  2. Self-leveling concrete - Wikipedia

    en.wikipedia.org/wiki/Self-leveling_concrete

    Self-leveling concrete was invented in 1952 by Axel Karlsson from Sweden. The first product was a combination of wood glue, fine sand and cement with additives. [1] It was called flytspackel, which directly translates to "floating putty". The term self-leveling can be traced back to a patent applied by the company Lafarge in 1997. [2]

    en.wikipedia.org/wiki/Concrete_leveling

    In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.

  6. Self-consolidating concrete - Wikipedia

    en.wikipedia.org/wiki/Self-consolidating_concrete

    Self-consolidating concrete or self-compacting concrete (SCC) [1] is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until the concrete sets).

  7. Screed - Wikipedia

    en.wikipedia.org/wiki/Screed

    A power concrete screed has a gasoline motor attached, which helps smooth and vibrate concrete as it is flattened. After the concrete is flattened it is smoothed with a concrete float or power trowel. A concrete floor is sometimes called a solid ground floor. A plasterer also may use a screed to level a wall or ceiling surface in plasterwork.

    After drying the wood, it is planed into long fibres in a wood wool machine. The fibres are then mixed with the binding agent (caustic magnesite or cement) in a water solution, in a mixer. Wood wool boards which are bound with magnesite are easily distinguishable by their beige colour. Boards which are bound with grey cement have a greyish colour.
