In the present investigation, strength development in ambient cured geo-polymer concrete using industrial by-products for sustainable development is studied. The materials considered are Fly Ash, Ground Granulated Blast Furnace Slag (GGBFS). Geo-polymer concrete is prepared without using any conventional cement. The experimental program involves casting of geopolymer concrete cubes and testing the same at different ages for compressive strength. The different parameters considered in the study are, the molarity of alkaline activator and the proportion of binder components. The results reveal that the geopolymer concrete develops the strength even at ambient conditions without any conventional curing. Strength increases with an increase in the quantity of GGBFS. It can be concluded that geopolymer concrete can emerge as an ecofriendly sustainable construction material with properties similar to OPC.read more

The effect of composition and temperature on the properties of fly ash- and kaolinite -based geopolymers
TL;DR: In this paper, the relationship between composition and temperature on the final chemical and physical properties of a geopolymer derived from waste materials is investigated and it is shown that the differences in reactivity of source materials, used during the synthesis of waste-based geopolymers, significantly affect the final properties of the material.
