Limestone powder is the most widely used building material in the world. This status is the result of the good physical and chemical qualities of limestone. Lime is stone, therefore it does not decompose, shrink or expand.
Nordkalk’s limestone powder products made of the white marble in Pargas are used in products, in which high quality and white colour is required such as white plasters and mortars, white concrete facades, in colourful facings and e.g. in the white substance used for road markings. Other Nordkalk lime fillers are widely used raw materials in different construction industry products such as concrete, tiles, roofing felt and fibre cement board and in mortars and levelling compounds.
Quicklime is needed as a binding agent in lime sand bricks, and slaked lime in all types of plasters and levelling compounds.
