The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and

The units are, therefore, force per unit area, which in the SI system is MN/m 2. Compressive strength is simply called 'strength' in the stone industry. Sometimes the compressive strength has been given for
Get PriceThe compressive strength of stone has been determined through 80 mm size cubes. It has been found that the compressive strength of granitoid-gneiss is greater when the load is parallel to the mineral bands. The compressive strength of stone masonry was studied through masonry prisms using 1∶4 and 1∶8 cement mortars.
