3.1 Mix design of Geopolymer Concrete The primary difference between geopolymer concrete and Portland cement concrete is the binder. To form geopolymer paste alkaline activator solution used to react with silicon and aluminium oxides which are present in fly ash and GGBS. This alkaline activator
Concrete mix design is the process of detrmining right proportions of cement, sand and aggregates for concrete to achieve target strength of concrete. The Advantages of concrete mix design is that it gives the right proportions of materials, thus making the concrete use economical in achieving required strength of structural members.
M20 is one of the grades of concrete .M20 is 20Mpa strength which is achieved after 28 days of curing.It is mostly used for residential buildings.It's nominal mix is (1:1.5:3) that means for one bag of cement we mix 1.5 bags of fine aggregate (san...
This research focuses on developing a mix design methodology for alkali-activated high-calcium fly ash concrete (AAHFAC). High-calcium fly ash (FA) from the Mae Moh power plant in northern Thailand was used as a starting material. Sodium hydroxide and sodium silicate were used as alkaline activator solutions (AAS). Many parameters, namely, NaOH concentration, alkaline activator solution-to-fly ...

This fly ash reacts with alkaline solution (e.g., NaOH) and Sodium Silicate (Na2SiO3) to form a gel which binds the fine and coarse aggregates. Since Geopolymer concrete is the emerging field, the guidelines from the Bureau of Indian Standards are yet to be formulated. An attempt has been made to find out an optimum mix for the Geopolymer concrete.
