The effects of different sandstone aggregates on concrete

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.
