What density is typically associated with Lightweight (LWT) concrete?

Lightweight (LWT) concrete is typically characterized by a lower density than standard concrete, which enhances its insulating properties and reduces the overall weight of structures. The density that is generally associated with LWT concrete is around 110 pounds per cubic foot (pcf). This lower density is achieved by incorporating lightweight aggregates such as expanded clay, shale, or pumice, which help in achieving these performance characteristics.

This specific density range allows Lightweight concrete to be used effectively in applications requiring reduced weight, thermal insulation, and improved workability. The choice of 110 pcf accurately reflects the common specifications found in industry standards for Lightweight concrete.
