Concrete Crushing - an overview ScienceDirect Topics
2010-8-7 An analysis of the abrasive wear of concrete floors has revealed that high-intensity crushing is the chief mechanism of deterioration, and hence the concrete crushing strength is the relevant parameter determining wear resistance. 280 Generally, the abrasion resistance of the coarse aggregate component is not related to the wear resistance of the concrete; rather, the properties of the mortar fraction are

CORRELATION BETWEEN AGGREGATE CRUSHING VALUE
2016-12-15 Aggregate Crushing Value (ACV) is an index of loss of coarse aggregate (CA) under sustained loading. However, ACV is not considered in concrete mix design according to ACI 211.1(ACI 211.1, 2009). In this paper effect of ACV of CA on compressive strength of concrete has been explored. Coarse Aggregate was collected from five different sources. Concrete mix design was conducted for target strengths of 3000, 4000 and 5000 psi according to ACI. Total 135Concrete cylinders were tested for compressive strength at 7, 14 and 28 days. ACV test for each type of Coarse aggregate was performed. Achieved strength Vs. ACV was plotted for each sample. It is observed that, compressive strength is inversely related to the ACV. Higher strength concrete is more dependent on ACV. To achieve target strength at 28 days, ACV should be less than 30, 29, and 28 for 3000 psi, 4000 psi and 5000 psi

2011-1-13 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

Concrete Crushing - an overview ScienceDirect Topics
2010-8-7 The desired concrete crushing failures shown in Figs. 1.24 and 1.25 can only be achieved if IC, CDC and PE debonding can be prevented from occurring before the design load to cause concrete crushing. However, this may not always be possible; in which case, it may be necessary to design for either IC or CDC debonding to occur at the design load so that concrete crushing will not occur.
