such as steel fibers and polypropylene fibers are added with a 0–1.5% percentage to enhance the concrete properties. The moulds are cured under sunlight. The mechanical properties such as flexural strength, compressive strength, and split-tensile strength are performed along with durability tests to evaluate the optimized ratio of using mineral admixtures and fibers. The test results indicate that the combination of Metakaolin and GGBS can be used to develop environmentally friendly geopolymer concrete.
