Aggregate Crushing Value Test - Cement Concrete
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 under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.
Aggregate Crushing Value Test -Determine …
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.
Aggregate Crushing Value - Civil Engineering
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm
Determination Of Aggregate Crushing Value
The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected.

How to Determine the Aggregate Crushing …
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. Aggregate crushing value= (W2 / W1) × 100
Concrete Crushing - an overview | ScienceDirect …
07.08.2010 · An analysis of the abrasive wear of concrete floors has revealed that high-intensity crushing is the chief mechanism of deterioration, and hence the concrete crushing strength is the relevant parameter determining wear resistance.280 Generally, the abrasion resistance of the coarse aggregate component is not related to the wear resistance of the concrete; rather, the properties of …
Compressive Strength Test of Concrete - Detailed …
As per IS 456, the individual compressive value of a concrete cube should not be less than 75% from its grade. Example - If the concrete grade is M20, then the individual crushing value should not be less than 15 N/Sqmm. The individual crushing value difference between the cube should not be greater than 15%.

Compressive strength of concrete is the Strength of hardened concrete measured by the compression test. The compression strength of concrete is a measure of the concretes ability to resist loads which tend to compress it. It is measured by crushing cylindrical concrete specimens in …
Concrete recycling - Wikipedia
Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...
