Abstract

Construction has been most important human activity since ancient time. Concrete is widely used and trustworthy material for construction. Some of challenges in industry are global warming and insufficiency of construction material. One of the methods for replacing concrete constituents is the use of geo-polymer which helps in using very less quantity of cement in concrete. This project represents study on the mechanical properties of geopolymer concrete with various mixes. In this study, Geopolymer concrete is produced with fly ash and sodium hydroxide and sodium silicate is used as a binder. GGBS in proportions of increase of 10% to enhance various properties of concrete. For this project, the mix design is carried out for 14M concentration of sodium hydroxide. The specimen of size 150x150x150mm cubes, 150x300mm cylinders and 500x100x100mm prisms were casted and the specimens of geo-polymer concrete are cured at ambient temperature for 7 days, 14 days and 28 days. The cured specimens were then tested for compressive strength, split tensile strength and flexural strength respectively.

 

Keywords-Fly Ash, Ground Granulated Blast Slag, Geopolymer concrete, Sodium Hydroxide, Molarity.
