Geopolymers are a type of inorganic polymer & light weight material that can be formed at room temperature with less energy losses by using industrial waste or by-products as source materials to form a solid binder. Geopolymer concrete is manufactured from utilization of waste material from industrial waste such as fly ash. Geopolymer concrete is a type of by which we can be used in applications to fully or partially replace OPC with environmental and technical alternative to Ordinary Portland Cement (OPC) based concrete. In the manufacture industry the creation of Portland cement causes the secretion of air pollutants which results in environmental contamination. It reduces 80 - 90% CO2 emissions. Coconuts fiber is collected from temples & shops and it is burn in open air then the ash obtained by coconut fiber ash is passed through 150 micron sieve. And then replacement of class f fly ash by coconut fiber fly ash from 0%, to 25 %. The color of fly ash may vary from tan to dark grey, depending upon the chemical and mineral constituents. The other characteristics of fly ash which are benefits, & its main aim to reduce carbon dioxide up to 80-90% and improved resistance to fire, impermeable and aggressive chemicals. Fly ash plays a vital role in Geopolymer concrete, and class f fly ash is used in construction purposes which contain 10% of lime also to replace the use of conventional ordinary Portland cement. To activate the substance in fly ash, sodium hydroxide solution and sodium silicate solution was used in combination.

IndexTerms- geopolymer, Coconut fiber, fly ash, sodium hydroxide.
