Aggregate Crushing Value Test -Determine Aggregate ...

Procedure of Aggregate Crushing Value Test Put the cylinder in position on the base plate and weigh it (W). Put the sample in 3 layers, each layer being subjected to 25 strokes using the tamping rod. Level the surface of aggregate carefully and insert the plunger so that it rests horizontally ...

Aggregate Crushing Value Test – Determine Aggregate ...

The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road …

Aggregate Crushing Strength Test - Online CivilForum

AGGREGATE CRUSHING STRENGTH TEST Theory and Scope: This is one of the major Mechanical properties required in a road stone. The test evaluates the ability of the Aggregates used in road construction to withstand the stresses induced by moving vehicles in the form of crushing.

How to Find Aggregate Crushing Value and Its Test Procedure?

One of the test in which concrete material can fail is due to crushing under compressive stress. Aggregate crushing test is standardized by IS: 2386 part-IV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can …

PROPERTIES AND TESTING OF AGGREGATES FOR PAVEMENT …

Aug 25, 2016 · Crushing Strength Test on Aggregates Aggregate crushing value gives the Crushing strength of aggregate up to which it can bear the load without fail. To conduct crushing strength test we need compression testing machine, cylindrical measure, plunger and Isa sieves.

Effect of Aggregate Properties on the Crushing Strength of ...

With aggregates of "aggregate crushing value" 30 or higher, the result may be anomalous and in such cases the "10% fines value" should be determined and used instead. The standard aggregate crushing test is made on aggregate passing a 12.5 mm IS sieve and retained on 10 mm IS sieve. If required or if the standard size is not available other sizes up to 25 mm may be tested.

Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The " aggregate crushing value " give a relative measure of the resistance of

Compressive strength - Wikipedia

Introduction. The compressive strength of the material would correspond to the stress at the red point shown on the curve. In a compression test, there is a linear region where the material follows Hookes law. Hence, for this region, , where, this time, E refers to the Youngs Modulus for compression.

Aggregate: Mechanical Properties of Aggregate | Concrete ...

The aggregate shall be taken as in the case of crushing strength value test i.e., the aggregate should pass through 12.5 mm I.S. sieve and retained on 10 mm I.S. sieve. It should be oven dried at 100°C to 110°C for four hours and then air cooled before test.
