Crushing Value Test of Aggregates – Importance, Procedure, and Standard limits. The aggregate crushing value test on coarse aggregates gives a relative measure of an aggregate under a gradually applied compressive load. It is a numerical index of the strength of the aggregates. This test is helpful in the construction of roads and pavements.
CALCULATION: • Aggregate crushing value = B/A x • The result should be recorded to the first decimal place and the mean of the two results reported. • To achieve a high quality of pavement, aggregate possessing low crushing value should be preferred. 8.
The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the "ten percent fines value…
The aggregate crushing value test is an important test of aggregates. It gives a numerical index of the strength of the aggregate and it is used for concrete in construction of roads and pavements.
