One persistent myth is that lightweight concrete is less durable. ACI 213R-14 disproves this with data. It shows that properly air-entrained LWC has exceptional freeze-thaw resistance. Furthermore, due to its lower conductivity, LWC provides significantly better fire resistance than normal weight concrete of the same thickness.

The guide provides data on the mechanical behavior of structural lightweight concrete: aci 213r-14 pdf

ACI 213R-14 provides comprehensive guidance on the use, design, production, testing, and quality control of structural lightweight-aggregate concrete (LWAC). This paper summarizes the document’s scope, key provisions, material characteristics, mix design considerations, testing/quality-control procedures, structural design implications, durability/performance aspects, typical applications, and recommendations for practice. It also highlights updates in ACI 213R-14 relative to earlier editions and notes resources for obtaining the full PDF. One persistent myth is that lightweight concrete is

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). Furthermore, due to its lower conductivity, LWC provides
