REVIEW ON-GLASS FIBER GEOPOLYMER CONCRETE

Civil Engineering

Concrete is the most durable, versatile & reliable construction material in the construction industry. Concrete is used more than any other manmade material in the world. Second most consumable material after water in the world is concrete. Portland cement production is the second carbon di oxide generator industry after the automobile industries which cause pollution to atmosphere. Producing one tons of cement releases 0.87 tons of CO2. The global release of CO2 from all sources is estimated at 23 billion tons a year and the Portland cement production accounts for about 7% of total CO2 emissions. So finding any other alternative for cement was needed to reduce pollution done during production of cement. Innovative construction materials which produce by chemical action of inorganic molecules can replace cement in concrete known as Geopolymer concrete. The Previous study shows results of experimental program on mechanical properties such as compressive strength, flexural strength, and split tensile strength of Geopolymer concrete in two composite 90% fly ash, 10% lime with varying percentage of glass fiber. The effect of addition of glass fibers on the different mechanical properties of geopolymer concrete by replacing 10% fly ash by lime was studied. Based on literature studied it was observed that glass fiber geopolymer concrete have relative higher strength than plain geopolymer concrete & it neglect the limitation of heat curing due to replacing lime in concrete mix.
