Final answer:
The abrasive strength of concrete is most closely related to compressive strength.
Step-by-step explanation:
The abrasive strength of concrete is most closely related to compressive strength. Compressive strength is the ability of concrete to resist compressive forces, such as being crushed or squeezed. It is commonly measured in megapascals (MPa) and is an important factor in determining the durability and performance of concrete
Permeability, air entrainment, and cementitious ratio are also important properties of concrete, but they are not directly related to abrasive strength. Permeability refers to how easily water or other substances can pass through the concrete. Air entrainment is the inclusion of tiny air bubbles in the concrete, which can increase its resistance to freeze-thaw damage. Cementitious ratio is the ratio of cement to other materials in the concrete mix, and it affects the strength and workability of the concrete.
