BS ISO 20290-3:2019 PDF

Scope: What is ISO 20290 ‑ 3 – Aggregates for concrete about? ISO 20290 is a series of international standards on concrete that discusses the test methods for mechanical and physical properties for aggregates for concrete. Concrete aggregates are composed of geological materials such as gravel, sand and crushed rock. ISO 20290 ‑ 3 is the third part of the ISO 20290 series, which gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve. For other size fractions, a recommended method is described in Annex A. The aggregate size fraction taken for this test can also be as per the relevant national standards. Who is ISO 20290 ‑
