The Effect of Particle Strength on the Compression of Crushed Aggregate The paper examines the variables controlling the compression of rock aggregates, and presents experimental data on the behaviour of limestone, dolerite and sandstone samples in size ranges up to 19.0 mm. The results suggest that while the initial void ratio of the aggregate determines the degree of compressive strain ...

Therefore, the strength variations of crushed limestone sand concrete after exposal to high temperature can be similarly treated as that of the natural sand concrete. Also it can be seen that the CLSC can use 0.5 power law equation to represent the relationship between compressive and splitting tensile strength before and after exposal to high ...

1997-11-1 · The strength of crushed limestone sand concrete was also investigated. It was shown that the fracture energy of concrete was little influenced by the type of fine aggregate. In addition, the fracture energy of crushed sand concrete was slightly higher than that of river sand concrete. This seems to be due to very fine sand (VFS) included in ...
