Strength Investigation of Fly Ash and GGBFS based Geopolymer Concrete

Concrete is the major adoptable and durable material which is used in the construction industry. In today's day to day fast life many infrastructures are developed and it is also necessary to develop more and more infrastructures. For infrastructures, concrete is most required material and cement is the general base binding material for preparing concrete. So cement is required in large quantity for developing infrastructures. During the production of cement, large number of carbon-di-oxide is emitted in atmosphere. Due to increase in demand of cement an alternative product for cement is required. To reduce the carbon-di-oxide emission in the environment and to reduce the demand of cement an alternative product of binding material by recycling of industrial waste is created called Geopolymer. The Geopolymer or Geopolymerisation or Geopolymer concrete is the best innovative concrete material which is produced by chemical process with industrial waste. General method of Geopolymer concrete is a homogeneous mixer of fly ash or steel waste (GGBS), fine aggregate, course aggregate and alkaline solutions. The industrial combustion waste fly ash and the steel plant waste (GGBS) are the base material for Geopolymer concrete. Alkaline solutions are prepared by mixing of silicate and hydroxide. By Geopolymer process of binding material the requirement of cement is reduced and emission of carbon-di-oxide in atmosphere will reduce. High volume replacement of industrial waste or slag for development of concrete saves a lot of natural resources and energy which reduces the manufacture of Portland cement.

In the present work, an attempt has been made to establish the mix proportion to Geopolymer Concrete by flyash with steel waste (GGBS). To study the compressive and tensile strength of Geopolymer Concrete and to prove that the new alternate concrete material is eco-friendly.
