The primary purpose of the document is to explain how lightweight concrete behaves differently from normalweight concrete (NWC). It translates these physical differences into practical guidelines for structural design, mix proportioning, and field handling.
The guide explains the modification factor ( aci 213r-14 pdf
Techniques to optimize the mix, often requiring higher cement content than normal-weight concrete. The primary purpose of the document is to
This guide serves as a bridge between lab research and field application, offering data-driven insights into how lightweight aggregates (LWA) behave under structural loads. aci 213r-14 pdf
You need both, but ACI 213R-14 provides the structural design context that ASTM lacks.
