Stone in the industrial
Massive stone used by masons. Natural stones at a thickness of 8 cm are referred to in the natural stone DIN 18332 as plates and about 8 cm and stone work. Produce massive work, call the masons work work, they therefore provide a work, building stone, ago. The stone processing and the corresponding tool used by masons differs considerably according to soft rock or hard rock.
Building stone are workpieces. If all visible surfaces machined, one speaks of the well- machined workpiece. The non- visible surfaces of a workpiece usually remain rough and are leveled according to the requirements only in the surface.
The term stone is incorporated in the term natural stone, for stone or stone is any stone found in nature (eg, boulder, reading stone, rock deposits ). Geologists and mineralogists designate stone differently, namely as always rock.
Cast stone / artificial stone
Concrete stones are man-made building stone, also called artificial stone.
In addition to cement as a binder and optionally various auxiliaries, additives and fillers are predominantly gravel for the production, so uses natural rock as aggregate.
The surface of the work pieces can be processed in various ways to obtain, for example, the following structures: quarry, flamed, bush-hammered, embossed, cut, ground or polished.
Flamed surfaces are now often also brushed to obtain a more comfortable, lower-maintenance surface.
