Jul 16, 2014· Aggregate impact value test gives an indication of aggregate’s toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value (%) Toughness Properties <10 Exceptionally tough / Strong 10 – 20 Very tough / Strong []

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.

The aggregates should therefore have sufficient toughness to resist their disintegration due to impact. This characteristic is measured by impact value test. The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure of Aggregate Impact Test

Aggregate Crushing value depends on the shape of agg also. Angular aggregates have a lower ACV, than Irregular or rounded aggregates.If we cut a core out of the same agg (Say in the quarry) and test for compressive strength, will give a higher MPa value. It can be considered as a concrete cylinder or UCS tested in lab. So it is hard to corelate

The mean of the two test values was used as the MR value for that specimen. All specimens were then tested for ITS (at 77°F ± 2°F) after 2 hr of dry or wet storage. The ITS was obtained using a Marshall testing machine (deformation rate of 2 in./min) with a testing head that was modified by the addition of half inch metal strips.

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

Aggregate Crushing Value Civil Engineering Portal. This test helps to determine the aggregate crushing value of coarse value of aggregate must higher than 3 but I see the normal test result for ACV is is % of original mass? i want to know the importance of impact value of coarse aggregate.

The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it.

Mechanical Properties of Recycled Aggregate Concrete at . The RCA at 0.255 W/B ratio had a crushing value that increased from 10.28% to 11.95%, which means the process of heating and crushing for removal of attached mortar causes an increment in crushing value, and the attached mortar at 0.255 W/B ratio itself may cause almost no increase in crushing value of this type of RCA.
