Designing Concrete Mixes for Increased Fire or Heat Resistance
Aug 01 1974 · One factor that is seldom considered in striving for a high degree of fire or heat resistance in a concrete structure is the design of the concrete mixture itself. And yet to name just one example a study has shown that an appropriate change in the type of aggregate used can sometimes double the fire endurance of concrete.

Evaluating Refractory PropertiesResco Products
Refractory Properties. Refractory properties are broken into mechanical physical properties and high-temperature properties. Typically refractory materials are characterized by density strength and response to heat treatment. Certain physical properties are also measured and recorded during manufacture and serve as a basis for quality control.

Combined heat insulation from lightweight refractory and
The use of double-layer linings consisting of lightweight or cellular concrete and lightweight refractory has been established in principle. Keramzite concrete with a water-glass bond containing nepheline slurry possessing the best adhesive properties in the cold and hot states are recommended as the lightweight concrete. Heat-resistant gassed concrete is recommended as the cellular concrete.
