Development of low-carbon cement providing improved durability in concrete structures

The objective of the project is to provide a basis for the use of a very environmentally friendly construction cement (Norcem Lavkarbonsement) in concrete for buildings, that will be competitive with respect to price compared to today's less environmentally friendly cement products. This will be achieved by maintaining the durability in concrete with the low-carbon cement at the same level as with today's main cement product in Norway. The minimum requirement for obtaining service life is provided in the concrete standard as deemed-to-satisfy requirements. In the project, alternative 'life cycle methods' will be developed to secure the required service life for a concrete building structure with the low-carbon cement.

The Lavkarbsem project has two main goals:

• Development of low-carbon footprint cement but without an increased carbonation rate.
• Enable the use of service life prediction instead of deemed-to-safety approach.
