What is the required thickness for the Portland Cement Concrete (P.C.C.) layer over the aggregate base at the Wendy's Restaurant?

The required thickness for the Portland Cement Concrete (P.C.C.) layer over the aggregate base in a commercial setting like the Wendy's Restaurant is typically set at 5 inches. This specification is based on structural integrity considerations, load-bearing requirements, and environmental conditions that affect the longevity and performance of the concrete.

In commercial applications, a 5-inch thickness strikes a balance between durability and cost-effectiveness. It provides adequate support for vehicular traffic and the weight of the building, while also ensuring that the concrete has sufficient resilience against cracking and deformation over time.

Thicker layers, such as 6 or 7 inches, may be used in locations subject to extremely high loads or in specific areas where additional strength is needed, but for a standard fast-food restaurant like Wendy's, 5 inches is typically adequate. Choosing a thickness less than 5 inches, on the other hand, might compromise the strength and longevity of the concrete under normal operational conditions, making it unsuitable for the intended use.
