Aci 213r-14 Pdf ((top))

This guide serves as a primary resource for engineers and contractors working with lightweight-aggregate concrete (LWAC). It focuses on materials with a density significantly lower than normalweight concrete—typically ranging from 90 to 115 lb/ft³ (1440 to 1840 kg/m³)—without sacrificing structural integrity. Key Content and Technical Focus

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. aci 213r-14 pdf

This is the most dog-eared section in any physical copy. It walks the engineer through the Trial Batch method. It addresses the unique problem of lightweight aggregate: Absorption . Because LWA is porous, it absorbs mixing water. The ACI 213R-14 guide explains the concept of "absorption and surface moisture" and warns against using too much water, which leads to segregation (the lightweight particles floating to the top). The "R" stands for "Report" or "Guide," distinguishing
