AGGREGATE CRUSHING VALUE - iricen.gov.in
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
DETERMINATION OF AGGREGATE CRUSHING VALUE
The aggregate crushing value gives a relative measure of the resistance of an 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.
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 Value Test - Civiconcepts
Calculation of Aggregate Crushing Value: Aggregate crushing value can be found by the following formula, “Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 2.36 mm IS Sieve divided by weight of aggregate sample taken for test” Aggregate crushing value = (W3 / W) or W3 / (W2 – W1)
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.

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
Aggregate Crushing Value Test - Significance & Test ...
The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.
Aggregate Crushing Value Test -Determine Aggregate ...
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. 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. Aggregate crushing value is a numerical index of the strength of the aggregate …
7.7 Aggregate Crushing Value and 10% Fines Value 7.7.1 ...
Calculate the Aggregate Crushing Value (ACV) expressed as a percentage to the first decimal place, of the mass of fines formed to the total mass of the test specimen …
METHOD B1 THE DETERMINATION OF THE AGGREGATE …
The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS
However, should this test be required to be performed BS ...
2.16 The aggregate crushing value is the ratio of the mass of fines formed by the crushing process to the total mass of the sample expressed as a percentage. Percentage fines = B/A x 100 (to the first decimal place) where A = The mass of the surface dry sample. B =The mass of the fraction passing the 2.36mm sieve after crushing.

Aggregate Crushing Value Test - Procedure and Result ... This testing method is known as an aggregate crushing value test. Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10 mm sieve.
