The weight of the concrete topping is conservatively based upon the nominal thickness. So in the example given above, we would design assuming a uniform concrete topping thickness of 1¼" and a weight of 25 psf. In doing so, we are not stating or even implying as to the integrity of 1¼" of concrete topping, as this must be evaluated by the ...

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined.

Question: What's the nominal weight of standard concrete? Answer: Anyone who has ever moved it by the shovelful will tell you fresh concrete is heavy, but just how heavy it is depends on the mix proportions and the particular ingredients. A good rule of thumb for most concrete mixtures is 150 pounds per cubic foot. If you fill a 5-gallon bucket you've moved nearly 100 pounds of concrete.

The concrete weight can vary depending on the air and moisture content it contains. Cement density (weight) can be 830 - 1650 kg per cubic meter or 52 - 103 lbs per cubic foot. Cement that is pneumatically loaded into silos is less dense while cement that has been stored and exposed to vibration, like being transported, is more dense.
