Milling concrete

Concrete can be machined in many ways. In new construction projects, but also in renovation projects and other work with concrete milling is an important processing option. Below you will find information about milling concrete.

Already shaping during casting

Concrete has long been one of the most important building materials. Without concrete, many structures that are taken for granted today could not be realized. Not only the excellent values ​​for the load of concrete speak for the building material. Even the casting of concrete can be adapted in great detail to individual needs.

Nevertheless, concrete usually has to be further processed

Many planning specifications are already taken into account during the implementation. But not always that is possible. Then different mechanical processing techniques of concrete come into play:

  • Sawing and cutting concrete
  • Grinding concrete
  • Polishing concrete
  • Sandblasting of concrete
  • Milling concrete

Milling concrete

Milling concrete is one of the most common machining techniques. First, however, a distinction must be made here: concrete surfaces can be milled off over the entire area, as well as the milling out of certain areas of a concrete body is a typical milling of concrete.

Mill full-surface concrete surfaces

Solid surfaces, for example, must be milled when the top layer has to be removed to polish the entire surface of a concrete floor. But also in renovation, surface milling of concrete is a crucial step, for example, the roughening of concrete for further processing. For concrete floors, milling machines are available, which are pushed over the concrete surface. If, on the other hand, you want to mill walls or even ceilings made of concrete, you will need to use hand tools.

Milling and sawing slots

More often parts have to be cut out of concrete. At the forefront is the milling of slots for the laying of pipes or water pipes. Depending on the slot cutter that is used, you can mill different depths into a concrete element. Of course, there are also slot machines as large machines, but commonly used for slot milling hand machines.

Reinforced concrete can not simply be milled

Especially in modern buildings, the milling of concrete requires a lot of expertise. Not every concrete element can and may be milled at will. On the one hand, it must be ensured that a reinforcement (steel mats or irons, for example) is always sufficiently sheathed in concrete and that not too much is removed. It's not just about directly influencing the load capacity. Rather, the concrete explicitly protects reinforcements made of steel, especially against corrosion.

The tool for milling concrete

Machines for surface milling

For the milling of concrete special tools and milling have developed over time. So concrete is usually milled with so-called diamond segments. This is, for example, an exact diamond grain, which is specially connected with plastic. These segments are then mounted on the front plate, which rotates during milling. However, such diamond segments are also correspondingly expensive.

Machines for milling slots

For milling slots, on the other hand, either star milling heads or diamond disks are usually used. The latter saw the concrete but rather. In contrast, star milling heads are mounted twice on the slot cutter and move in opposite directions. Such slot cutters can also be used to mill or abrade a facade. The boundary between milling and grinding is almost fluid here with concrete.

Tips & Tricks

Already during the planning, the material properties of a concrete element are decided. The casting of a concrete mixture defines the properties of tough to fluid concrete and thus also has a later influence on how a concrete can be milled and otherwise processed.
