Evaluation of Geopolymer Concrete on Partial Replacement of Fine Aggregate by Crushed Stone Dust

Abstract

A huge amount of Carbon-di-Oxide (CO₂) is released during the production and use of Ordinary Portland cement (OPC), which leads to heavy pollution in the environment. To curb this, we need an alternative material to replace OPC in the concrete mixture. There are some types of binders that we can be used, instead of cement likewise Fly ash & Ground Granulated Blast Furnace Slag (GGBFS). These are industrial which are widely available in a huge quantity in and around the steel industries. Fly ash has been preferred more eco-friendly in comparison with OPC as the emission of CO₂ during its consumption is very less as compared to OPC. Geopolymers are the new generation green material which is produced by utilizing these industrial by-products likewise Fly ash with highly alkaline activator solution. Geopolymers show similar properties as of standard cement. In this paper properties of geopolymer concrete and test results have been discussed on the basis of our research work.
