Construction aggregates derived from primary resources either by crushing of sound rock masses (crushed stone aggregates) or from naturally occurring unbound clastic sediments (natural sand and gravel aggregates) make the most voluminous mineral raw material exploited by humans nowadays (Fookes 1991; Přikryl The aggregate crushing process was carried out for 4–8 mm and 10–14 mm fractions using cone crushers of the 1044 type. Aggregate crushing was carried out in a Los Angeles drum, in accordance with the requirements of EN 1097-2:2020. The analysis showed that for grits of the 10–14 mm fraction, the lower values of the LA indices wereInfluence of Natural Aggregate Crushing Process on Crushing

The effect of coarse aggregate crushing on the mechanical properties of normal concrete and high-strength concrete during the uniaxial compression test is investigated. The findings reveal that: (1) The coarse aggregate crushing affects the concrete stress–strain curve. Increasing the content of crushable coarse aggregates can The aggregate crushing value test (ACV, BS 812-Part-110) is one of the test methods for determining the crushing resistance of the aggregates. Alvarado et al. and Reyes et al. concluded that the ACV test was practical, reproducible, and stable and is a pivotal method in the evaluation of aggregate crushing resistance.

The aggregate microstructure was characterized by XRD, SEM, and FTIR methods, and the toxic leaching analysis of aggregate was performed. The apparent density was 1973.1–2281.6 kg/m3, and the bulk crushing strength was 24.7–27.9 MPa. XRD measurements were performed to identify the phase composition using a Shimadzu Coarse Aggregate Crushing Waste (CACW) is a waste product that results from the primary crushing of aggregates.
