Granite crushed stone is a fairly common building material that belongs to the bulk class, the size of the grains is more than 5 mm. It turns out when the crushing of large granite with a further scarry of the resulting product. Before considering the application, it is necessary to familiarize yourself with the main characteristics of this building material.The first thing you should pay attention to is the breaming of crushed stone. This parameter characterizes the content of the grains of a triangular or needle -shaped shape, which increase the consumption of the connecting component. The grains of the correct shape are laid as denser as possible, which reduces the intermediary void and, accordingly, reduce the consumption. In addition, the high density of cuboid grains increases the strength. No less important characteristic – radioactivity of crushed stone.
The fact is that granite itself has a slight radioactivity. Therefore, before use, this material should be checked for compliance with all radioactive security standards. The use of dirty crushed stone is also permissible, but mainly for the construction of suburban roads. Another important characteristic is frost resistance, granite gravel should withstand several hundred freezing cycles.
Since the grains of granite crushed stone have a different shape and size, the use may differ. In any case, this material has a rough surface and grows well with cement. The largest grains can already be considered a stone, or a boot, the size of the rib in this case can be 30 cm. Such material is well suited in creating retaining walls, in creating a foundation or fencing. Grain up to 70 mm in size is applicable where it is about large volumes of concrete or, like the flooring of the railway tracks.
Crushed stone with grain of 20-40 mm is applicable when creating strong concrete structures or when pushing the bases of roads. If the grain size does not exceed 8-15 mm, the building material has a small fraction and is most often in demand. Again, in the production of concrete, mainly during the construction of bridges or laying road and airfields. But there is a smaller fraction with grains up to 5 mm. It is used in creating most reinforced concrete structures or to sink sports grounds, and in the creation of garden landscapes, such crushed stone is also in demand.
