Thermal Conductivity of Refractory Insulating Concrete

Journal of the American Ceramic Society, 1953
The thermal conductivities and unit weights of seventeen refractory insulating Lumnite cement concretes were determined over the approximate temperature range 500° to 2000°F. The thermal conductivities of all the concretes increased with an increase in temperature, which is usual for amorphous bodies.

Vibroformed dinas-quartzite refractory concrete parts

Refractories, 1989
The possibility of production of vibroformed dinas-quartzite parts with properties practically no different from those rammed with manual pneumatic rammers and meeting TU 14-8-129-74 has been shown.

Biaxial Compression Testing of Refractory Concretes

1983
In the past, the design of large refractory lined process vessels, such as used in coal gasification, has been based on operating experience. During the 1970’s, efforts were funded by the Department of Energy (DOE) to develop mathematical models that would predict the thermo-mechanical behavior of refractory concrete lined coal gasification process ...

High-alumina cement for refractory concretes

Refractories, 1986
Etude de l'influence du durcissement avec traitement hydrothermal sur la resistance de beton refractaire a base de ciment alumineux. Relation entre la resistance et la composition des produits d'hydratation et aussi entre les variations de resistance et les transformations thermiques des produits d'hydratation au cours du chauffage de la pierre de ...

Heat-resisting and refractory concretes

2003
The definition of refractory concrete will vary depending on the specific reference. However, a good general definition is: “Concrete which is suitable for use at high temperatures composed of hydraulic cement (calcium aluminate cement) as the binding agent, combined with heat resistance, refractory aggregates and or fillers.” The boundary between heat-

Refractory concretes for steel-teeming ladles

Refractories, 1989
Etude comparative de 3 types de betons refractaires a base de melange quartz-argile (plus l'un ou plusieurs de ces composes: quartzite, lignosulfonate, verre soluble, scorie ferrochrome, briques chrome-magnesite broyees) utilises comme garnissage monolitique de poches de coulee pour acier.

Properties of cast magnesial refractory concretes

Refractories, 1979
The rheological and physical properties of cast magnesial concretes and the relationship between these properties have been studied. It is established that with an increase in the compressive load, the shear deformation of the cast concretes decreases sharply and the concretes become more rigid.

Furnaces with a refractory-concrete lining

Chemical and Petroleum Engineering, 2006
Advantages of concrete over brick linings are indicated. The following furnace descriptions are given: high-temperature furnaces fired by natural gas or fuel oil, furnaces in Claus plants, and furnaces with after-burning of acid gases and an abrasive effect on the lining.

Pneumatically Placed Concrete and Refractory Materials

IEEE Transactions on Aerospace, 1963
The pneumatic placement process and its advantages of speed, flexibility and economy are reviewed. Various applications of the process to aerospace support are discussed. Details are given in regard to 1) "hard" refractories applied to launch pads and heat shields, 2) insulating refractory coatings which serve as protection for structural steel and ...
