aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the mm (No. 4) sieve and predominantly retained on the 75 µm (No. 200) sieve is called fine aggregate or sand, and larger aggregate is called coarse aggregate.
The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of 13,2+9,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve.
test on road aggregates by crushing value test – Grinding ... The Aggregate Crushing Value provides a relative measure of the resistance of an The test subjects a coarse aggregate sample to abrasion, impact, and . a penetration test for evaluation of the mechanical strength of road .
aggregate crushing value test apparatus : lm17403 One of the major factors contributing to the quality of concrete is the quality of aggregates used therein. With the wide range of aggregates available, it is essential to select an aggregate that is suitable for a given application.
Feb 04, 2011· The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides 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.
Mar 06, 2019· 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.

crushing value of coarse aggregate Aggregate Crushing Value Test The Constructor. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than their crushing values. The impact test is widely used as an alternative to the crushing test.
Aggregate Crushing Value Test Determine Aggregate Crushing . May 5, 2010 Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
tested value with the appropriate specification (spec) limit. If sufficient testing data exists on a given aggregate quality property, the following methodology may be used to determine the frequency of test.
