Guide for Precast Cellular Concrete Floor, Roof, and Wall Units
1996, 5 pp.
$38.50

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/m 3 ) or less. The concrete achieves the low density through the use of gas-releasing agents or the mechanical incorporation of air.-
