Take the aggregate out of cylinder and sieve them through 2.36 mm IS sieve. Weight this fraction passing through it to an accuracy of 0.1 gm. This fraction is a quantity of loss of material due to crushing. Note down the observations in the proforma then compute the aggregate crushing value.
Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.
DETERMINATION OF AGGREGATE CRUSHING VALUE 1. AIM 1) To determine the aggregate crushing value of coarse aggregates Sieve the material through 12.5 mm and 10.0 mm IS sieve. The aggregates passing The mean of the two results shall be reported to the nearest whole number as the ‘aggregate crushing value’ of the size of the material
Aug 11, 2020· The crushed material is then transferred into the sieve of size 2.36 mm. Sieving is done now and the sample passing through the sieve is collected and weighed. The weight is recorded as W2. Aggregate Crushing Value (ACV) can be determined by using a simple formula:
The graded coarse aggregate is defined by its nominal size i.e., 40 mm, 20 mm, 16 mm, 12.5 mm, etc. For example, a graded aggregate of nominal size 12.5 mm means an aggregate most of which passes the 12.5 mm IS Sieve. Because the aggregates are formed due to natural disintegration of rocks or by the artificial crushing of rock or gravel, they

Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.

Aggregates crushing Value = B / A x 100. B = Weight of Fraction passing 2.36 mm IS sieve. A = weight of Sample in Cylinder. Crushing value of aggregates indicates its strength.
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 from the following expression. (ACV) = 100 x M 2 / M 1 Where, M 1 is the mass of the test specimen in grammes. M 2 is the mass of the material passing the 2.36mm test sieve in grammes.
The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.
For example, a graded aggregate of nominal size 12.5 mm means an aggregate most of which passes the 12.5 mm IS Sieve. Because the aggregates are formed due to natural disintegration of rocks or by the artificial crushing of rock or gravel, they derive their many of the properties from the parent rocks.

The aggregates passing The mean of the two results shall be reported to the nearest whole number as the ‘aggregate crushing value’ of the size of the material
the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, there is another recommended method.

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 less than 30% can be used for
Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) 1963.

Effective Size of Aggregates. Effective size (in microns) is the maximum particle size of the smallest 10% of the aggregate or it is the sieve opening corresponding to 10% finer and is designated by the symbol D10. Uniformity Coefficient of Aggregates. This is the ratio of the maximum size of the smallest 60% to the effective size.
