## The Role Of Aggregate On Concrete Strength

Excessive aggregate size will also make the concrete less workable. Chunks of aggregate may even end up protruding from the surface. As a general rule, your maximum aggregate size should never be greater than 1/3 the depth of the slab. As you can see, the aggregate you select plays a huge role in the performance of your concrete.

## What nominal maximum sizes of aggregate are …

In concrete slabs, the nominal maximum size should not exceed three-fourths of the minimum clear spacing of reinforcing bars or one-third of the section depth (ACI 302.1R). The commentary R26.4.2.1(a)(5) of ACI 318-19 states that the size limitations on aggregates are provided to facilitate placement of concrete around the reinforcement without honeycombing due to blockage by closely …
