aggregate crushing value (acv) and ten percent fines value

These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger penetration. 150mm Aggregate Crushing Value Apparatus

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

May 17, 2019 Concept and significance of the Aggregate crushing value test. The aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under

3.4. Ten percent Fines Value (TFV) TFV test also measures the resistance of aggregate to crushing. It is also conducted on the 14 10mm fraction as for the ACV test, however, the TFV is preferred for weak aggregates in order to overcome the cushioning effect of excessive fines that might be produced by the ACV

aggregate crushing value test - procedure and result

aggregate crushing value test - procedure and result

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 should be determined

The strength of coarse aggregate as quantified by the aggregate crushing value (ACV) was found to be the most significant aggregate property for influencing bond strength. A regression model (based on the beam-end specimens test results) was developed to extrapolate the experimental development lengths as a function of fc1/4 and ACV
