The upper coatings on the roads every day are subjected to strong loads, the number of pedestrians on the sidewalks and carriers on highways increases from year to year. Therefore, recently, issues of durability and dirty repulsion are facing manufacturers of concrete and paving slabs most acute. Concrete products are made of mineral raw materials, and therefore they have a heterogeneous porous surface. Taking into account the features of production, the specifics of mixing materials, various sections of concrete surfaces can have different sucking ability. Thanks to modern technologies, the cement activators and additives that optimize the capillary structure of concrete have been developed relatively recently. Such additives allow you to create concrete road surfaces, sidewalk tiles of improved quality and good protective properties. Of course, the release of modern mixtures is impossible without new concrete construction equipment. Given the needs of the market last year, a new planetary concrete mixer was launched into serial production. An increase in the performance of the concrete mixer was achieved due to the new geometry of mixing blades. This design successfully passed hydrodynamic tests. The supply of cement, additives and water into the concrete mixer occurs centered, which contributes to their uniform distribution and reduces mixing time. An increased number of lobes, provides greater productivity, since a larger number of mixing processes are performed in one cycle. Due to interchangeable modular parts, you can make changes to the configuration of a concrete mixer, for example, to reconfigure loading and unloading areas. For quick and effective cleansing of the mixer, a new automatic washing system was created: according to the radius, after the same distance there are four tanks with water with a three -dimensional direction of the jet.
In addition to high operational characteristics to road surfaces, and especially for paving slabs, high aesthetic requirements are presented. New German production line for concrete, includes fifty shades. Now you can create decorative concrete products and paving coatings that will approach any design. A liquid dye enters the solution of dispensers, connecting to other components in the mixing process, it gives the concrete mixture a given shade. With the help of modern solutions and unique chemical compositions of dyes, you can achieve accuracy of color, resistance, homogeneous distribution of dye in the mixture. Another innovation of recent years in the field of decorative concrete coatings – the use of fiberglassed, which can be added to almost all concrete mixtures, without changing the recipe for their preparation. The mosaic surface looks very impressive. Glass granules can be completely different colors and sizes, you can create plain flickering surfaces. Multi -colored paving stones are especially suitable for suburban construction. Glass granules in concrete coatings are quite strong, resistant to mechanical damage, they do not crack, do not split, and do not change color over time. Such resistance to the external effects of granules provides a special plastic shell of the enamel type. Granules at the end of the production cycle are polished, which in the process of mixing with the solution provides good adhesion to concrete.
