Abstract:
Refractory concretes are currently used in a wide variety of industrial applications where pyroprocess-ing and/or thermal containment is required. The service demands of these applications are becoming increasingly severe and this, combined with the constant demand for refractories with enhanced service life and more efficient means of installation, has resulted in an ever expanding refractory concrete technology. ACI Committee 547 has prepared this state-of-the-art 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 state-of-the-art construction details and repair/maintenance techniques. Also included is an in-depth review of a wide variety of applications together with the committee’s assessment of future needs and developments. [Authors]
