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), higher compressive strengths are usually obtained at a given w/cm with smaller nominal maximum-size aggregate (ACI 363R, ACI 214.4R). Similarly, higher flexural strength is obtained at a given w/cm with smaller nominal maximum size aggregate. Data from compression tests of concrete containing very large aggregates,

The effect of aggregate size on strength and

Increasing the granular composition of the aggregate increases the efficiency utilization of cement in concretes working in compression. At the same time, there is a reduction in deformation and an increase in Young's modulus and unit weight of the concrete. The tensile strength of the concrete is severely affected by increasing the size of the aggregate.
