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

More2021-7-12 The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously. So the aggregate used for road construction should be able to sustain that motion pressure.

More2016-12-15 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
