Abstract:
This guide presents information on materials, fasbrication, properties, design and handling of cellular concretes with oven-dry densities greater than 50 pcf (800 kg/m^3) but whose compressive strengths are less than 2500 psi (175 kgf/cm^2). The usual density range of the concrete considered is less than 50 pcf to 120 pcf. Those concretes in the lower portion of this range are generally used for thermal and sound insulation fills for roofs, walls and floors. At the higher densitites they are used in cast-in-place walls, floors, and roofs, and also for precast elements such as wall and floor panels.
