MIX DESIGN OF FLY-ASH BASED GEOPOLYMER CONCRETE

2021-6-4  Abstract- Geopolymer is a new development in the world of concrete in which cement is totally replaced by pozzoloanic materials like fly ash and activated by highly alkaline solutions to act as a binder in the concrete mix. For the selection of suitable ingredients of geopolymer concrete to achieve desire strength at required workability, an experimental investigation has been carried out for the gradation of geopolymer concrete and a mix design procedure is proposed on the basis of quantity and fineness of fly ash, quantity of water, grading of fine aggregate, fine to total aggregate ratio. Sodium silicate solution with Na2O = 16.37 %, SiO2 = 34.35 % and H2O = 49.28 % and sodium hydroxide solution having 13M, 10M 15M concentration were obtained throughout the experiment. Water-to-geopolymer binder ratio of 0.40, alkaline solution-to-fly ash ratio of 0.35 and sodium silicate-to-sodium hydroxide ratio of 2.0 by mass were fixed on the basis of workability and cube compressive strength. Workability of geopolymer concrete

A DETAILED PROCEDURE OF MIX DESIGN FOR FLY ASH

mix design method for fly ash-based geopolymer concrete has been proposed in a different approach. Variable concrete densities, the effects of the ingredients’ specific gravities, contributions of air volume, flexibility to improve the workability of fresh concrete and the opportunity to use aggregates in their ‘as is’ condition were considered importantly for overcoming the main limitations of current design methods. Experimental results showed that the compressive strength of the fly ash-based geopolymer concrete
