The principal laboratory aggregate tests include aggregate crushing tests, aggregate impact tests, aggregate abrasion resistance test, aggregate water absorption, specific gravity, and density...
Crushing Test of Aggregates. This test is done to find the strength of aggregates. The test procedure involves the following steps. The aggregate specimen is weighed (W1). The specimen is filled in a cylindrical mold of diameter in three layers with each layer being subjected to 25 blows. A plunger of diameter 15cm is placed on the top ...
Aggregate crushing value test Step by Step Procedure . The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is .
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top. Get a quote; figure of aggregate .
The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provider. a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred. Apparatus The apparatus for the standard aggregate .

Crushing Value Test (IS: 2386 (Part IV)) The material for the test should consist of aggregate passing mm sieve and retained on 10 mm sieve. For other sizes, the materials are separated on the appropriate sieves given in Table . Note: About 6500 g of natural aggregate is required to provide samples for the 150 mm cylinder, or about 1000 g ...
Mechanical Properties of Aggregates Aggregate Crushing Value Test (BS:812, part 3) Procedure • The material to be tested should pass a mm (1/2 in.) sieve and be retained on a 10 mm (3/8 in.) sieve. • Dry the sample in an oven at 100110 0 C for four hours. • Place the sample in a standard cylindrical mould and tamp it. • Put a plunger on the top of the .
· In the crushing value test, a loading mold with a diameter of 150 mm was filled with aggregates in three layers and was tamped evenly 25 times with a metal rod to level the surface. The loading rate was kN/s, and the load was 400 kN. After loading for 5 sec under 400 kN, the crushed aggregates were sieved with a standard sieve.
