Description

The The invention relates to a brick.

bricks are used to wall masonry formations for walls of buildings, especially exterior walls, interior walls and walls Basement walls; and also for freestanding walls, used: The bricks are in the brick wall mortified at their joints and thereby firmly connected by the hardened mortar, at least at the bed joints of superimposed stone layers. At the butt joints between stones can also be a positive connection such as a toothing or tongue and groove and then a mortar the butt joints omitted.

As materials for bricks in addition to the traditionally used natural stones, especially magma bricks such as granite or sedimentary rocks such as limestone (CaCO ₃ ) or sandstone or metamorphic rocks such as marble, to name a few, nowadays mostly artificial or man-made bricks in use. In addition to bricks, mainly sand-lime bricks and bricks made of cellular concrete or lightweight concrete are common in the construction of buildings and houses. An overview of natural stones and ceramic and mineral bound building materials are for example the book Scholz / Wiese - "Baustoffkenntnis", 15th edition, 2003, Werner-Verlag, page 1 to page 99 ,

Wall bricks Be made of clay, loam or clayey masses with or without additives shaped and fired.

Sand-lime bricks are bricks made of fine lime and siliceous aggregates. For this purpose ground quicklime (quicklime, calcium oxide, CaO) is produced by burning limestone (CaCO ₃ ) and mixed with siliceous aggregates or sands with a small amount of added water. During interim storage, the burnt lime deletes lime hydrates (slaked lime). Then the mixture is brought in a post-mixer to press moisture, and stone blanks are pressed. The stone blanks are then cured in autoclaves under saturated steam pressure at about 16 bar and at temperatures of 160 ° C to 220 ° C. During hardening, the lime reacts with the silicon oxide of the aggregate or sand, which has been digested by the hot steam, to give calcium hydrosilicates without carbonation. The aggregate or sand grains are thus in Kalksandsteinen a hardened binder, which consists of calcium hydrosilicates, but does not contain calcium carbonate, connected or cemented together. The structure in sand-lime bricks is not porous, but there is one, also in the appearance of the stone, closed binder matrix between the aggregate grains before.

Concrete is an artificial stone made from a mixture of cement, aggregate and water by hardening the cement-water mixture. Cements are hydraulic binders and consist mainly of calcium silicates and calcium aluminates, which react with water to form corresponding hydrates. Lightweight concrete has a lower dry bulk density and is produced by lightweight aggregates and / or porosity of the concrete structure (cf. Scholz / Wiese - "Baustoffkenntnis", pages 179 to 189, pages 247 to 269 and pages 337 to 342 ).

bricks be made of aerated concrete by mixing quartz-containing sand or other quartz-containing additives or flyash as a supplement and quicklime and / or cement as a binder, blowing agent and Water and possibly additives produced. As a porosity agent Fine powder or a fine-grained paste of aluminum is added. The pores are created by liberated hydrogen. The raw material mixture is poured into molds and formed by puffing up the mixture the molding in the mold. The molding is then in a saturated steam atmosphere at about 190 ° C hardened. The pore walls and the hardened binder between the grants consist in aerated concrete blocks essentially of calcium silicate hydrate. Aerated concrete blocks are not heap-porous, but they are around a closed by the binder structure, however, very many and sometimes very fine gas pores in the binder matrix having.

The European Standard DIN EN 771-3 and the German application standards DIN 18151, 18152, 18153 and 20000-403 describe the composition which Properties and use of concrete bricks (normal and lightweight concrete), which apart from normal and light aggregates only Contain cement as a binder. As normal aggregates become prevalent Natural gravel and natural sands used.

Lightweight concrete bricks according to DIN 18151, 18152 and 18153, consist of concrete of maximum dry weight density of 2000 kg / m ³ , in which the starting mixture in addition to the concrete concrete components cement, aggregate and water are also added light aggregates according to DIN EN 13055-1, For example, expanded clay, expanded slate, expanded glass, pumice or boiler sand. The concrete is pressed into molds and usually subjected to a heat treatment for hardening. The lightweight concrete bricks usually have a hovwerksporige structure, wherein the aggregate grains are coated with the cement paste and in dense storage in small, more punctiform areas touch and there on the hardened cement or cement paste are bound together as a binder (see. Scholz / Wiese - "building material knowledge", see, pages 92 to 98, 209, 338 to 339 )

It is also known to use Baukalke as a binder for masonry mortar and plaster, as well as white and for lime paints, fine lime also for the production of limestones (see. Scholz / Wiese - "Baustoff knownis", so, pages 166 to 173 ). For construction limestones, a distinction is made, for example in DIN EN 459, air limescale and hydraulic limescale.

Air lime is essentially slaked lime or calcium hydroxide or hydrated lime Ca (OH) ₂ prepared by quenching quicklime (CaO) prepared by burning limestone or calcium carbonate CaCO ₃ with water (H ₂ O). The lime limestone gets its name from the fact that when hardened the quenched lime Ca (OH) ₂ reacts with water and carbon dioxide from the air, which together form carbonic acid (H ₂ CO ₃ ), to hardened lime (limestone CaCO ₃ ) and water exothermic. Hydraulic limestones contain constituents which harden cementitiously by reaction with water, as well as water-hardening and hardening clay-based hydraulic compounds consisting essentially of silicic acid (SiO ₂ ), alumina (Al ₂ O ₃ ) and iron oxide (Fe ₂ O ₃ ) contains.

While of the filling process the mixture is already pre-compacted. The final compaction the mixture to the stone molding is preferably carried out by high Vibration energy and by the introduction of press punches in the stone form.

To This compression process during pressing is the pressed stone molding (Grünling, Pressling) automatically demolded, i. the shape is taken from the stone compact, which lies on a base, removed, and, in particular via different conveyors such as B. conveyor belts, in a drying chamber or curing chamber spent.

In The drying chamber is the stone moldings over a period up to several Days (up to a week, usually shorter) left and stored for curing. In the drying chamber prevail for this curing process typically normal temperatures between 10 ° C and 45 ° C and humidities of typically 50% and 100%.

During the Drying and curing process reacts the contained binder, in particular its lime content and possibly cement content with the mixing water from the mixing process and / or the Carbon dioxide of the air and forms a solid structure for binding of the grains as now hardened Lime or cement as a binder in the brick. The remaining water Evaporates with time, until the equilibrium moisture content in the brick is reached.

To curing The bricks are transported out of the drying chamber and in the open air or in a hall or warehouse up to theirs Delivery and use stored.

It is used as aggregate aggregate aggregate for the starting mixture with a proportion of grit and sand from crushed limestone, especially pure limestone (CaCO ₃ ) and / or dolomitized limestone (CaCO ₃ · MgCO ₃ ), and / or natural gravel and sand (predominantly Quartz SiO ₂ ) from 60% by weight to 90% by weight, the stated weight percent being based on the dry weight of the starting mixture without water. The aggregates have granulations of 0 mm to 16 mm, preferably 0 mm to 8 mm. The grain sizes are determined in particular by sieving methods and corresponding grading lines or sequences of sieve steps.
