Oct 19, 2018 BS 812 Part 110 Aggregate crushing value (ACV) Through our UKAS accredited testing laboratory and in accordance to BS 812 Part 110 we can undertake the method required to determine the aggregate crushing value. This test provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
Standard BS 812 110 Crushing Value The apparatus is to determine the resistance of aggregate to crushing under a gradually applied compressive load. It consists of cylinder, plunger, base plate, tamping rod and measuring container. Technical Specifications Model Number NL 1024 X 001 NL 1024 X 002 Approx. Weight 20 kg 8 kg.

Jan 04, 2014 Test Name Methods for determination of Aggregate Crushing Value (ACV) Code BS 812 Part 110, IS 2386. Definition of ACV Aggregate Crushing Value (ACV) gives an relative measure how the aggregate act under an gradually acting compressive load. Sieve Size ACV is applicable for aggregates passing 14.0 mm sieve and retained on 10.00 mm sieve. For other size fractions methods.
Observations and Calculations Calculate the aggregate impact value (AIV) expressed as a percentage to the first decimal place for each test specimen from the following equation 𝑀2 (𝐴𝐼𝑉) = 100 𝑀1 Where M 1 is the mass of the test specimen (in g) M 2 is the mass of the material passing the 2.36 mm test sieve (in.
Mar 28, 2021 Aggregate Crushing test (IS 2386(Part 4) 1963 BS 812–110 1990) Aggregate crushing test values indicates the strength of aggregate and hence it is very significant. Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads.

The impact test (BS 812-112, 1990), as in the case of the compaction test (BS 812-110, 1990),  for some natural aggregates – aggregate crushing value (12–33 ) and aggregate impact value (10–34 ) – signify that natural aggregates are generally stronger and shock-resistant than periwinkle shell and cockle shell.
