gräfix 22
White lime hydrate CL 90-S
White lime slaked at the factory
(calcium hydroxide, Ca(OH)2)
gräfix 22 is used as a binding agent for mortar, plasters and other coatings and can be easily mixed in due to its fine distribution.
Furthermore, gräfix 22 is used for waste gas and waste water purification and as a versatile neutralising agent.

Lime for construction, industry and the environment
Around a third of all quicklime produced in Germany is supplied to the iron and steel industry, where high-quality lime products are used in the production of iron ore, pig iron and crude steel, removing unwanted by-products. Lime is also used in the extraction of iron and steel, gold, silver, copper and uranium, as well as in the manufacture of chemical products.
However, the lime industry's oldest customer is the construction industry.
Lime was already being used systematically by the Romans, who achieved an almost industrial standard in kiln technology. Today, lime is used as sand-lime bricks or aerated concrete in wall construction and holds the bricks together in lime-based mortar. As an aggregate, it is added to various building materials and improves the properties of concrete as an additive. Its building biology properties are dealt with separately. The use of hydrated lime in asphalt is a new addition to lime. According to American studies, the adhesion between the minerals and the binders as well as the ageing capacity (embrittlement) of the bituminous mortar is improved by adding hydrated lime to the asphalt. Hydrated lime in asphalt leads to more stability, fewer ruts, in short: to durable roads.
