  • Producing structural lightweight concrete block

    The Expanded Shale, Clay Slate Institute defines lightweight masonry as being less than 94 pounds per cubic foot (or a 25pound, 8x8x16inch CMU). Many blocks are called "lightweight" when, in reality, they are semilightweight or mediumweight block. Commercially available lightweight concrete block range from 85 pounds per cubic foot (a 22pound, 8x8x16inch CMU) to 105 pounds per cubic ...
