Limestone is an essential raw material
Nordkalk Parfill white limestone fillers are an economic way to replace some of the cement in concrete production. With limestone fillers the concrete will be lighter in colour with less variation and there will be less shrinkage.
Since limestone fillers can replace part of the cement content, the environmental load will be reduced. Limestone fillers result in more stable concrete quality, thus reducing the amount of rejects and improving durability, which leads to a longer lifetime for concrete structures.
Limestone fillers save cement, improve the quality of the concrete and reduce the environmental impact.
