In Germany, this still applies solid masonry house as the most solid form of a residential building.

There are, however, great structural differences, and these in turn depend not least on the brick used.

bricks differ in material, format and method of processing - There are many variants available. The possibilities offered by the various bricks are correspondingly diverse.

We give one here Overview of common bricks and show which solutions can be realized in construction.

Building bricks

Brick-fired bricks are denser than simple bricks or bricks. They are therefore sufficiently weather-resistant to design a fair-faced masonry on the exterior facades.

Bricks are going out formed from clay and clay, dried and then fired at high temperatures in ovens.

Characteristic is the brick-red color, but the spectrum reaches today over the full range of yellow over orange and red to a deep blue.

The real difference between the different brick types, however, lies in their shape, in the relationship of clay and clay and in the temperature of burning.

easy Adobe bricks or bricks are fired at relatively low temperatures around 900° C, This and the lower clay content creates a relatively porous structure, which is also not very pressure-resistant. Because the Pores easily absorb water, plaster mud brick or by one Facade cladding against the weather to be protected.

Clinker facing bricks or facing bricks can be used to create very attractive exterior surfaces. In this example you can also see that brick red is far from the only conceivable color

Unlike the clinker. The higher proportion of clay with his salary at Aaluminium- and silicate compounds and with about 1200° C higher firing temperature provide a denser structure that is more stable, more resistant to pressure and more resistant to weathering.

That is why clinker bricks are used to build exposed masonry or to set a wall in front of it other stones a clinker facade as a second wall layer.

For this purpose come too Clinker facing brick used, which are very precisely made, allow a closer joint pattern and thus less rustic effect than a traditional brick wall.

Plane tiles with their ground bearing surfaces are very easy to process precisely because they can be put into thin-bed mortar.

The desire for more rational construction techniques is due to the development of Planziegeln. These are usually gRössere Steinformate, which fit on the front sides with incorporated profiles into each other and at the top and bottom are ground plan.

This form allows easy processing with thin-bed mortar and is therefore also found in self-assembly systems, with which builders build the shell in-house.

Planziegel are usually designed as a perforated brick. Hollow tiles have - mostly vertically extending - cavities, on the one hand reduce weight and thus simplify the handling of larger formats, but on the other hand also one insulating effect have. In some perforated bricks, the cavities are additionally filled with insulating materials

natural stones

Bricks, limestone, natural stone, aerated concrete: bricks at a glance: limestone

A wall of regularly hewn natural stones. Soilche constructions are because of the high price in the new building hardly found today.

While bricks traditionally have their largest spread in the relatively low rock north German lowlands had been built with natural stones in the vicinity of accessible rock deposits.

For the production of a natural stone were and become pieces of the cut either in the desired format or sawn today more often.

Natural stones are often used as ornamental or functional elements. Here a brick crown made of natural stone on a garden wall made of bricks.

Because natural stones like Granite, marble, porphyry, sandstone, limestone or basalt have quite different properties, they can not be assigned to specific purposes and constructive solutions.

However, common is natural stones in the Relationship to other bricks mostly high pricewhich only puts itself in close proximity to the mining sites by the then lower transport costs.

The natural stone slate is usually used as a plate material because of its easy cleavage: for the cladding of facades or as here to cover a badger.

Natural stones are today mostly in visible areas as used on the exterior facade, In addition, individual components such as FWindow benches, door and window surrounds made of natural stones made, as well as ornamental walls or small outdoor horticulture.

This is where the attractive appearance of many natural stones comes into their own and puts the extra costs of industrial bricks into perspective.

On Special case among the natural stones is the slate, Since this rock can be easily split into plates, it is often in the vicinity of the deposits for Roofing and cladding used and determined in these regions the traditional townscapes.

aerated concrete

The very regularly shaped plan blocks made of aerated concrete can also be easily processed with thin-bed mortar, just like the flat roof bricks.

Aerated concrete, also called aerated concrete, is made in an industrial process fine lime, quartz sand, cement and water manufactured. Aluminum powder added to this mixture becomes, reacts with the remaining components and forms fine gas bubbles.

After completion of this process, the aerated concrete will be under Influence of heat, pressure and water vapor cured.

Aerated concrete is not too weatherproof. Therefore, such a shell needs at least a plaster.

The result is a lightweight, porous building material that Easy to work with and good thermal insulation properties has. The various formats - from flat plates or small blocks to large blocks - are made by cutting the hardened raw material.

An aerated concrete wall can also form the inner shell of a functional wall. Then an exterior insulation is followed by a visually attractive brickwork made of limestone or clinker.

When cutting results in very flat surfaces, so that aerated concrete in the thin bed process can be walled. Aerated concrete is therefore and because of the low weight and a common wall building material in self-assembly, In addition, aerated concrete can be processed with simple tools such as hand saws or rasps.

The blocks are available in different pressure resistance levels, sometimes with steel reinforcement.

Because the material only a little weather-resistant is, it often comes along with external facades a covering, a bricks made of brick or sand-lime bricks or as inner layer of a double-shell wall or functional wall for use. This also improves the sound insulation, which is often insufficient for pure aerated concrete components.

A special application of aerated concrete is the use of large slabs as a solid roof, which does not require a traditional roof truss and offers good summer heat protection.

Due to their regular shape and their characteristic white color, sand-lime bricks in the right environment are very well suited to exposed masonry.

Sand-lime bricks are made from one Mixture of quicklime, quartz sand and water manufactured.

After the lime has reacted with the water, the stones are pressed and then Hardened by steam, pressure and heatt.

The result is very dense brickswho at her characteristic almost white color are recognizable.

Sand-lime bricks offer due to their Density a good soundproofing, Since they are very regular and accurately shaped, they are suitable for exposed masonry - because of its weather resistance also on facades.

This often happens too specially structured bricks made of sand-lime brick whose surface is supposed to make the masonry even more attractive. Sand-lime bricks are also pressure-resistant and loadableThey therefore also serve as building material for load-bearing walls.

Since her Thermal insulation properties less convincing, Sand lime bricks are becoming common for exterior walls double shell with core insulation or used as a superior facade in front of a insulated construction.

Lightweight concrete bricks

A bodyshell made of pumice concrete. Just like aerated concrete, this building material must be protected from the weather with plaster, cladding or bricklaying.

Under this keyword, various bricks can be summarized, the Concrete with a light, porous aggregate consist.

Both Aggregates may be expanded clay spheres act as they are used in plant breeding, but also around pore-containing rocks such as pumice.

Lightweight concrete blocks are easier to lift and to work therefore More process-friendly than denser bricks, At the same time they offer quite good insulation properties.

(Caricature: Daniel Fuhr,

As exposed masonry lightweight concrete blocks are usually not. You need to plastered, clad or provided with a bricklaying become. Since they are also more absorbent than dense bricks, care must always be taken to carefully seal the exterior walls made of them.

Walls made of pumice or related stones are - like many porous building materials - less well, to anchor objects in it.
