Concrete Material Weights

Knowing the Specific gravity of material is important when trying to accurately pinpoint product weight. In the below chart I have given weights for the various materials that are commonly used in the production of concrete products. I have gathered these weights from various websites and texts, and believe them to be fairly accurate, but remember that material weights can very by their level of compaction. As an example, Cement can weigh any where from 50-100=lbs per cubic foot depending on it’s level of compaction.
