The test conducted to know the compressive strength of aggregate is known as aggregates crushing value test. The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30 or higher.

Jun 18, 2020 Differences in bacterial community composition in dependence on clay content were pronounced in dry‐crushed microaggregates. If intact aggregate architectures are of interest for the isolation of soil structural units, the presented dry crushing method might provide an advantageous alternative that also better preserves bacterial diversity.
Dec 19, 2019 If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.

Aggregate Abrasion Value Polishing Stone. Introduction In 1950 increased traffic flows and higher speeds on trunk roads, together with concerns about road safety led to research into the relationship between road materials and skid-resistance. Research at the UK Road Research Laboratory showed a significant relationship between polishing of aggregates used in road surfaces and skid resistance.
