Definitions
- the invention relates to a building material made from a powdery or granular base substance which sets in the presence of water by crystallization, recrystallization and / or chemical reaction and is particularly suitable for improving the strength and water resistance of objects which have been manufactured using the building material.
- Powdered minerals are often used as building materials, which are mixed to a paste-like mass by mixing with water and harden after processing by crystallization, recrystallization and / or chemical reaction to form a solid body. Structures formed from this often have a high water absorption capacity, which is undesirable in certain circumstances.
- molded articles, plates, etc. made of plaster are limited in their use and can generally only be used in closed, dry rooms.
- DE 3626048 AI proposes for boards and moldings made of gypsum or gypsum hemihydrate to add liquid polyisocyanates to the water-solid mixture for the production of gypsum boards. If necessary, reinforcement materials in the form of cellulose particles can also be added to the shaped bodies. In another embodiment of the invention mentioned, it is proposed to apply the polyisocyanates to the surface of finished gypsum boards.
- the structure created in this way from the three-dimensional network of the water-free binder and the crystal structures embedded therein has both high strength and good water resistance.
- the disadvantage of this method is that after the shaping step, the water-free binder must first solidify before the mineral building material is cured by the addition of water and the final strength is achieved.
- the object of the invention is therefore to propose a building material which is to be processed like a normal mineral building material, but in the fully cured state in particular brings about a comparatively increased moisture resistance of components.
- such a building material is made from a powdery or granular base substance that sets in the presence of water by crystallization, recrystallization and / or chemical reaction proposed by designing it according to the features of the main claim.
- the basic substance of such a building material consists in particular of the mineral materials described in claim 2 and the coating substances characterized in claims 3 and 4. Particularly advantageous embodiments of the composition of the building material are presented in claims 5 to 8.
- a method for producing a building material according to the invention is presented in claims 9 and following.
- a building material according to the invention consists of a powdery or granular base substance which sets in the presence of water by crystallization, recrystallization and / or chemical reaction and a coating substance.
- Processed natural raw materials such as gypsum, anhydrite or lime or industrially produced building materials such as cement or reactive fly ash or synthetic mineral materials or mixtures of the aforementioned materials are preferably used as the basic substance.
- the individual particles of this basic substance are partially or completely coated with an enveloping substance, which does not cause the basic substance to bind water when it is coated.
- the coating substance used in organic solvents is soluble and / or meltable substances, such as natural or synthetic resins or resin mixtures or organic, inorganic, mineral or synthetic adhesives, adhesive systems or mixtures of the aforementioned substances.
- water-soluble and / or water-insoluble and / or water-swellable substances are used as fillers.
- the invention proposes that the particles of the water-soluble and / or water-insoluble and / or water-swellable fillers can also be completely or partially coated with a water-insoluble substance.
- a building material according to the invention can be produced by mixing a powdery or granular base substance which sets in the presence of water by crystallization, recrystallization and / or chemical reaction with an enveloping substance liquefied by melting or dissolving in an anhydrous solvent.
- the coating substance is solidified by removing the solvent or cooling. It is in the sense of the invention if the mixture is dried as a loose bed or shaped body and comminuted to the required fineness in a separate subsequent operation, as well as if the mixture is sprayed into an air stream, for example a spray drying system.
- the invention is to be explained in more detail below in the form of exemplary embodiments.
- a standard prism solid was produced from the building material according to the invention thus obtained by mixing and shaping the building material with water in a water to building material weight ratio of 0.4.
- the water-gypsum mixture had to be mixed in a weight ratio of 0.6 for the comparison body.
- the test specimen produced from the building material according to the invention had a compressive strength of 22.5 N / mm 2 and a bending tensile strength of 7.0 N / mm 2 .
- the compressive strength of the comparison body made of normal gypsum was 14.5 N / mm 2
- its flexural tensile strength was 3.5 N / mm 2 .
- test specimen made from the building material was 6% after 1 hour, 10% after 3 hours and 12% after 24 hours.
- a mixture made from the building material according to the invention with a water / building material ratio of 0.4 was easy to process and gave warp-free standard prism moldings.
- a mixture of normal gypsum, made in the same mixture ratio, was very good difficult to process and resulted in a banana-shaped prism body with a longitudinal warpage of 18%.
- Embodiment 2 To produce a building material according to the invention, 1,000 g of gypsum are again mixed with 320 g of a 60% balsamic resin / spirit solution. The resulting mixture is sprayed in a trickle tower and dried. The resulting powder is mixed with 100 g dry short straw fibers and 600 g water. Standard prism solids formed therefrom have a compressive strength of 9.0 N / mm 2
