The range of values given by Shetty 46 for some natural aggregates aggregate crushing value 1233 and aggregate impact value 1034 signify that natural aggregates are generally stronger and more shock-resistant than periwinkle shell and cockle shell.
Polished Stone Value Test Procedures And Equipment
The percentage mass of fines passing a 2.80mm BS test sieve formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than ...
Aggregate Mechanical Properties Of Aggregate Concrete
The aggregate shall be taken as in the case of crushing strength value test i.e., the aggregate should pass through 12.5 mm I.S. sieve and retained on 10 mm I.S. sieve. It should be oven dried at 100 C to 110 C for four hours and then air cooled before test.
Concrete Aggregates Function Properties
Crushing strength, impact value abrasion resistance, and elastic modulus of aggregate are interrelated properties that are greatly influenced by porosity. Aggregates from natural sources that are commonly used for making normal-weight concrete, are generally dense and strong therefore they are seldom a limiting factor to strength and elastic ...
