    摘要: A method of controlling the ratio of hydration time (HT) to open time (OT) in the manufacture of composite materials from a mixture containing hydratable calcium sulphate such as gypsum binders, aggregates, fibers, water additives and other additives is disclosed. The method includes adding a retarder-accelerator combination such as Retardan and potassium sulphate to the mixture and applying pressure. The retarder-accelerator combination and application of pressure provide advantageous reduction in the ratio HT:OT. More particularly, HT:OT can be reduced to less than 1.

    摘要: Durable molded construction parts are disclosed, which are prepared from hydration products of a settable construction material comprising a hydraulically hardening mixture and at least one reinforcing material subject to degradation under alkaline conditions. The construction material has an alkali buffer capacity which does not exceed 0.005 acid equivalents per 100 grams of construction material, as measured in an aqueous suspension of the construction material 24 hours after suspension formation.

    摘要: The invention provides an installation and method for the continuous production of materials using exothermically hardening binders, such as gypsum or cement, comprising a mixing and feeding station and a calibrating unit or press and also a control system for operating the installation. This installation is distinguished by the fact that the distance between the feeding station and the entrance to the calibrating unit or press on the one hand and the distance between the feeding station and the end of the calibrating unit or press on the other hand, taking into account the duration of the mixing and forming time, corresponds to the ratio between the period of time from the beginning of mixing to the beginning of stiffening and the period of time from the beginning of mixing to the end of hydration, and by the fact that the rate of advance of the continuous installation is controlled in such a way that the exothermically hardening binder reaches its maximum temperature shortly before leaving the calibrating unit or press.

    摘要: The invention relates to a method for continuous manufacture of materials,specially material slabs, from mixtures of binders, reinforcing agents, and possibly additives, the mixtures being cured by hydrate formation and being of a pourable or spreadable consistency. The special properties and usability of the materials are achieved by a permanent and irreversible compression of the initially-formed structure, whereby an extruded slab is formed from the mixture, then compressed and calibrated. The extruded slab is first compressed in a compression phase at a pressure which is sufficiently high that the slab's thickness after compression is less than the specified value of the finished extruded slab, and its density specified final density, the resulting values of density and degree of compression being sufficiently high that the compressed extruded slab is calibratable immediately thereafter in a calibration phase without the active application of pressure. In addition, the invention provides a device for working this method.
