What is the approximate average compressive strength of paving bricks?

• A. 2000 PSI
• B. 5000 PSI
• C. 7000 PSI
• D. 10000 PSI

Answer: (B)

Compressive strength is the load per unit area a paving brick can bear before it crushes. Paving bricks are made to carry traffic and foot loads, so they’re designed with a solid, mid-range strength. The typical average strength you’ll see for paving bricks is around five thousand pounds per square inch. This value balances durability with cost and fits the performance of common clay or concrete pavers used in driveways and walkways on a proper base. Some bricks can be stronger, but five thousand psi represents the common, practical average. Values around two thousand psi would be too weak for regular paving use, while ten thousand psi is more than what's usually needed for standard paving bricks.
