ABSTRACT
Perhaps one of the most important mechanical material property data for refractories is compressive stress-strain data. Unlike the utimate compressive strength data, the compressive stress-strain data provide both the ultimate compressive strength and the matching ultimate compressive strain. The compressive stress-strain data provide valuable information on the mechanical behavior of quality superduty fireclay brick. High-alumina brick is a highly popular form of refractory used throughout industry. High-alumina brick belongs to the alumina-silica group containing an alumina content of 47.5% or higher. There is considerably less compressive stress-strain data available in the literature for basic brick than for high-alumina brick. However, the following basic brick compressive stress-strain data provide valuable information in comparing the stiffness of basic brick with high alumina brick. This type of information is greatly needed by the user to make judgments and decisions on the design of the basic refractory lining system. Several basic brick products are used to illustrate the compressive stress-strain of MgO basic brick.
