MoreThe aggregate resistance to chrusing was tested by means of the Los Angeles abrasion test. During this testing, an aggregate is subjected to dynamic load by impact and abrasion.

MoreThe crushing resistance of SSA can provide an indication of its strength as an aggregate component and has been assessed, though only to a limited extent, using the 10% fines test, which measures the force needed to crush the material to the extent that 10% of the particles pass the 0.063-mm sieve, though this procedure is not strictly ...

More2019-3-11 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.

More2020-12-1 Based on the results obtained, the impact of aggregate crushing resistance on the mechanical properties of HPC was assessed. To this end, three properties were analyzed: modulus of elasticity; splitting tensile strength and compressive strength of HPCs in dependency on aggregate crushing resistance (Fig. 5, Fig. 6, Fig. 7).Download : Download high-res image
