Guide for Cast-in-Place Low Density Cellular Concrete
2006, 13pp.
$47.50

This guide provides information on the materials, properties, design, proper handling, and applications of cast-in-place low-density cellular concretes having oven-dry densities of 50 lb/ft3 (800 kg/m3) or less. Roof deck systems and geotechnical applications often incorporate these low density cellular concretes.

Keywords: cellular concrete; engineered fill; foaming agent; geotechnical fill; insulating concrete; insulating concrete roof decks; low-density cellular concrete; low-density controlled low-strength material (LD-CLSM); preformed foam.
