Geopolymer is a type of concrete that has become more popular in recent years due to the fact that is significantly more environmental friendly than standard concrete. Geopolymer Concrete is produced by reacting with high rich aluminate and silicate bearing materials using an alkaline activator solution. In this present work, the suitability of non-destructive method to find the compressive strength of geopolymer concrete will be analyzed. The comparison of the compressive strength with both destructive and non-destructive method is checked for M30, M40, and M50 grade of geopolymer concrete cured in an oven and in ambient temperature condition. The calibration curve and regression curve for all the grades of concrete for the obtained rebound number is plotted. The alkaline liquid used in this study for the geopolymerization is sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). Different molarities of sodium hydroxide solution (8M &10M) are used suitably to prepare different grades of concrete cubes. The compressive strength test of geopolymer concrete cubes of size 150×150×150mm is tested at the age of 28 days for the experimental analysis.
