LWAC generally exhibits lower splitting tensile strength than normalweight concrete of equal compressive strength. ACI design codes introduce a modification factor (
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).
ACI 213R-14 is a developed by ACI Committee 213. It is not a code like ACI 318, but rather a comprehensive guide that summarizes the present state of technology for structural lightweight-aggregate concrete. The document interprets data from numerous laboratory studies and real-world applications, providing users with the accumulated knowledge and best practices for working with this specialized material.
A minimum 28-day compressive strength of 17 MPa (2500 psi).
This chapter provides crucial,, actionable information on designing structures with lightweight concrete, referencing structural codes (ACI 318) for shear, bond, and reinforcement requirements. Advantages of Using Lightweight Concrete (ACI 213R) aci 213r-14 pdf
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.

Chapter 4 and 5 of ACI 213R-14 detail how to design mixes. Lightweight mix design deviates from standard volumetric methods (like ACI 211.1) due to aggregate absorption rates. It addresses the unique problem of lightweight aggregate:
Aligns with (Building Code Requirements for Structural Concrete), offering specific modifications needed when using lightweight aggregate to ensure structural integrity. Advantages of Using ACI 213R-14 Guidelines
Engineers and contractors search for the ACI 213R-14 PDF because it serves as the bridge between theoretical design and job-site reality. It isn't just a list of rules; it is a collection of best practices derived from decades of field performance and laboratory testing. Whether you are designing a deck for a long-span bridge or a floor system for a 50-story skyscraper, the data within this guide ensures the structure will behave as predicted under load.

Understanding ACI 213R-14: Guide for Structural Lightweight-Aggregate Concrete
To prevent the aggregates from sucking up mixing water during transit—which causes rapid slump loss—aggregates must be pre-wetted prior to batching. Stockpiles are continuously sprinkled with water to achieve a high thermal and moisture saturation level. Pumping Lightweight Concrete
