| Abstract: | Magnesia and silica brick should be protected from the action of the weather. Open textured fireclay brick (usually having end cold crushing strengths of less than 1500 pounds per square inch) should be afforded protection from the action of the weather. Finely ground, dense, hard-burned firebrick , especially those of medium or low refractoriness. may be exposed to the action of weather with a reasonable amount of safety. These are usually made from one clay which is shaped on a dry press or auger machine and have an end cold crushing strength approximating 5000 pounds per square inch. |
