Jun 11, 2015· Table given below shows the crushing strength of various stones. Due to non-uniformity of the material, usually a factor of safety of 10 is used to find the permissible stress in a stone. Hence even laterite can be used safely for a single storey building, because in such structures expected load can hardly give a stress of 0.15 N/mm 2 .
Tests on prepared rock samples are little used, but the average value of crushing strength of such samples is about 200 MPa, although many excellent aggregates range in strength down to 80 MPa.
