· Principle of the Test: To produce the abrasive action by use of standard steel balls which when mixed with the aggregate and rotated in a drum for specific number of revolution cause impact on aggregate. The %age wear due to rubbing with steel balls is determined and is known as abrasion value. Prepare the sample by the portion of an aggregate ...

aggregate crushing value test report. An aggregate specimen is compacted into a steel cylinder fitted with a nofriction plunger. The specimen is then loaded via the plunger. The load crushes the aggregate to an extent depending on the crushing resistance of the material. It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate .

Mechanical Properties of Aggregates Aggregate Crushing Value Test Discussion • There is no explicit relation between the aggregate crushing value and its compressive strength but, in general, the crushing value is greater for a lower compressive strength. BS 812: Part 3 specifies a maximum limit of 30 for aggregates used in structural concrete and 40 on aggregates used in lean concrete.

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with onethird 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.

(Alan) Impact value of an aggregate is the percentage loss of weight particles sieve by the appliion of load by means of 15 blows of standard hammer and drop,under specified test condition. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from their resistance to a slowly applied ...

Discussion There should be included a brief discussion in which attention is drawn to the silent facts shown by the tables and diagrams. The test results should be compared with the standard values and conclusion should be drawn. Building Materials Laboratory Manual Fall 2007 2008 Prepared by: B. J. Farid 2 Reducing Field Sample of Aggregate to Test Sample ASTM C 702, D7 5 Purpose: To obtain ...

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. Read More ; Aggregate 10 Fines .

Aggregate Crushing Value Test Report. 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 ovendried sample b = weight in 'g' of fraction passing through aggregate crushing value test.

Conclusion Aggregate Crushing Value Test. Conclusion Of Aggregate Crushing Value Ore Processing. Aggregate Crushing Value Conclusion. 201055 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.

Procedure of Aggregate Impact Test. The test sample consists of aggregates sized mm mm. Aggregates may be dried by heating at 100110° C for a period of 4 hours and cooled. (i) Sieve the material through mm and IS sieves. The aggregates passing through sieve and retained on sieve comprises the test material.

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. Required Fig. 1: Balance Balance should be accurate upto 1 gm. Fig. 2: Sieve ...
