Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger.Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100 degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.
Aggregate Impact Values, (AIV’s), below 10 are regarded as strong, and AIV’s above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties.

(For other size range please refer to the IS code Table 1 for the required apparatus and the sieves) Apparatus. Compression testing Machine, Sieves 12.5, 10 and 2.36mm,.
The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provider. a relative measure of resistance to crushing under a gradually applied compressive load. To Standard Specification and Code of Practice for Construction of Concrete Roads, IRC 15, 1970,.Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place Aggregate Crushing Value = W B W A 100. Where, W A is weight of surface dry sample.
The value is higher when percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2. Aggregate crushing value 45 for aggregates used for concrete for non wearing surfaces and 25 for wearing surfaces like.Jul 14, 2018 AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from Its resistance to a slow compression load. The Indian Standard CODE IS 2386 (Part IV) – 1963 is used for.
The aggregate crushing value test result should not be than 30 for the concrete used for roads and pavements and, in case of other structures it may be permitted up to 45 . (c) Standard Guidelines for Crushing Test Followings are the standard guidelines for the crushing test on aggregates.Dec 19, 2014 CALCULATION • Aggregate crushing value = B A x 100 • The result should be recorded to the first decimal place and the mean of the two results reported. • To achieve a high quality of pavement, aggregate possessing low crushing value should be preferred. 8.
