Road construction

Cost-effective material for construction and binding

Our quicklime and hydrated lime makes optimal material mixes possible, such as those for concrete and asphalt. As subgrade, our KFN lime product nekasol® 2 takes care of stability and longevity in the construction of highways and roads. It also renders most of excavating and the delivery of subgrade material unnecessary. KFN lime is also an indispensable ingredient of surface courses: nekapur® 2 enhances the binding between bitumen and gravel in pavements.

Binding agent and construction material

Sustainable construction with lime

KFN lime used as a binding agent is an indispensable ingredient in the production of construction material such as sand-lime bricks. Sand-lime bricks made from our high-quality fine white quicklime product nekafin® 2 lets builders construct buildings that are very well insulated and a healthy indoor climate. Additionally, KFN hydrated limes are the basis of lime mortars and lime plasters. They are used for insulation, for surface designs, as screed or in tiling. When restoring historic buildings and in the ecological building area, traditional wood-burnt marble slaked lime is indispensable.

Steel production

Lime improve the quality

Steel producers prefer our highly reactive lump lime for its very low content of minor components. nekafer® 15 removes impurities from molten steel. The addition of lump lime helps to bind sulphur, phosphorus, manganese and silica into the slag.
