Heat effects on reinforced concrete

Heat effects on reinforced concrete

Heat effects on reinforced concrete

The steel making process requires reinforced concrete walls and floors of structures to be in close proximity and exposure to extreme high temperatures. Based upon observations at numerous facilities, these temperatures combined with a wet environment cause spalls, exposing the reinforcing steel. Corrosion soon follows, but is generally not extreme. Maintenance of damaged deteriorated spalled areas can only be made during planned shutdowns.

The spray chamber near the caster is an example of a structure that often experiences problems that I suspect are primarily due to extreme prolonged heat exposure. The structure is generally a tower say 20 feet square and say 60 feet tall. Thermal expansion is not likely the source of problem.

What can be done to protect the concrete wall surfaces exposed to these severe conditions? I've considered increased depth of reinforcing steel in the walls. Is a coating on the face of the wall a possible solution? Perhaps an expendable heat shield would help?

RE: Heat effects on reinforced concrete

Are you using concrete that is formulated for high temp use?
Perhaps facing it with refractory brick would work.
We used special concrete on foundry floors and in some areas used brick inlay.

RE: Heat effects on reinforced concrete

Did you add heat-resistant concrete facing or construct the structure of a special heat-resistant material?

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
eBook - Efficient and Effective Production Support with 3D Printed Jigs and Fixtures
Jigs and fixtures offer manufacturers a reliable process for delivering accurate, high-quality outcomes, whether for a specific part or feature, or for consistency across multiples of parts. Although the methodologies and materials for producing jigs and fixtures have evolved beyond the conventional metal tooling of years past, their position as a manufacturing staple remains constant due to the benefits they offer.
