No house today is just made of stones. New materials and sizes expand the range of bricks. Stones come in many varieties. But they all fit together, since the formats systematically build on each other. The sizes DF (yesterdaynformat), NF (Normalformat) and the 2-DF checker. The medium format includes the stones from the 3-DF- up to the 6-DF checker. stones, that go beyond these formats, are called large format. They all have a height of 23,8 cm. What stone is used to build a house, depends on many factors, with. B. building codes or climatic conditions. Low density stones, light stones, guarantee good thermal insulation. Heavy stones offer good soundproofing and are also used for load-bearing interior walls. is crucial, whether a a- or double-leaf masonry is created. Wide bricks are used for single-leaf masonry, which are plastered. In the case of double-shell masonry, the outer shell consists of the facing brick.
variety of materials
There is a wide range of facing bricks, in terms of color and surface. However, the exterior design of a house is often stipulated in the development plan, so that not the entire color spectrum is available. Nevertheless, a large selection of stones remains. Smooth, evenly colored stones, colorful flamed, sanded stones or hand-moulded bricks, each stone gives a house its own character with the same external shape.
Efficient work is possible with large-format stones. These stones are provided with recessed grips, which allow easy working with the blocks. There are large formats made of all materials, from which the small formats are also made. Due to the evenly flat surfaces and the tongue and groove production, laying with little mortar in the so-called thin bed is possible. Large stones up to a weight of 25 kg may be processed by hand, if the weight exceeds this, laying aids are required, small cranes, be used.
Variety in facing bricks
To achieve a uniform appearance of a brick wall, is it important, to process stones from different containers. This creates a varied appearance of stone shades, island-like color patches can be avoided, that inevitably occur, if stones are only processed in pallets.
sand-lime bricks
This material is made from natural raw materials and siliceous aggregates, namely lime and sand, manufactured. The mixing ratio is 1:12. The mixture is pressed into blanks of the required size using fully automatic presses. At a temperature between 160 and 220 degrees Celsius, the blanks are hardened under steam pressure for four to eight hours. After hardening and cooling, the stones are ready for use.
clay bricks
become clay bricks, as the name says, fired from clay. Clay bricks have been around for more than 5000 Years. The principle of the ceramic firing process has not changed much to this day, however, production is largely automated and computer-controlled.
Clay bricks are available as solid bricks or as vertically perforated bricks. The latter have excellent thermal insulation properties and are produced in large and NF formats. There are mortar pockets on the faces of the stones, Grooves on the side surfaces enable good plaster adhesion. Interlocking vertically perforated bricks allow for rationalization when bricking up. Solid bricks are used as facing bricks in double-leaf masonry. They protect the inner wall from moisture. Solid stones are also available in special shapes as facing bricks or sole bench stones. The shapes are so different, the colors and structures of the brick surfaces are so diverse: smooth, handstrich, sanded or colored glazed.
Blahtonsteine
Countless air voids, encased in fired clay pellets, give expanded clay blocks their excellent thermal insulation properties.
Aerated concrete in handy block form or in large format – Fine-grain quartz sand, Lime and cement are the basic components, from which aerated concrete is made. A blowing agent creates the tiny air voids in the mixture. The base mixture is poured into molds and hardened. There are stones in handy formats and as large panels, which can only be processed with cranes.
