The influence of different sandstone aggregates on the strength of the concrete was evaluated. According to the results obtained, subarkose–arkose, sublitharenite–litharenite and arkose aggregates which have clay cement caused approximately a 40–50% reduction in concrete strength when compared to subarkose, Cement, natural sand, crushed stone, and water are the four primary ingredients of concrete. Sand constitutes two thirds of the composition of concrete; every construction, from small to large, requires a huge amount of sand as demonstrated in Fig. 1.
