PRODUCTION OF GEO-POLYMER CONCRETE FROM GGBS WITH DIFFERENT RATIOS OF FLY ASH

The paper deals with the influence of Ground Granulated Blast Furnace Slag (GGBS) and concentration of sodium hydroxide (NaOH) solution on the mechanical properties of the Geopolymer Concrete (GPC) with fly ash binder . Strength study of Geopolymer Concrete Incorporating flyash and GGBS with 10M Alkali Activator Solution. Geopolymer concrete is set up by utilizing soluble arrangement of sodium silicate and sodium hydroxide. This settledproportion is 2.5 and the concentration of sodium hydroxide is 10M. A summary of the extensive studies conducted on fly ashbased geopolymer concrete is presented. Test data are used to identify the effects of salient factors that influence the properties of the geopolymer concrete and to propose a simple method for the design of geopolymer concrete mixtures. Test data of various short-term properties of the geopolymer concrete and the results of the tests conducted on large-scale reinforced geopolymer concrete members show that geopolymer concrete is well-suited to manufacture precast concrete products that can be used in infrastructure developments. An experimental study on the strength properties of geopolymer concrete prepared using the ground granulated blast furnace slag and flyash is presented in the paper. The geopolymer concrete was initially prepared with ground granulated blast furnace slag as the primary binder instead of cement, was replaced with fly ash and blast furnace slag . The addition of more than 20 % of fly ash in geopolymer concrete retards the strength development, although such strength values are still above the target strength for of to 10 % and 5 % replacement levels.
