Definition of Concrete MPa | HunkerDiese Seite übersetzen

Known for its strength and durability, concrete is used to construct buildings, bridges and roadways. To ensure a concrete structure will last, inspectors test the strength of the concrete once it has had time to dry. In countries that use the metric system, the strength of concrete is rated using megapascals (MPa).
