Description

Refractory concretes are currently used in a wide variety of industrial applications where pyroprocessing and/or thermal containment is required. ACI Committee 547 has prepared this report to meet the need for a better understanding of this relatively new technology. The report presents background information and perspective on the history and current status of the technology. Composition and proportioning methods are discussed together with a detailed review of the constituent ingredients. Emphasis is placed on proper procedures for the installation, curing, drying, and firing. The physical and engineering properties of both normal weight and lightweight refractory concretes are reported, as are construction details and repair/ maintenance techniques.
