gräfix 24
slaked lime
Factory-slaked quicklime (calcium hydroxide,
Ca(OH)₂)
gräfix 24 is a slaked lime based on calcium hydroxide and is used as a binder for mortar, plaster and other lime-based coatings.
Thanks to its smooth consistency, the slaked lime mixes in well and can also be used as a lime wash for ‘liming’ surfaces.

Lime for construction, industry and the environment
Around a third of the quicklime produced in Germany is used in iron and steel production. Lime products are used there, amongst other things, in the production of iron ore, pig iron and crude steel, and help to remove unwanted impurities.
Furthermore, lime is used in the extraction and processing of various metals, as well as in the manufacture of chemical products.
One of the oldest areas of application for lime is the construction industry. The Romans already used lime systematically and continuously developed the calcination technique.
Today, lime is used, for example, in sand-lime brick and aerated concrete. In lime-based mortars, it serves as a binder. Limestone is also used as aggregate for various building materials.
Hydrated lime is also used in asphalt. Studies show that the addition of hydrated lime can influence the adhesion between mineral materials and the binder, as well as certain properties of the bituminous mortar. Statements regarding stability, rutting and ageing behaviour should be interpreted in accordance with the relevant underlying studies and their test conditions.
