Class C Concrete Psi

concrete floor specifications - warehouses & industrial,many of these requirements are defined by the class of floor the owner wants—note that decorative concrete is typically a class 1 floor. floors are classified based on the intended use of the floor—see the table below that was adapted from aci 302.1 r-04, concrete floor and slab construction..actual concrete mix ratios for 3000, 3500, 4000, and 4500,the concrete ticket below shows a 3500 psi concrete mix for 10.5 yards of concrete. the ticket breaks down the weights of the amount of cement, stone, and sand used to make the 3500 psi concrete. the actual weights used to make this 10.5 yard load were: 1. cement = 5,805 pounds. 2..
