Concrete is the most popular material used in the construction works in which cement is the main composite. The manufacturing of cement involves the emission of greenhouse gases into the atmosphere which are responsible for global warming. Hence the researches are currently focused on various materials to replace and reducing the cement utilization. Moreover, in this contribution the concrete Geo-polymer has been made with GGBS (granulated ground blast furnace) along with steel fibers mixing. GGBS is the by-product produced from steel industry. Steel fibers are added to increase the tensile strength of concrete. In this experimental investigation geo-polymer concrete containing GGBS and steel fiber (0.5%) with 8 Molar and 10 Molar alkaline activators are used. The ratio of these alkali activators is 1:2.5. The results showed that fiber can significantly enhance the Mechanical properties. The enhancement also increases with the increasing fiber volume fraction.

The utilization of recycled materials in concrete is attractive for decreasing the consumption &waste of natural resources. The geo-polymer will be inorganic binder materials that as developed as alternate to conventional cement binders for concrete field. The geo-polymer concrete (GPC) will be established with the use of source materials such as sodium silicate, flyash, & alkaline activator sodium hydroxide, &cured at elevated temperature. An attempt was made to create GPC utilizing inappropriate mix of industrial waste materials such as flyash, glass powder and aggregates, & ground granulated blast furnace slag (GGBS). In current work, effort has been made to survey the usage effect of glass powder as incomplete replacement of flyash (FA) and GGBS based GPC. The flyash in GPC was exchanged by glass powder in range of 5 to 20% with an increase of 5%. It is noticed that 10% replacement of FA by GP provided maximum 28 days strength. The simulation outcomes depicted that replacement of GP & FA by numerous GGBS percentages resulted in increment of split tensile, compressive, flexural strength of FA based GPC up to 15% and thereafter there will be a reduction in strength values. Therefore, the outcomes of strength experiments on GPC cubes cured &prepared at 600C temperature at 48 hours only specify the improve men attained consistent to nominated optimum replacement of FA by GGBS glass powder. Therefore, the main industrial wastes like GP, FA, &GGBS is discover to be possible in production of novel sustainable green construction material of reasonable good strength.
