Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it …
With over 70 quarries we can supply a wide range of crushed rock materials. Our crushed rock includes granite, limestone, gritstone and basalt. Progressive stages of crushing and screening enable us to produce a range of aggregate sizes and we offer a range of polished stone value (PSV), including 70+PSV. Products offered: Crushed materials; Dusts
The role of rock and clast fabric in the physical performance of crushed-rock aggregate. Eng. Geol., 8: 267--285. Crushed rock aggregate responds in a rational and predictable manner to the two tests designed by British Standards for assessing aggregate strength, i.e., Aggregate Impact (IV) and Crushing Values (ACV).
