Structural lightweight aggregate concrete (LWAC) is a critical material in modern construction. It allows engineers to reduce structural dead loads without sacrificing mechanical performance. The American Concrete Institute (ACI) provides the definitive framework for this material in its document .
Reducing structural self-weight allows engineers to specify smaller columns, thinner slabs, and less foundation piling. This is exceptionally cost-effective for high-rise buildings and long-span bridges. 2. Internal Curing (IC) aci 213r-14 pdf

Best practices for specifying, proportioning (mix design), mixing, and handling to ensure the concrete performs reliably. proportioning (mix design)
is the industry-standard document published by the American Concrete Institute (ACI) that provides comprehensive guidelines for designing, proportioning, and using lightweight concrete. Core Definition & Scope
ACI 213R-14 does not exist in a vacuum. It is part of a larger ecosystem of standards that provide a complete framework for concrete construction. These include:
: Longer beams and slabs can be achieved in high-rise buildings and bridges.
