Sandstones vary in composition and consequently when used in concrete as aggregate may cause different concrete strengths. However, there are few data about correlating the effects of different sandstone aggregates. In this work we have highlighted some mechanical aspects concerning the use of different sandstones as concrete aggregate. The sandstone samples were first tested to determine their petrographic characteristics and aggregate properties. Then, concretes were prepared by using these aggregates, and fresh and hardened concrete properties were determined. 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, quartz sandstone and arkose aggregates which have carbonate cement, because these aggregates result in weaker bonding between aggregate and cement than others.
