Aggregates serve as the fundamental granular framework within concrete structures, accounting for more than 60% of the total volume. Among them, coarse aggregates occupy approximately 45% of the volume, and their properties such as type, size, shape, and surface condition, profoundly influence the behavior of concrete [1].In particular, the maximum …

As the nominal maximum size of the aggregate is increased, the amount of water needed for the same workability is reduced. At the same cementitious material content, strength is therefore greater because the w/cm is lower. But in the high-strength range, over 40 MPa (5800 psi), …
