The use of expanded shale and clay (ES&C) aggregates, which are also known as low-density aggregates are consistently used worldwide in a wide range of applications. Structural lightweight concretes are most commonly produced with expanded shales, clays, slates, slag, pumice, or scoria, which occur naturally from volcanic rocks. Lightweight concrete is used for a number of reasons, including excellent sound reduction, fire resistance, insulation, seismic performance, lighter weight, and geotechnical properties. Moderate strength concrete can be considered the middle ground between low density, and structural lightweight concrete.
