Title: Guide for Cast-in-Place Low-Density Concete
Author(s): ACI Committee 523
Publication: Journal Proceedings
Appears on pages(s): 830-837
Keywords: accelerating agents; admixtures; aggregates; air entrainment; cellular
concretes; compressive strength; concrete construction; fire resistance;
foaming agents; formwork (construction); insulating concretes; lightweight aggregate.
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.
