The use of mineral aggregates is related to the increasing demand in construction, railway and road infrastructures. However, mineral aggregates can appear to be of variable quality, directly affecting their suitability for respective earthwork applications. Since the production of mineral aggregates should ensure the standardized, high …

The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred. Objectives: To …

Crushing is one of the most energy-consuming technological processes. The purpose of grinding is to achieve the desired grain size of mineral raw materials. The process of grinding consists of many factors, for example, the size and form of crushed grains, as well as their mutual arrangement inside the crushing machine chamber, the …

The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, a recommended method is described in appendix A. The method is not suitable for testing aggregates with an aggregate crushing value higher than 30, and in such cases the method for ten per …

Figure 1 shows the schematic image and apparatus of the impact value test. Aggregate crushing value is a percentage of the weight of the crushed aggregate obtained from the test where the specific ...

This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve.

Specifically, a modified dynamic crushing test (DCT) were firstly employed to simulate the stress characteristics of PAC gradation; then the single size range of aggregate (SSRA) in PAC gradation and two types of PAC gradations, including three sets of traditional and developed PAC gradations respectively, were selected to determine …
