By definition crushed stone is a construction aggregate. It is created by mining a suitable rock formation and then using a crusher to break down the stone into different sizes. Crushed stone differs from gravel in that gravel has a more rounded shape and is made by the natural processes of weathering and erosion.

Variation in the size of Aggregates changes the water demand, cement content, micro-cracking (strength) in concrete. It also effects pumpability, and durability of concrete. Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix,

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.

Jun 26, 2014· The interlocking between aggregate particles is better than rounded aggregate but not adequate to be used for high strength concrete and pavements subjected to tension. 3. Angular Aggregate. The aggregate with angular shape has the maximum percentage of void ranging from 38 to .
Angular Aggregates. ... In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. the size range of various coarse aggregates given below. Coarse aggregate: Size: Fine gravel. 4mm – 8mm. Medium gravel. 8mm – 16mm. Coarse gravel.
Driveways: Angular gravels are best as they are not easily displaced when driven over compared to a more rounded product that may develop ruts where wheels repeatedly cross. To avoid chippings being caught in tyre treads, we advise gravels graded 14mm or 20mm, with our granite, basalt & flint materials having a greater longevity due to their ...
