A cement mortar allows different types of application in the application

Cement mortar is probably the most frequently used building aid in building construction. In addition to masonry, it is used as a floor substructure and as a plaster for exterior and interior use. In some cases, it forms smaller foundations and serves as a universal adhesive for all concrete and stone components.

Fields of application and types of application

Cement mortar is a kind of universal adhesive and bonding agent for all building components made of concrete and stone. The main applications and applications are:

  • Grout for bricks made of stone, clay or concrete
  • Fixing mortar for window sills, door frames and lintels over doors and windows
  • As a cement plaster for exterior
  • As a cement plaster in the interior including damp rooms such as the bathroom
  • Cement mortar is the basic material, if Cement screed instead of floating screed or left u = cement screed or anhydrite screed] Antihydritic screed [link]
  • Cement mortar can serve as a foundation in a limited scope and dimension

Property adaptation through additives

The almost unmanageable range of possible mixing forms and additive additions is for everyone Application of suitable mortar. For the main constituents sand, water and cement additives are mixed in which alleviate or enhance the following properties:

  • adhesion and adhesiveness
  • density after setting
  • compressive strength
  • water resistance
  • moisture resistance
  • load capacity
  • optical structure
  • optical surface effect and coloring
  • elasticity, shrinkage and expansion behavior
  • Frost resistance
  • Soundproofing
  • Thermal insulation
  • Processability and pot life
  • Drying and setting time
  • Required application strength for the required adhesion and stability

Mechanical function and load capacity

Mechanically, cement mortar must withstand the different loads during its use. For this you are divided into five groups according to the so-called masonry standard DIN 1053. Only the two highest mortar classes (MG III & MG IIIa) are pure cement plasters. A load-bearing cement mortar must carry at least ten Newton per square millimeter, in the highest class twenty Newton per square millimeter.

Special lightweight and thin-bed mortar can reduce the processing in terms of volume and effort in accordance with structural requirements. Special mortars without supporting tasks, such as sewer and manhole linings, have to stick stronger than supports. In the construction of a conventional and average family house, between twenty and thirty types of mortar are used.

Tips & TricksFor the search and selection, pay less attention to the messages and promises of manufacturers regarding convenient and easy processing. The technical and static properties determine the suitability.
