This guide presents information on materials, fabrication, properties, design, and handling of precast concrete floor, roof, and wall units having oven-dry unit weights of 50 pcf (800 kg/m3 ) or less. The concrete achieves the low density through the use of gas-releasing agents or the mechanical incorporation of air.
Keywords: cellular concretes; concrete construction; concrete slabs; deflection; floors, lightweight concretes; precast concrete; prefabrication; roofs; structural design; thermal conductivity; walls.
