Researchon Self Compacting Geopolymer Concrete

The construction sector is suited for economy progress due to urbanization, industrialization, profitable growth and improved quality of life. The building material most commonly used is cement and its demand is increasing everyday that urged the industry to focus towards its production using alternative materials obtained from industrial by-products which may reduce the carbon foot print owing to the current global issues. Geopolymer concrete (GPC) has gain significance in this respect by using industrial by-product waste to replace cement and reduced carbon emission during its production. By alkali reaction of materials like alumina and silica it is produced. Because of the lack of compaction due to viscosity nature of GPC, a Self Compacting Geopolymer Concrete (SCGC) is used that compresses by its self weight. Industrial by-products like fly ash, Ground Granulated Blast Furnace Slag (GGBFS) and Silica Fume is utilized for generating SCGC. In this paper investigation on mechanical properties of SCGC under hot air curing and ambient curing is done. A variety of trial mixes for the fresh and hardened properties were tested. It was evident that the overall specimen subjected to test showed enhanced strength by increasing the content of GGBFS and fly ash.
