Abstract

Composite concrete blocks are made for the construction of roads, footpaths etc., used by vehicles or pedestrians, starting from a mould with several recesses(a) in its base. Panels or tiles(b) with a thickness larger than the depth of recesses(a) are located in the recesses, and the gaps between the tiles(b) are filled with sand or a similar material. Tiles(b) are made of natural and/or synthetic materials, or ceramics; and one or more layers of concrete(c) are poured into the mould, which is vibrated. After setting, the block is stripped from the mould and the sand replaced by mortar which forms joints between tiles(b). The mould is then used as a protective cover for the block. The concrete pref. contains a reinforcing grid, esp. a grid made of metal strips standing on edge. Pref. the mould is of polystyrene and the concrete contains 5-20% pasticised vinyl polymer resin. Any desired material can be used for the tiles(b) which form the working surface of the blocks.

Description

Verfahren zum Herstellen von begeh- oder befahrbarenProcess for producing walkable or drivable

Platten, Trittstufen od.dgl.Plates, steps or the like.

Die Erfindung betrifft ein Verfahren zum Herstellen von begeh- oder befahrbaren Platten, Trittstufen od.dgl. unter Verwendung von ebenen Körpern aus Kunst- oder Naturstein bzw. keramischen Materialien, die in formgleichen Ausnehmungen in Formkästen eingelegt und rückseitig mit Betonmörtel abgedeckt sind, nach Patent................The invention relates to a method for producing walk-in or drivable plates, steps or the like. using flat bodies Artificial or natural stone or ceramic materials in recesses of the same shape are placed in molding boxes and covered on the back with concrete mortar, according to patent ................

(Patentanmeldung P 27 51 706.2).(Patent application P 27 51 706.2).

Die Erfindung hat eine Fortbildung des Verfahrens nach dem Hauptpatent zur Aufgabe.The invention has a development of the method according to the main patent to the task.

Wolfgang Schubert, 8602 Memmelsdorf Peter Reuss, 8602 Memmelsdorf Erfindungsgemäß + f es dadurch erreicht, daß dem Betonmörtel eo we- e~hgemachees Kunstharz im Verhältnis von 5 bis 20% des Zementanteiffls beigemischt wird. Bevorzugt kann als Kunstharz Vinyl-Terpolymerisat dienen. Durch den Harzzusatz , der als Dispersion zum Einsatz gebracht wird, sind unter Einsparung einer Teilmenge des Anmachwassers die Festigkeitswerte, insbesondere die Biege- Zugfestigkeit des Betonmörtels verbessert, was die Schichtdicke desselben zu verkleinern erlaubt und bei weniger belastbaren Platten, z.B. begehbaren Bodenplatten unter Verzicht auf einen mehrschichtigen Aufbau die Anwendung von Bewehrungen im Betonmörtel unnötig macht.Wolfgang Schubert, 8602 Memmelsdorf Peter Reuss, 8602 Memmelsdorf According to the invention + f it is achieved by the fact that the concrete mortar is made up of synthetic resin in proportion from 5 to 20% of the cement content is added. Can be preferred as synthetic resin Vinyl terpolymer are used. Through the addition of resin, which is used as a dispersion is brought, while saving a portion of the mixing water, the strength values are in particular, the flexural tensile strength of the concrete mortar improves, which improves the layer thickness The same can be reduced in size and with less resilient panels, e.g. walkable Floor slabs without a multilayer structure the use of reinforcement makes unnecessary in concrete mortar.

Außerdem wird durch den Kunstharz zusatz eine Sperrwirkung auf den Kapillareffekt der Mörtelmasse ausgeübt und damit die Frostempfindlichkeit des Betonmörtels gesenkt. Schließlich ist auch die Dichtigkeit erhöht und das Fließvermögen verbessert.In addition, a blocking effect on the synthetic resin is added Capillary effect exerted by the mortar mass and thus the frost sensitivity of the concrete mortar lowered. Finally, the tightness is also increased and the flowability improved.

Eine vorteilhafte Verarbeitung des Kunstharzzusatzes ist erreichbar, wenn die Dispersion desselben mit dem Mörtelanmachwasser vermischt den Mörteltrockenmassen im Mischer beigegeben wird.An advantageous processing of the synthetic resin additive can be achieved, when the dispersion of the same with the mortar making water mixed the mortar dry matter is added in the mixer.

Einer Steigerung des Luftporengehalts durch den Mischvorgang, insbesondere bei Verwendung von kleinem Anteil Kunstharzdispersion wird gemäß weiteren Verfahrensschritten durch die Zugabe eines Entschäumers entgegengewirkt. Ein geeigneter Entschäumer kann z.B. Silicon -Antischaumemulsion sein. An increase in the air void content as a result of the mixing process, in particular if a small proportion of synthetic resin dispersion is used, further process steps are used counteracted by adding a defoamer. A suitable defoamer can e.g. be silicone antifoam emulsion.
