Abstract

FIELD: construction.

SUBSTANCE: method of obtaining decorative construction products involves dosing the bonding substance, water, filler material, and their mixture, insertion of fibrous material, moulding and hardening. The fibrous material is in the form of twisted mineral fibres an on the moulding stage it is put in the mixture with formation of a dotted contour of the drawing on the surface of the product. The twisted mineral fibres in the product can be laid in parallel, as well as at an angle to each other.

EFFECT: increased durability of decorative construction products, made with dotted drawings on their surface.

Description

The invention relates to the production of decorative building products from concrete, reinforced concrete, gypsum, namely: a variety of plates, partitions, fences.

It is known to obtain a building material for cladding, including preparing a mixture of a binder, water, aggregate, animal fiber material, mineral fibers, molding and hardening stages [1].

There is also known a method of manufacturing cement composites, comprising dosing a mineral binder, water, mineral fibers, mixing them, laying the mixture with subsequent hardening [2]. Mineral fibers are located randomly in products obtained by this method. The method does not provide obtaining on the planes of the products of the dotted outline of the pattern.

The objective of the invention is to increase the strength of decorative building products made with a bitmap on the surface.

The technical result is achieved by the fact that according to the method for producing decorative building products, including dosing of a binder, water, aggregate, decorating fibrous material, mixing them, forming and hardening stages, a decorative fibrous material is laid in the mixture at the molding stage to form a dotted outline on the product surfaces . The decorating material is made in the form of twisted mineral dyed fibers. In the product, twisted mineral fibers are arranged parallel to each other. In the product, twisted mineral fibers are located at an angle to each other.

Figure 1 shows a part of a decorative plate having on the opposite surfaces a dotted outline of the same pattern; figure 2 shows a block having on opposite surfaces the dotted contours of different patterns; figure 3 presents a fragment of a decorative column with dotted contours of drawings at different heights.

The method is illustrated by an example of the manufacture of concrete (reinforced concrete) products. From Portland cement (GOST 10178-85) in an amount of 500 kg, crushed stone (GOST 8267-93) 1000 kg, quartz sand (GOST 8736-93) 730 kg, water (GOST 2373-79) 260 kg, a concrete mixture is prepared (1 m ³ ) Decorating material is prepared in the form of twisted mineral (glass, asbestos, basalt, etc.) fibers of various colors in the form of threads, ropes, bundles, etc. The use of organic fibers or mixtures thereof with mineral fibers as a decorating material is an equivalent technical solution.

Decorating material is laid in the molds for the manufacture of products so that a dotted outline of the pattern forms on the surfaces of the future product. Depending on the selected pattern, the twisted mineral fibers in the product can be located parallel to each other (Fig. 1) or at an angle to each other (Figs. 2 and 3).

The concrete mixture is laid in pre-lubricated with mineral oil molds with decorating material and compacted. Products in forms are stored at room temperature for 1 day. Then the products are removed from the molds and kept at room temperature until they reach the age of 28 days.

The method allows to obtain decorative building products with a dotted outline on their planes. Products obtained in this way can be used mainly in the construction of kindergartens, schools, sanatoriums.
