The design properties of lightweight concrete are discussed in ACI 213R “Guide for Structural Lightweight-Aggregate Concrete”. Chapter 5 covers physical and mechanical properties while Chapter 7 discusses the design considerations. References: ACI 213R-14. Topics in Concrete: Design; Lightweight

Sep 1, 2024 · Lightweight concrete (LWC) finds wide-ranging applications inthe construction industry due to its reduced dead load, good fireresistance, and low thermal and acoustic conductivity. Lightweightgeopolymer concrete (LWGC) is an emerging type ofconcrete that is garnering attention in the construction industryfor its sustainable and eco-friendly ...

In comparing the fatigue properties of ordinary concrete of 2250 kg/m3 (3792 Ib/yd3) density and those of lightweight concrete of densities ranging from 1500 to 1800 kg/m3 (2528 to 3034 Ib/yd3), it is evident that both types of concrete have the same susceptibility to fatigue and that, for compressive stresses, the fatigue strength can be ...

May 1, 1991 · The ultimate strain at peak load for the concrete varied from 3.3 to 4.6 mm/m, which is higher than that of normal weight concrete. For the high-strength lightweight concrete, the shape of the ascending part of the stress-strain curve was more linear than that of lightweight concrete with low to medium strength.

Apr 9, 2025 · ACI Concrete Terminology. Structural low-density (lightweight) concrete is structural concrete made with low-density aggregate having an air-dried density of not more than 115 lb/ft3 (1850 kg/m3) and a 28 day compressive strength of more than 2,500 1b/ ft2 (17 MPa) [ACI 213R].
