In the article, based on the literature analysis, it was shown that the particle shape, size, quantity, and ratio between the fractions of coarse aggregate affect the workability of concrete mixtures, as well as the density, strength, and durability of concrete. This applies to all types of concrete mixtures, from self-compacting (SCC) to rigid (RCC). However, studies mainly focus on cube-shaped aggregates, while crushed ones, which has a flake-like shape, is widely used in concrete. In Ukraine, quartzite crushed stone with 25–55% flake particles are used in pavement concrete. It was found that flake particles significantly influence structure formation in concrete. If they are positioned horizontally during compaction, large air voids may form underneath, followed by smaller bubbles. This weakens the contact zone, reducing concrete density, flexural strength, and durability while increasing water absorption.
