There are many different types of mortar. Typically, a mortar is named after the binder used in the mortar (prescription mortars) or by compressive strength (functional mortars). Read about mortar in TEGL 37 published by Forlaget Tegl.

Mortar must meet the requirements of Eurocode 6, and the method of manufacture must be able to be documented for both factory-made and construction-site-made mortar. Factory-made mortar must be CE marked. For construction site-made mortar, all sub-materials (factory-made lime-adapted mortar, cement, etc.) must be CE marked.

Lime, limestone, raw lime

The chemical formula for lime is CaCO3 = calcium carbonate. Lime is also called limestone or raw lime. In Denmark, lime is found in large parts of the subsoil. The limestone arose when Denmark was long ago for several million years covered by a warm sea with a rich wildlife.

When the animals died, they sank to the bottom of the sea. Here their calcareous parts (bones and teeth) lay layer upon layer for thousands of years and with the pressure of the sea, the calcareous layer gradually formed. It has been proven that 1 meter of lime in the limestone layer corresponds to 18,000 years. In Faxe Kalkbrud, which is Denmark's largest, the limestone is over 70 meters thick.

The compressive strength of concrete is stated in MPa (Megapascal), eg 35 MPa. However, the compressive strength can also be stated without designation as eg 35. Bl.a. the concrete plants give compressive strength without designation. M is the abbreviation for mega, which means million. Pa is an abbreviation for Pascal. Pascal is the unit in which you enter pressure.

By examining the exposure class, one finds out what requirements are placed on the strength and durability of the concrete. The exposure class depends on the environment in which the building is constructed. This may, for example, be casting in a marine environment such as at the Great Belt Bridge, casting against the ground or casting indoors in dry air.
