In the present study, 100% replacement of conventional ordinary Portland cement is made by using class F fly ash, Ground granulated blast furnace slag and catalytic liquids or AAS to prepare Geo-polymer concrete mixes. In our present study we evaluated strength characteristics of Geo polymer concrete by varying the percentage of glass fiber for M40 grade of concrete. The work has been done to structural specimen like cylinders, beams and cubes and evaluated compressive, split tensile strength, flexural strength for different binding material proportions and solution concentration. Glass fibers were added to the mix in the volume fractions of 0.01%, 0.02%, 0.03%, 0.04% volume of the concrete. Present study shall be a right step forward in reducing consumption of natural sand and consuming higher volumes of fly ash available in Chennai region together with fibers for sustainable and durable concrete. Keywords: geo-polymer concrete, fly ash, glass fibre compressive strength, split tensile strength. I. INTRODUCTION Concrete is one of the most widely used construction material. Portland cement production is a major contributor to carbon-di-oxide emissions .The global warming is caused by the emission of greenhouse gases, such as carbon-di-oxide, to the atmosphere by human activities. Among the greenhouse gases, carbon-di-oxide contributes about 65% of global warming. Many efforts are being made in order to reduce the use of Portland cement in concrete. These efforts include the utilization of supplementary cementing materials such as fly ash, silica fume, granulated blast furnace slag, rice-husk ash, Metakaolin and finding alternative binders to Portland cement. Geo-polymer is used as the binder, instead of cement paste, to produce concrete. The geo-polymer paste binds the loose coarse aggregates, fine aggregates and other unreacted materials together to form the geo- polymer concrete. The manufacture of geo-polymer concrete is carried out using the usual concrete technology methods. As in the Portland cement concrete, the aggregates occupy the largest volume, that is, approximately 75 to 80% by mass, in geo-polymer concrete. The silicon and the aluminum in the fly ash are activated by a combination of sodium hydroxide and sodium silicate solutions to form the geo-polymer paste that binds the aggregates. The production of one ton of cement emits approximately one ton carbon dioxide to the atmosphere, which leads to global warming conditions. So, one of the ways to produce environmentally friendly concrete is to reduce the use of Ordinary Portland Cement by replacing cement with by-product materials such as fly ash. One of the efforts to produce more environmentally friendly concrete is to replace the Portland cement in concrete with by-product materials such as fly ash. An effort to make environmentally friendly concrete is the development of inorganic alumina-silicate polymer, such as fly ash that are rich in silicon and aluminium called JASC: Journal of Applied Science and Computations Volume VI, Issue V, May/2019 ISSN NO: 1076-5131 Page No:135
