The standard defines lightweight aggregate concrete for structural purposes, providing guidelines for design and construction that allow structures to be built with the same confidence and reliability as normal-weight concrete. Key Takeaways of the 213R-14 Standard:
ACI members often have access to the digital library, including this guide. normal-weight concrete | | Shrinkage & Creep |
Standard Test Method for Determining Density of Structural Lightweight Concrete.
Long-term deformation characteristics are discussed, highlighting how the internal moisture reservoir of porous aggregates can actually mitigate autogenous shrinkage through "internal curing." 4. Construction Practices: Batching, Mixing, and Placing
Defines structural lightweight concrete, typically having an air-dry density of less than 115 lb/ ft3f t cubed Performance: Reviews in-service performance.
