Abstract:
This guide provides information on materials, properties, design, and proper handling of cast-in-place concretes having oven-dry unit weights of 50 pcf (800 kg/m’) or less. These concretes achieve their low unit weight by incorporating low-density aggregates, air entrainment, or preformed foam. These concretes are most commonly used in roof deck systems, where their advantages include insulating value, the ability to be sloped-to-drain, and improved fire resistance.
