It was the object of the present study to investigate and characterize the microstructure and the phase assemblage of high alumina refractory concretes as a function of temperature. The investigations were done using XRD and SEM methods including X-Ray microanalyses.
Refactory concretes are defined and a brief discussion of the calcium aluminate cements which form their hydraulic bond is followed by a description of the early work which probably led to the first recorded use of a refactory concrete. A short historical account is given of the development (and some interesting uses) of refractory castable mixes before and after World War II. Attention is drawn to some of the basic differences in properties between refactory brickwork and refractory concrete, and to the value of refractory concrete for experimental or pilot-scale development work.

A wide variety of aggregates, both dense and lightweight is used in refractory concretes. There are also several types of cement. Thus a wide variety of refractory concrete products with markedly different properties is available. Installation, curing, drying and heating practices also affect the properties of refractory concretes markedly.
A review of operational experience of typical refractory concrete installations with empahsis on failures, their causes and the lessons learned. Self-supporting, suspended, precast, and lining type applications are included.

High temperature thermal insulation materials that are lightweight, durable, and low cost have important applpications in heat recovery steam generators (HRSG) designed for high efficiency modern power plants that produce power at combined efficiency (PACE). . .State-of-the-art samples tested in the duct manways of the Public Service Company in Lawton, Oklahoma survived conditions of blast, heat, and transient temperatures.
