Read MoreAggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test.
Crushing Strength Testing Machine Description. Crushing Strength Testing Machine to a certain size in the sample (corrugated paper)within a circular formation, between the upper and lower clamp pressure, can bear the most energetically before the sample is.
Read MoreAggregate crushing value test is done the find the actual crushing value of aggregate. We Need to carry out this test, To find out how much resistance does the aggregate has against the surface abrasion under traffic. To find out how much resistance does the aggregate can withstand under the roller during construction. To determine the strength.
Aug 27, 2019 The values of aggregate crushing test agree in general with that of aggregate impact test. The crushing strength test is most significant as far as the conditions to which the aggregates is likely to be subjected in practice are concerned. The suitability of aggregate in the pavement layers is dependent upon the type of road construction.
Read MoreName of the experiment Aggregate Crushing value test. 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 an aggregate to crushing under gradually applied.
Aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS The apparatus of the aggregate crushing value.

Used to measure the strength of cylindrical rock specimens, which are subjected to triaxial compression.
Read MoreMar 28, 2021 Aggregate crushing test is done to find out the strength of aggregate which is the fundamental and essential components of concrete, flexible pavements, etc. than 70 to 80 per cent of the volume of concrete is aggregate. Aggregates are a very important component of concrete, so the quality really matters when it comes to aggregates.
Apr 26, 2018 Apparatus needed for finding the crushing strength of aggregate. Steel cylinder consisting of open ends at both sides having an internal diameter of 152mm. Cylindrical measure to measure the quantity of aggregates needed for the test. Tampering rod. A balance of capacity 3kg.
Read MoreJul 18, 2021 Crushing Value Test of Aggregates – Importance, Procedure, and Standard limits. The aggregate crushing value test on coarse aggregates gives a relative measure of an aggregate under a gradually applied compressive load. It is a numerical index of the strength of the aggregates. This test is helpful in the construction of roads and pavements.
1.The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place Aggregate Crushing Value = (B A) X 100 where A = weight of oven-dried sample B = weight in 'g' of fraction passing through 2.36 mm IS sieve. 6.Video Aggregate Crushing Value Test.
