Concept and significance of the Aggregate crushing value test. 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 …

Ten percent fines value is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate. Fine aggregates are defined as those passing 2.36mm sieve. The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight […]

SBM321 – 2020 AGGREGATE CRUSHING VALUE AND 10% FACT VALUE SANS 3001-AG10:2012 INTRODUCTION The dry Aggregate Crushing Value and 10% FACT indicate the resistance of coarse aggregates to attrition. If the corresponding wet test is also done, it will give an indication of the durability of the aggregate.

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 is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate." Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.). ASTM C 33 ("Standard Specifications for Concrete Aggre-

Note 1: A procedure for testing coarse aggregate larger than 19.0 mm [3 / 4 in.] is covered in Test Method C535. Thus coarse aggregates with a maximum size between 19 mm [3 / 4 in.] and 37.5 mm [1 1 / 2 in.] may be tested by Test Method C535 or Test Method C131/C131M.

Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.

plus No. 4 material maybe prepared, by substituting the proper values in Eq. 3. This plot is shown as Curve A in Figure 1. It is apparent, however, that as the percentage of coarse aggregate Pc increases toward 100, the assumptions on which Eq. 3 is based become unrealistic and imprac tical.

Compared to the untreated coarse aggregate, the crushing values of microwave treated aggregates also showed an increasing trend. The crushing values of M2-T4, M3-T4, M4-T4 and M5-T4 aggregate were 16.2%, 17.4%, 18.9% and 22.5%, respectively. For M2-TX aggregate, its water absorption and crushing value index are smaller than untreated samples.

relationship between the aggregate sizes and the crushing values will however vary with the type0'[specimens tested. When non-standard sizes of aggregates are usnd for the crushing test, (i.e. aggregate ... ~Indian Roads Congress and IS) have specified that the aggregate crushing value of the coarse aggregates used for cement concrete pavement ...

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 …

1) To determine the aggregate crushing value of coarse aggregates 2) To assess suitability of aggregates for use in different types of road pavement 2. PRINCIPLE 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

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
