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]
Skim coat/broom finish concrete resurfacing – Restore and protect damaged, pitted, flaking and stained concrete back to the look of a new concrete surface. Concrete regrading & leveling – Repair and level concrete surfaces that have settled.
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).
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.
Concrete has a limited lifespan between batching / mixing and curing. This means that ready-mixed concrete should be placed within 30 to 45 minutes of the batching process to hold slump and mix design specifications in the US, [15] though in the UK, environmental and material factors, plus in-transit mixing, allow for up two hours to elapse.

Autogenous self-healing crack. Self-healing concrete is characterized as the capability of concrete to fix its cracks on its own autogenously or autonomously. It not only seals the cracks but also partially or entirely recovers the mechanical properties of the structural elements. This kind of concrete is also known as self-repairing concrete.
The material itself which has been flattened with a screed (screed coat). [ 2 ] [ 3 ] In the UK, screed has also come to describe a thin, top layer of material ( sand and cement , magnesite or calcium sulphate ), poured in place on top of the structural concrete or insulation, on top of which other finishing materials can be applied, or the ...
