Understanding lightweight concrete requires examining multiple perspectives and considerations. ACI 213R-14 Guide for Structural Lightweight-Aggregate Concrete. This guide includes a definition of lightweight-aggregate concrete for structural purposes and discusses, in a condensed fashion, the production methods for and inherent properties of structural lightweight aggregates. Current practices for propor-tioning, mixing, transporting, and placing; properties of hardened concrete; and the design of structural concrete with reference to ACI 318 are all ... lightweight concrete Topic. It's important to note that, 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].
E1-07.fm - American Concrete Institute. CHAPTER 1—INTRODUCTION Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. This perspective suggests that, topicdetail - American Concrete Institute. The American Concrete Institute (ACI) is a leading authority and resource worldwide for the development and distribution of consensus-based standards, technical resources, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete design, construction, and materials, who share a commitment to pursuing the best use of concrete. This perspective suggests that, design Properties of Lightweight Concrete.
Effect of Initial Curing on Carbonation of Lightweight Concrete Masonry .... Initial curing was performed from 4 to 18 hours at Definition of low-density concrete. What is structural low-density concrete?
Mechanical Properties of High-Strength Lightweight Concrete. 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.
