One of the most common floor systems used in multi-story commercial construction is concrete placed on metal decking. Concrete placed on metal decks is either normal weight concrete, typically weighing from 145 to 155 pounds per cubic foot, or lightweight concrete, typically weighing 110 to115 pounds per cubic foot. The structural design and fire rating of the floor assembly dictates the concrete density, strength, and slab thickness. Commonly, concrete is placed utilizing a truck-mounted pump to convey the concrete up to the elevated slab where the concrete is placed on the corrugated metal decking. The concrete must be proportioned appropriately to meet strength, density, workability, and conveyance requirements.
The specification and construction of a properly designed elevated floor system is possible if a number of factors are considered. The materials and design of the substrate, flooring adhesive, and flooring materials must all be evaluated to check for compatibility with each other and their ability to perform within the desired construction schedule. The timeline must be realistic for the materials involved. If the materials cannot perform in the desired timeframe, other strategies must be incorporated to improve the performance.
