·However the results of aggregate deformation tests under load are unknown According to Alexander [16] attention should be paid to the values of suitable aggregate crushing resistances which are granite 85 %; gravel 91 %; basalt 96 % The comparison shows that the negative correlation is between the strains of concretes Fig 9
·The stone crushing industry plays a vital role in reducing the particle sizes of rocks and ores and it is an important manufacturing area in rural regions involved in producing crushed stone of multiple sizes The two crushing surfaces are held together by springs so that they can separate under a load to allow any tough oversized material
·If column is short calculated load will be known as crushing load And load will be buckling or crippling load in case of long column This formula only gives the ultimate load but columns are design on safe load In order to get safe load divide ultimate load Load obtained from Rankin s Formula with factor of safety
·Deformational behavior is another important theme in investigating the mechanical properties of rock under cyclic loading For example it has been found that strain data can reflect the process of crack development in cyclic tests and that crack closure accompanies compressive deformation [] Liu et al and Chen et al [21 23] studied the types of deformation
