本指南提供了烘箱干密度小于等于50 lb/ft3（800 kg/m3）的现浇低密度多孔混凝土的材料、性能、设计、正确处理和应用方面的信息。屋顶板系统和岩土工程应用通常包含这些低密度多孔混凝土。

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.
