On Aggregate Grading is good concrete performance dependent on meeting grading limits? Specifying concrete mixtures with well-graded (WG) combined aggregates can be controversial. Advocates1-4 argue that such mixtures have optimized packing and minimal voids and therefore minimize the cementitious paste required for a given workability.

Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete.
characteristics and properties of aggregate in relation to the required application is required. Apparent relative density Relative density influences the choice of an aggregate for a specific application where concrete density is an important factor, eg concrete used for radiation shielding is made from high-density aggregate.
