Inspection Manual for Precast Concrete Pipe and Structures

Compressive Strength. Compressive strength of pipe is a very critical property of the concrete pipe and is determined by testing pieces of pipe in a three-edge-bearing machine (Figure 1-1) in accordance with AASHTO T 280or by breaking concrete cylinders in accordance with AASHTO T 22. Compressive

CIVL 1101 - Part 14 - Testing of Hardened Concrete

The most important results form this test are the compressive and shear strengths. Accelerated Tests. When the standard compression test was first introduced, construction practices and cement quality were not what they are today. We also realize that the strength of a standard cylinder test is a true representation of the concrete strength.
