Three-Edge Bearing Test Determines Concrete Pipe Strength
The three-edge bearing test is a method that determines the strength of a concrete pipe by applying a specific load in a controlled environment such as the precast plant. Proper classification of the pipe is based on this test which follows the standards CSA A257 or ASTM C76. RELATED: Video: Pipe sample from 1842 shows durability of concrete pipe.
