Abstract

Geopolymer concrete is a new type of concrete in which there is no use of cement in it as well as it is an eco-friendly concrete. In this project we are using hooked end steel fibre, coarse aggregate, fine aggregate along with Class-F fly ash. Sodium Hydroxide and Sodium Silicate are mixed together and alkaline solution is made and they are used as binding agent. Use of carbon dioxide is harmful for environment so we use geopolymer concrete. In this project we are testing the compressive, flexural and tensile strength of geopolymer concrete. M-40 grade of concrete is used in this project. We are taking three different ratios of steel fibre for testing. Percentage of steel fibre used is- 0%, 0.5%, and 0.75%. The testing of the concrete is done into three intervals that is for 7 days, 14 days, and 28 days. The end result is shown after 28 days and the optimum percentage of steel fibre is determined.
