New, already known to generations of high-quality cast flooring materials, ideal for installing floor heating, for example anhyment – cast leveling anhydrite screed, which can satisfy even the most demanding customer requirements.
A key role in the selection of suitable material already plays not only the quality of the materials and services that the company offers harga lantai kayu, but also the method of processing, speed of execution and not least financial cost, which also has the effect of constantly rising prices of raw materials and energy.
Previously used screed is already being replaced with new technology
The very designation concrete screed forms of human association with something technically very neatly executed. The concrete screed is a mixture of cement, aggregate and water, which is produced either directly at the construction site in common construction mixer, or in the concrete industry as industrially produced cement screed. The prepared mixture is poured into the space realized floor structure and often manually smoothed to the desired plane. For optimum strength characteristics of the final floor it is also necessary to place to spawn more additional reinforcement – steel, steel mesh.
Meet the requirement for flatness of the surface of the floor structure, when using moist mixture of superhuman power. Usually, the surface should have leveled with a suitable leveling compound. This brings additional costs.
With its use can not only reduce heating costs, but also the height of the floor songs in new buildings or renovations. It is a mixture of calcium sulphate (CaSO4) is a self-leveling effect, which allows comparison of floor structures with a tolerance of 2 mm to 2 m lathes, thus creating a perfectly flat surface below the final top layer. Meet the requirements of CSN 74 4505 Floors common provisions. Anhyment create a perfectly flat surface below the final top layer. This eliminates the additional equalization and leveling floors. Due to the strength can be applied over underfloor heating has a height of 3.5 centimeters. The mixture has excellent fluidity around the pipes of the floor heating, and therefore there is a fast and uniform heat transfer in floor heating. On anhyment can be considered the most floor coverings (floating floors, parquet, tiles etc.).
Production takes place in a special facility at maltárnách group Českomoravský concrete or unique mobile technological devices that enable the production of these screeds almost throughout the country. This material is suitable for the construction of housing, office buildings, community facilities, and the like.
The main advantages of this material are fast and hassle free stowage, minimal changes in volume and quality of the resulting surfaces. Thanks to its properties anhyment is the ideal solution for the realization of floors with underfloor heating. For residential bathrooms, kitchens and similar material is suitable for use under the premise of protecting the surface of some type of insulation.
Higher efficiency underfloor heating using anhyment
Conventional cement screed Modern anhydtitový fry anhyment
Other changes and advantages over the old conventional cement screeds (concrete mazaninám) is that screed calcium sulphate are not reinforced networks. Namely strength reaches 20 (30) psi pressure, and 4 (5) MPa in tensile bending. These values are the main means of a standard test following the signs and after 28 days of production fry on a set of small bars (160 × 40 × 40 mm) according to CSN 13 4454-2. Also, reinforcement is not necessary due to the significantly lower shrinkage of the material (about 0.01 mm / m), but also is undesirable in view of directly formed chemical reactions between steel and calcium sulphate (CaSO4). Anhyment has a virtually stable spatial behavior, which allows restricted use of dilation.
Floor assembly without reinforcement
Most often, the floor consists of a flexible intermediate layer, a layer of flooring material anhyment and a wear layer. Generally, the screed calcium sulphate based on the elastic intermediate layer should have a thickness at least 35 mm, if instead only the elastic interlayer separating layer (e.g. oil paper), there should be at least 30 mm thickness. Using screed calcium sulphate instead of the conventional screed thus can save material layer thick 30-40 mm.
