Review on the study of Fly ash based Geopolymer concrete

Civil Engineering

Large amount of carbon-dioxide emission takes place due to the increase in the production of cement. This results into greenhouse effect. In order to overcome this problem, many researchers have done experiments to find out optimum strength of concrete by replacing cement with fly ash and when it combine with alkaline solution which is known as a Geopolymer concrete. Self Compacting Geopolymer Concrete (SCGC) is a type of concreting execution and it does not require compaction. It is made by complete elimination of ordinary Portland cement content. SCGC needs more amount of fine aggregate than coarse aggregate compared to control mix. Geopolymer concrete were synthesized from fly ash, activated by combination of alkaline solution (sodium hydroxide and sodium silicate or potassium hydroxide and potassium silicate).
