The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1. 2) A straight metal tamping rod of circular cross-section 16mm diameter and 45 to 60
Aggregate test is a process of performing certain tests on aggregates, as it is one of the main components of concrete. it is necessary to have certain checks for the physical properties, quality, and suitability of aggregates for specific applications in construction projects. Different types of Aggregate tests are conducted in the laboratory and field based on project …
Aggregate crushing value is the measure of resistance of aggregate to crushing against gradually applied compressive load. This test is conducted to determine the crushing strength of aggregate.
The aggregate crushing value test is performed on coarse aggregates to determine their resistance to crushing under a gradually applied compressive load. This test measures the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. The aggregate crushing value ...
Step-4 : Weigh the container full of aggregate. Step-5 : Calculate the net mass of aggregate in the measuring cylinder to an accurate of 1 gram. This quantity of aggregate constitutes the test specimen. ... The values of aggregate crushing test agree in general with that of aggregate impact test. The crushing strength test is most significant ...
This test is conducted to determine the crushing strength of aggregate. This test helps to assess the suitability of aggregates for use in road construction and other applications where they are subjected to high compressive stresses. The specifications for this test are given in IS : 2386 Part IV 1963 mechanical properties. Procedure
Sampling of Aggregates Coarse aggregate passing 12.5mm IS sieve and retained on a10mm IS sieve are selected and heated at 100 to 110°C for 4 hours and cooled to room temperature.
