dc.description.abstractAlkali Activated Concrete (AAC) is a moderately new form of concrete that has gotten a lot of interest in recent decades owing to its environmental advantages and features. However, further research into the effects of various proportions of fly ash, ground granulated blast furnace slag (GGBS), and lime on the characteristics of calcium-based AAC is still needed. This work aims to provide detailed information about the characteristics of AAC with various concentrations of fly ash, GGBS, and lime in order to produce the best combinations for engineering applications. The alkali activators in this investigation are sodium hydroxide and calcium silicate. All concrete mixes are examined for workability, strength, and durability for knowing the impact of fly ash, GGBS, and lime on AAC performance. The results specify that the increase in dosage of GGBBS diminishes the workability. The accumulation of only lime and GGBS shows optimum strength and durability results. In this study further regression analysis has been carried out for predicting the strength of the AAC. The regression equation was developed using the response surface approach for reliably predicting experimental outcomes with an acceptable margin of error.
