AGGREGATE CRUSHING 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.

Aggregates for Concrete
Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.

Effect of Aggregate Properties on the Crushing Strength of Concrete
This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test.

Figure 11d shows that the individual pellet strength of aggregate exhibits the same behavior as the bulk crushing strength. As the curing time increases, the single-ball strength of aggregate gradually increases. When the FA content is 20%, the aggregate strength can reach 5.68 MPa after 28 days. When the curing time is from 3 to 7 days, there is the fastest increase of the aggregate strength

7 Lab Tests on Aggregates to Make Better Concrete for Construction!
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low crushing value should be preferred. Lower crushing value means higher strength as it indicates a lower crushed fraction under load. This gives a longer service life and a more

Aggregate crushing test
Aggregate crushing test is done to find out the strength of aggregate which is the fundamental and essential components of concrete, flexible pavements, etc. More than 70 to 80 per cent of the volume of concrete is aggregate. Aggregates are a very important component of concrete, so the quality really matters when it comes to aggregates.

How to Determine the Aggregate Crushing Strength Value in Your Laboratory?
The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength. After sieving aggregates, a cylindrical measure is taken and find the empty weight of cylindrical measure(We).It is then filled with aggregates in three layers with 25 blows to each layer using a tamping rod.

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 cement concrete road. The aggregate whose crushing value is less than 40% can be used for wearing surface.

Concrete aggregates properties crushed by jaw and impact secondary crushing
Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing mechanisms.
