IIT KanpurAggregate crushing value test Step by Step Procedure ,The time (10 minutes) is started in the stopwatch. The crushed material is then transferred into the sieve of size 2.36 mm. Sieving is done now and the sample passing through the sieve is collected and weighed. The weight is recorded as W2. Aggregate Crushing Value (ACV) can be determined by using a simple formula: This test is repeated once orConcrete Strength Acceptance Criteria IS:4562000,Why acceptance criteria for cube crushing strength is necessary.is it necessary that the lab,value of any grade concrete should be higher than prescribed grade.i.e.M25 done at site and lab value fck+4 =29,why it is higher and why not 25 if concrete is same batch used @ site and for tested in lab.
The abrasion Test measures 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 SmallSize Coarse Aggregate by Abrasion and Impact in Los Angeles Machine.
