### Crushing Strength of Reinforced Concrete Membranes

Date: 9/1/1988. Abstract: Develops a methodology for the determination of the crushing strength of reinforced concrete membranes with two-way orthogonal reinforcement on the basis of theoretical considerations and experimental results. It differs from previous work in this area with respect to two principal features.

More### Strength of Concrete (PSI) ProMatcher

Concrete with a PSI rating of 6000 or more is considered high-strength concrete. It is typically found in nuclear power plants and other areas where radiation contamination is possible. High strength concrete has a lower water-cement ratio, giving it additional durability and strength. Free Quotes from Concrete Contractors.
