How To Crushing Aggregate

Aggregate crushing value, when determined in accordance with IS: 2386 (Part IV)-1963 shall not exceed 45 % for aggregate used for concrete other than for wearing Read more rubbles crushing to aggregate percentage calculation formula

(DOC) Aggregate crushing value Test Lab Report |

Theory: The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under gradually applied compressive load. It’s the percentage by weight of the crushed(finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and is a numerical index of the strength of the aggregate used in road construction.

METHOD B2 THE DETERMINATION OF THE 10 PER CENT FINES AGGREGATE CRUSHING VALUE

The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of -13,2+9,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve. 2 APPARATUS As in SABS Method 842. 3 METHOD 4

How to Find Aggregate Crushing Value and Its Test

Aggregate Crushing value is a measure of the strength of the aggregate. The strength of concrete largely depends upon the strength of aggregate. The aggregate should therefore have minimum crushing value. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.

Aggregate Crushing Value Test -Determine Aggregate

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 indies its strength. Lower crushing value is recommended for roads and pavements as it indies a lower crushed fraction under load and would give a longer service life and a more economical performance.
