Microstructure studies in concrete are unique techniques for understanding the morphological features of concrete. In this research work, four mixture of concrete has been prepared by replacement of normal cement with geopolymer in 0 %, 50%, 80% and 100% of different ratio with recycled aggregates. Both class of fly ash F and C has been used with an alkaline activator (NaOH and Na2SiO3).In each mixture, the alkaline liquid, sodium hydroxide (Noah), and sodium silicate were dependent on the amount of fly ash, while the ratio of NaOH to Na2SiO3 is maintained 2.5 for all concrete. After costing twelve cylinders 150mm x 300 mm and twelve 152.4 mm x 152.4 mm x 609.6 mm concrete beams were cured for 28 days ata normal temperature of 27°C water. The physical and chemical properties have beeninvestigated in this research. The SEM and XRF analysis of all samples has been compared with the controlled sample. Which all samples have been compared with a controlled sample, to identify the changing of compressive and flexural strength in each sample.
