TESTING OF AGGREGATE CRUSHING VALUE. Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased. It is tested in accordance with BS 812:110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing. The allowable range is 17- 41.
Since beginning, Admaterials has provided imported aggregate testing for the following tests as required by BCA. Petrographic Examination (ASTM C295), Alkali Silica Reactivity–Mortar Bar Method (ASTM C1260), Water Soluble Chloride Content (EN 1744-1, Clause 7), Acid Soluble Sulphate Content (EN 1744-1, Clause 12)
The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the "ten percent fines value" should be …

The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm. The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.

A In the case of manufactured sand, if the material finer than the No. 200 sieve consists of the dust of fracture, essentially free of clay or shale, these limits are permitted to be increased to 5 and 7%, respectively.. The soundness of fine aggregates can be determined by subjecting the material to five cycles of the soundness test. The weighted average loss cannot be greater than 10% when ...
Report the mean as the aggregate 10% fines value, unless the individual results differ by more than 10 kN or by more than 0.1 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the aggregate 10% fines value.

AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.
This test method is intended to serve as a rapid fieldcorrelation test. The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-size or plastic fines and dust in granular soils and fine aggregates that pass the 4.75-mm (No. 4) sieve. The term "sand equivalent" expresses the concept that most granular soils and some fine aggregates are ...

T 176 Standard Method of Test for Plastic Fines in Graded Aggregates and Soils by Use of Sand Equivalent Test6 3. Terminology 3.1 Definitions: 3.1.1 fine aggregate—aggregate passing the 9.5-mm (3⁄8-in.) sieve and almost entirely passing the 4.75-mm (No. 4) sieve and predominantly retained on the 75-µm (No. 200) sieve (see Terminology D 8).
SUMMARY OF TEST Individual aggregates of specific sieve sizes are tested for ratios of width to thickness, length to width, or length to thickness. The test is performed on a sample of coarse aggregate reduced from a representative field sample. The sample is sieved to separate each size larger than the 3/8 in. (9.5 mm) sieve.
testing fine aggregate, the test was modified as follows: A 700-g sample of sand was washed on a 75-µm sieve and oven dried. A representative oven-dry subsample of 500 ± 5 g was prepared and immersed in tap water at room temperature for 24 hr. Excess water was poured off and the sample placed in

Importance of Impact Test on Aggregates. The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.. The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.
The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
