In this study, we investigated the drying shrinkage and fracture energy of concrete with lime stone and other aggregates and their effect on the shear strength of RC beams. The results of material experiments showed that the use of the lime stone aggregate having large aggregate crushing value decreased the fracture energy and drying shrinkage

Fracture energy. From the plots of fracture energy, G IIF vs. percentage replacement of crushed stone fine aggregate in place of sand it is observed that, the fracture energy is maximum for 50% replacement, irrespective of (a/w) ratio. Thus, the fracture energy follows similar trend as cube compressive strength and split tensile strength.

sections focus on the effect of crushing conditions on fines generation. 3. Single particle crushing Crushers break rocks by fracture propagation in-duced by the applied compression and shear forces. The theoretical bases for fracture mechanics started in 1921 when Griffith related fracture propagation to pre-existing cracks or defects.

A dull, chalky and earthly fracture of a stone indicates signs of early future decay. Specific gravity: For a good building stone, its specific gravity should be greater than 2.7 or so. The heavy stones are more compact and less porous and they can be used for various engineering applications such as dams, weirs retiming walls, docks, harbours etc.
