Structural lightweight concrete is defined by its use of lightweight aggregates, such as expanded shale, clay, or slate, which result in a significantly lower density than normalweight concrete. While standard concrete typically weighs between 140 and 150 pounds per cubic foot (pcf), SLWC generally ranges from 90 to 115 pcf. Despite this reduced weight, the material maintains a compressive strength comparable to traditional concrete, typically exceeding 2,500 psi.
The primary benefit of following the ACI 213R-14 guidelines is the significant reduction in on a structure, which can lead to smaller foundation sizes and reduced reinforcement requirements. Key performance areas discussed in the guide include: aci 213r-14 pdf
