| dc.description.abstract | Sustainable materials are the demand of the world today, as sustainability of material is very crucial for the progress of society. It is this very need, which initiates the quest for the suitable alternative to cement, with similar properties as cement. Since safe and effective disposal of industrial waste is also very crucial, alkali activated concrete seems an ideal solution to achieve both the objectives. The present scope of study involves a combination of fly ash and bottom ash to prepare alkali activated concrete at ambient curing. Sodium based alkaline activators were used during the investigation. Process parameters like source material variation, amount of alkaline admixture, variation of sodium silicate to sodium hydroxide ratio, variation of alkaline solution to cementitious material, admixture dosage and amount of extra water were investigated. Observations indicate that increase in bottom ash content from 40% to 60% lead to decrease in compressive strength of concrete on the other hand increase in the amount of Sodium Hydroxide activators from 10 M to 14 M lead to increase in compressive strength. Compressive strength increased from 30.5 to 33.3 MPa when alkaline ratio increased from 1.5 -2.5. | en_US |
