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.

Calculate Aggregate Crushing Value. 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 = W B W .
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 ...
When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source: IS 2386(Part 4):1963) The aggregates crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. The principal mechanical property of aggregate required in any construction is (i) satisfactory resistance to ...
Aggregate Crushing Value test helps to determine the aggregate crushing value of coarse aggregates according to BS 812, Part 110:1990. These values are shown in table ; aggregate crushing value of the discarded aggregate is (%) while the natural aggregate is (%) which implies that the discarded aggregate has lower strength than the natural aggregate. Aggregate Impact Value ...
Title Aggregate Crushing Value Introduction Level 1 laboratory activity refers to condition where the problem and ways means are guided and given to the students. However the answers to the assignment are left to the students to solve using the group creativity and innovativeness. The activity is hoping to slowly introduce and incules independent learning amongst students .

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 .
i. Aggregate Crushing Value(ACV) Standard Test Method and Specifiion used: BS 812:Part 3:1975, BS 882:1992(). Test results obtained from aggregate crushing value test are summarized in Table10: Table 9Aggregate crushing value results Statistics (%) Range 1741 Mode 24 Specified maximum 25 for heavy duty concrete finishes
· Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, steploading compression tests were conducted on the mixtures of PA13 and a control asphalt mixture AC13, respectively.

Aggregate Crushing Value Ref : IS : 2386 (Part IV) Purpose : To determine the crushing value of aggregates. Significance : The aggregate ...
The aggregate impact value can be determined for bulk aggregate. BS:812112: 1990 provides full details for the toughness test. These tests will be related to the crushing value of aggregate. The tested aggregate can be surface dray or saturated. The size of the aggregate should be passing 14 mm and retaining on 10 mm. Then the aggregate sample is placed on the mold .
When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate.
