Abstract
To reduce the carbon foot print from the production of Portland cement, there is requirement of creating other bond produced materials to make concrete. In this connection several efforts are put forward to develop binders with pozzolanic materials without cement, for this addition of chemicals is unavoidable to cause reactive, this work involves the use of fly ash, Recycled aggregate, alkaline activated fluids. Alkaline to binder ratio is 0.55 with exchange of 100% cement with fly ash and determine the strengths for 24hrs oven curing at temperature 60 °C and 28 days atmospheric curing. In this work waste materials fly ash and GGBFS are taken in the proportion of 70:30. The proportion of Sodium Silicate and Sodium Hydroxide is taken as 2.5 and the alkaline liquid to binder ratio is taken as 0.5. The molarity of the alkaline solution is taken as 8 M and 10 M. In this work, the coarse aggregates have been replaced by recycled aggregates for different proportions i.e. 0%, 25%, 50% and 100% the mechanical properties such as compressive strength, Split Tensile and Flexural Strength are evaluated.
