Aggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is: 2386 (part iv) – 1963. the apparatus used is cylindrical measure and plunger, compression testing machine, is sieves of sizes –, 10mm and procedure to determine aggregate crushing value i) the aggregates passing through
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 penetration. 150mm Aggregate Crushing Value Apparatus.

The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure. Cylinder, plunger and base plate are made from special alloy ...
3. Density. The density of crushed concrete aggregate is smaller than natural aggregate density. 4. Water Absorption. Water absorption of recycled aggregate is greater than of natural aggregate. It is one of the most significant properties that distinguish recycled aggregate from raw aggregates.

The results indied that whereas the rocklike shale in the unsoaked state met all the Ministry of Roads and Highways strength specifiions for road aggregates, it lost practically all its strength in the soaked state. Water absorption was 900% the specifiion upper limit.

Recycled aggregate comes primarily from PCC and AC from road rehabilitation and maintenance, demolition, and leftover batches of AC and PCC. After processing, the rocks retain bits of cement or asphalt. A roadway is built in several layers: pavement, base, and sometimes subbase. The pavement is the surface layer, and is made of PCC or AC.
