بيت /crushing strength of newly pavad aggregates
The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch. Testing machines and extensometers for compression tests resemble those used for tension tests.

The adhered mortar makes bonding between the recycled aggregate and the new mortar (new interface, Figure 3) weaker, which leads to worse recycled concrete performance, affecting properties related to deformation (modulus of elasticity, drying shrinkage and creep), durability (water absorption and permeability) and, of course, mechanical behaviour (strength) (61, 64). Moreover, the adhered mortar .

The best aggregates to use for strength are crushed stone or crushed gravel. Crushed aggregate have irregular, angular particles that tend to interlock when compacted or consolidated. The crushed stone or crushed gravel aggregate make the asphalt or concrete mix somewhat difficult to place. To improve the workability, many mixes
