摘要： The invention concerns a component in the form of an autoclave-hardened high density moulded body with a structure of grained steelworks slag, in particular of lime silicate steelworks slag such as Linz-Donawitz and/or electric furnace clinker, with a graduated grain size composition or distribution with a high packing density, preferably in the range of between 0 and 6 mm, in particular between 0 and 4 mm. The slag grains are firmly cemented to one another via silicate hydrates formed in a hydrothermal process. The invention further concerns a method of producing high-density components.

摘要： On prepare un melange apte a etre coule, consistant essentiellement en un materiel granuleux, notamment des silicates, de l'eau, du ciment et de la mousse, on le met dans un moule, apres quoi on demoule l'ebauche lorsqu'elle presente une resistance suffisante et on la durcit. Pour pouvoir fabriquer simplement et rapidement des briques de densite constante, on ajoutera au melange, avant de remplir le moule, un additif eleveur de temperature et accelerateur de prise qui, dans le moule, echauffera le melange final au moyen de champ electrique a haute frequence a une temperature homogene comprise entre 40 et 80 C. L'echauffement dans le moule du melange final se fait si rapidement que le mouvement d'expansion du melange du a l'echauffement est termine avant la prise du ciment. L'element est demoule apres un echauffement de 20 a 120 s.

摘要： In a method for manufacturing foam concrete elements, a mixture appropriate for casting is prepared, comprising substantially a granular material, particularly silicates, water, ciment and foam, the material being poured in a mold, and thereafter the blank is withdrawn from the mold when it has acquired a sufficient resistance and it is finally allowed to harden. In order to readily and rapidly manufacture constant density bricks, before filling the mold, a temperature riser and setting accelerator agent is added to the mixture, this agent heating the final mixture in the mold by an electric field at a high frequency and a homogenous temperature comprised between 40 and 80 C. The heating in the mold of the final mixture is effected so rapidly that the expansion of the mixture due to the heating is finished before the setting of the ciment. The element is withdrawn from the mold after a heating comprised between 20 to 120s.
