Objective Aggregate Crushing Value Test- Objective Aggregate Crushing Value Test. For the aggregate crushing value test an aggregate sample passing through 125 mm is sieve and retained on 10mm is sieve is selected and dried to a temperature of 105 c to 110 c then cooled to room temperature to fill the cylindrical measure mould about 65.
1. objective. The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.

Jan 06, 2019 Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is suggested by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in …
The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
May 06, 2019 After each test, the needle should be disengaged, wiped with benzene, and dried. The amount of penetration is recorded as shown in Fig. 2. The main value of the three measurements is reported is the penetration test. The accuracy of the test depends upon pouring temperature, size of the needle, the weight placed on the needle, and test temperature.
