Crushing strength of concrete rings with a polyurea ...
2020-7-1 On this basis, the relation between the coating application method and the crushing strength and failure mechanism was examined and analyzed. The results show that applying the polyurea coating on both surfaces of concrete rings improves their crushing strength by 20.3% and makes it possible to use an object safely following the concrete cracking.

Standard Deviation for Compressive Strength of
2020-7-19 Standard deviation for concrete is the method to determine the reliability between the compressive strength results of a concrete batch. The standard deviation serves as the basis for control of variability in the test results of concrete for the same batch of concrete. It is a statistical method that is based on the correlation analysis, 
Properties of Concrete Blocks — Strength
It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year. A block 12 inches wide and 24 inches long has a total surface of 288 square inches, or, deducting ⅓ for openings, a net area of 192 inches.
