) factor used to reduce shear and development length capacities when using lightweight materials. 4. Jobsite Practices
Proportioning SLC is more complex than standard concrete. ACI 213R-14 details the "volumetric method" for mix design. Because lightweight aggregates absorb water, the guide explains how to calculate "free water" versus "absorbed water" to ensure consistent workability. 3. Structural Design Considerations aci 213r-14 pdf
The American Concrete Institute (ACI) publishes ACI 213R-14, titled "Guide for Structural Lightweight-Aggregate Concrete." This document is the primary industry standard for engineers and contractors working with lightweight materials. It provides comprehensive technical data on the properties, proportioning, and application of structural lightweight concrete (SLC). ) factor used to reduce shear and development
