Abstract: This investigation reveals a critical experimental study in identifying the pictorial view of pore structure of concrete in different types of concretes comprising of class-F fly ash together with reinforcement over dissimilar fine aggregates like manufactured and river sands. Moreover, this investigation reports the analysis over dissimilar water curing conditions in finding out the pictorial view of pore structure of the concrete. For this experimentation, cement was partially replaced using fly ash and concrete mixes that were formed with 40%, 30% and 20% weights of cement and by using 16 mm diameter reinforcement. The performance analysis of this experiment was done by using X-ray diffraction spectrometry (XRD) and scanning electron microscopy (SEM). Moreover, this investigation recommends the use of concrete mix with 30% fly ash replacement in concrete.
