As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Scope of work in aggregate crushing value, quarry, aggregate, and different kinds of minerals.

Mar 30, 2021 Aggregate impact value = W2/ W1 *100. W2 – Weight of aggregate which passes through the IS sieve 2.36mm. W1 – Weight of oven-dried aggregate. For good quality aggregate, the impact value should not exceed 30% for concrete work and 45 % for base course.

Impact test - Determination of aggregate Impact value

Impact test - Determination of aggregate Impact value

Procedure of Aggregate Crushing Value. Take a sample of aggregates by sieving through 12.5mm and retained on 10mm. The aggregate shall be tested in dry surface conditions. If dried by heating, the period of drying shall not exceed 4 hours and temp shall be 100-110 deg C.

compressive load. With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous. Also aggregate sizes larger than 14 mm are not appropriate to the aggregate impact test. The standard aggregate impact test shall be made on aggregate passing a 14. mm BS test sieve and retained on a 10.0 mm BS test sieve.

The PI shall not exceed 12 or a value equal to 3 times the GM plus 10, whichever is the higher value. In the case of ... 10% fines aggregate crushing value (10% FACT), determined in accordance with TMH1 method B2, shall be not less than the appropriate value in table 3602/2, column 3. The Aggregate Crushed Value (ACV),

The fines can consist of crushed material, gravel, slag, or a blend and must have LAA loss not exceeding 45%. For microsurfacing, Michigan DOT allows using 2FA or 3FA fine gradations and the fine aggregate material must have an angularity index exceeding 4, a sand equivalent exceeding 60%, and LAA loss not exceeding 45% (Michigan DOT 2009).

Procedure of Aggregate Crushing Value Test. Put the cylinder in position on the base plate and weigh it (W). Put the sample in 3 layers, each layer being subjected to 25 strokes using the tamping rod. Care being taken in the case of weak materials not to break the particles and weigh it (W1). Level the surface of aggregate carefully and insert ...
