The cellular structure of expanded aggregates lowers the thermal conductivity (
This factor directly modifies equations governing shear strength, torsion, and reinforcing bar development lengths. Deflection and Creep
The guide spans 53 pages, organized into eight chapters that address key topics:
Fly ash or slag processed on a sintering grate. aci 213r-14 pdf
If you are currently implementing this standard on a project, tell me:
ACI 213R-14 is a comprehensive guide developed by ACI Committee 213. It outlines the specific properties, production methods, and structural design considerations of concrete made with lightweight aggregates. Key Definitions
FRP reinforcement is suitable for a wide range of concrete applications, including: The cellular structure of expanded aggregates lowers the
Most structural lightweight aggregates are manufactured using a rotary kiln or a sintering machine. Materials include:
, serves as the primary technical standard for designing, proportioning, and applying structural lightweight concrete (SLC) to reduce dead loads while maintaining structural integrity. The guide outlines essential practices for managing aggregate absorption, implementing internal curing, and adjusting design calculations for reduced modulus of elasticity and shear capacity.

The is a 48-page guide published by the American Concrete Institute. The "R" stands for "Report" or "Guide," distinguishing it from a mandatory code (like ACI 318). However, in practice, 213R-14 is the definitive reference for specifying, mixing, placing, and curing structural lightweight concrete. It outlines the specific properties, production methods, and
: Building Code Requirements for Structural Concrete (which references 213R for specific lightweight factors). specific application
Typically ranges from 90 to 115 lb/ft³ (1440 to 1840 kg/m³). In comparison, normalweight concrete weighs roughly 145 to 150 lb/ft³.
A byproduct of iron manufacturing that is specially processed. Natural Aggregates
Using structural lightweight concrete successfully requires strict field protocols to avoid segregation and pumping issues. Moisture Conditioning
