Introduction of Concrete Screed:
A concrete screed is a mixture of water, cement, sand, and fine aggregates. The grain size of fine aggregate is 4 mm.
Concrete screed is used to elevate floor level as per finishing requirements. Screed provided a surface suitable for installing the desired flooring.
Screed is a type of plain concrete but the key difference is that we use fine aggregates instead of coarse aggregate like gravel.
You can see the below image of concrete screeding in the bathroom.
Normally it is a thin layer of concrete that is typically poured over a base floor to help form a smooth floor coating to provide a strong foundation for the top floor.
The thickness of concrete screed is typically varied from 100 mm to 150 mm.
Screed is a thin layer of material that is placed on top of a substantial subfloor. For the most part, screed comprises of cement and fine sand, however where a more industrial version is required, coarse aggregates can be used to form a thicker layer. The layer of screed is frequently covered with an embellishing finish, yet sometimes, for example, such as distribution centers, it is left bare to proceed as the finish itself. This is normally done in conditions where scuffs and marks are to be expected, but it can be utilized as a stylish flooring choice as well.
Sometimes we can use conventional plain concrete for screed.
Applications of Concrete Screeding:
- A concrete screed is used to raise the floor level.
- Screed is used to install a waterproofing membrane.
- Screeding is done to level the concrete surface.
- Screeding is used to the provided base surface to finish floor coverings such as carpet or tiles.
