What is the maximum size of a sieve that the below-grade concrete floor's base course must pass through?

1 inch
2 inches
3 inches
4 inches

The correct answer is: 3 inches

The maximum size of a sieve that a below-grade concrete floor's base course must pass through is 3 inches. This requirement ensures that the aggregate used in the concrete is appropriately sized for effective compaction and minimal voids. Properly sized aggregates contribute to the strength and stability of the concrete slab, reducing the risk of settlement or cracking in the future. Allowing larger aggregates would interfere with the mix's workability, hydration, and overall performance, particularly in below-grade applications where moisture and environmental conditions can impact the concrete's durability. Therefore, adhering to the specification of a maximum aggregate size of 3 inches helps maintain the integrity and functional performance of the concrete floor in below-grade settings.
