Abstract |
AB |
[DE] Bei dem Verfahren zur Herstellung von Verbundsteinen oder -platten, bestehend aus einem tragenden Element aus einer zement- und/oder kalkhaltigen Masse und einer vorgefertigten, dekorativen Deckplatte aus silikatischem Material, wird die zement- und/oder kalkhaltige Masse in plastischem Zustand an die in einer Form angeordnete Deckplatte angegossen oder angepreßt. Die Verbundsteine oder -platten werden nach dem Erreichen der Grünstandsfestigkeit einer Betonmasse bzw. nach dem Anpressen einer Kalksandsteinmasse einer Dampfdruckhärtung in einem Autoklaven bei Temperaturen von 150 bis 230°C unterzogen.
[EN] Prodn. of composite bricks or slabs (I), consisting of a support (II) made from a compsn. (III) contg. cement and/or lime and a ready-made decorative cover plate (IV) or silicate, involves moulding (III) in the plastic state in a mould contg. (IV). The novelty is that when (I) have reached the green stage strength of a cement concrete compsn. or a lime-sandstone compsn. has been pressed, they are hardened with steam under pressure in an autoclave at 150-230 deg. C. Pref. (III) consists of a normal, porous, glass fibre-reinforced or lightweight cement concrete mix or lime-sandstone mix. (IV) consists of natural stone contg. silicate, pref. granite, a ceramic tile or a glass plate. (V) is milk of lime or cement size, pref. applied to a layer of fibre or fabric. |
