Aggregate Crushing value depends on the shape of agg also Angular aggregates have a lower ACV than Irregular or rounded aggregates If we cut a core out of the same agg (Say in the quarry) and test for compressive strength will give a higher MPa value It can be considered as a concrete cylinder or UCS tested in lab So it is hard to corelate.Categories Most relevant lists of abbreviations for ACV (Aggregate Crushing Value).
The tests for Aggregate Crushing Value (ACV) and FACT (10 Fines Aggregate Crushing Test) measure the crushing strength of broken rock High abrasion resistance of aggregate is of less importance in concrete roadworks as it does not.Table 5 4 presents the statistical data of the LA abrasion mass loss aggregate crushing value (ACV) and aggregate impact value (AIV) obtained from 307 RA samples As expected the LA abrasion results suggest that the resistance to fragmentation of RA in descending order is RCA MRA and RMA However this trend is not clear in the case of AIV and ACV.
