Abstract:
Cellular ceramic materials, for example closed cell glass ceramic materials, for use in construction of buildings comprising a clay material, carbon, and water used to form the cellular ceramic blocks, slabs and beams by expansion of the particles inside the ware. The cellular ceramic materials are produced by first mixing the clay, carbon and about 40% to about 70% water by weight of the clay in the mixture, allowing the mixture to cure, drying the cured mixture, then firing the dried mixture at a temperature and for a period of time sufficient to melt the surface of the mixture. The clay material can be, for example, surface clays, ball clays, kaolin, shale, fly ash and/or bentonite. In another embodiment a mixture of volcanic ash, carbon and water can be formed and layered with the mixture of clay, carbon and water. The cellular ceramic materials are, in most cases, impervious to liquid, are capable of supporting substantial loads in tension and compression without reinforcement, and require no additional insulating material. Such cellular ceramic material may also be used in the construction of buildings with a metal skeleton comprising metal bars forming a structure for supporting the cellular ceramic building material.
Abstract:
Die Erfindung betrifft einen feuerfesten, keramisch gebrannten, kohlenstoffgebundenen Magnesiastein, dessen Matrix über 70 Gew.-%, insbesondere von 80 bis 98 Gew.-% MgO-Körner sowie eine aus einer Verkokung resultierende Koksgerüst-Bindematrix und Poren aufweist, wobei a) die MgO-Körner über eine Kohlenstoffbindung des Koksgerüsts fixiert sind und b) mindestens 30 %, insbesondere 50 bis 100 % der MgO-Körner jeweils mindestens eine aus dem keramischen Brand resultierende Sinterbrücke aufweist.
Abstract:
Disclosed are a fire-resistant ordinary ceramic batch and a fire-resistant product predominantly comprising a) at least one granular, fire-resistant, mineral, alkaline main component made of an MgO-based or MgO and CaO-based fire-resistant material that is based on at least one alkaline fire-resistant raw material, and b) at least one granular, fire-resistant, mineral, MgO-based, additional elasticator in the form of a forsterite material or a mixture forming forsterite material preferably as small molded articles, such as pellets or granulate that is comminuted from compacts. The small molded articles have a grain size ranging from 0.3 to 8 mm while being advantageously provided with a binder at an amount that elasticates the main component.
