Therefore aggregate to be used in cement concrete should not be weaker than the strength of hardened cement paste. Determination of Crushing Strength of Aggregate: Material for the standard crushing test should pass through 12.5 mm I.S. sieve and retained on 10 mm I.S. sieve. The aggregate shall be thoroughly sieved on the above sieves before test.

Crushed Granite vs Pea Gravel: Pick the Right Material for

 · The selection of an aggregate is determined, in part, by the desired characteristics of the concrete. For example, the density of concrete is determined by the density of the aggregate. Soft, porous aggregates can result in weak concrete with low wear resistance, while using hard aggregates can make strong concrete with a high resistance to .

PROPERTIES OF AGGREGATES FOR CONCRETE

Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.
