• Abstract:

  Concrete made with lightweight aggregates–called lightweight concrete–offers a lighter dead load and better insulating properties than concrete of normal weight. While normal-weight concretes have unit weights of 140 to 150 pcf (pounds per cubic foot), lightweight concretes’ unit weights can range from 120 to as low as 20 pcf. These concretes, which offer a full spectrum of compressive strengths, thermal resistances, fire resistances, and costs, can be used to construct high- and low-rise buildings, bridges, religious facilities, sports arenas, floor slabs, roof decks, and fire barriers.
