Properties of Geopolymer Concrete for Split Tensile Strength of Cylinder with Different Molarities of NaOH.

Civil Engineering

It is necessary to activate the fly ash by using alkaline activators. At present study investigations sodium based activators are used. Sodium hydroxide solution having different molarity concentration is used and Sodium silicate solution with Na2O and SiO2 were maintained constant throughout the experimentation. Further Geopolymer technology is new technology in which pozzolanic material which is rich in silica and alumina is used and it is activated by alkaline activators. Alkaline solutions may be sodium based or potassium based. Generally sodium based solution is used from economy and availability point of view.The experimental paper presents the split tensile strength of cylider test results of geopolymer concrete with different molarities of sodium hydroxide with various ratio of sodium silicate solution. This adopted mix design of M30 grade of geopolymer concrete procedure is relevant to previously adopted experimental study adopted by S.V.Patankar et.al(2013) carried the research of binder ratio in the production of fly ash based geopolymer concrete. This existing cement concrete Mix Design was applied to Geopolymer Concrete as experimental study to identify the higher concrete split tensile strength of cylinder with different molarities of sodium hydroxide.
