Aggregate Crushing Value Test Crushing Value Test Of
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.Apr 13, 2020 (ii) Aggregate crushing value (ACV) test on aggregate ACV test (prescribed by BS 812 Part 110) provides useful information pertaining to the strength of aggregate The aggregate to be tested should pass a 1 2 in. sieve and should be retained on 3 8 in. sieve.
Applications Of Aggregate Crushing Test
Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test.Lightweight aggregates crushing resistance, Method 2. ( Aggregates-Rocks ) EN 13055-1 METHOD 2.
