The port of Aalborg in Denmark is the first large-scale concrete construction project to be implemented using the cement-free Geoprime® binder solution developed by Betolar. IBF A/S produced low-carbon paving stones for the 1.5-hectare expansion of the trailer parking area of the country's fourth large port. IBF's 90-millimeter-thick paving stone solution consists of two parts.

Its base structure is completely cement-free Geoprime material where cement is replaced by side stream material from the steel industry. Cement is used in the six-millimeter-thick surface layer to ensure durability concerning frost and thaw. In the production of paving stones, as a whole, IBF uses cement 90% less than before.

A 1.5-hectare parking area with a capacity of 110 truck trailers has been built in Denmark's fourth large port. While taking care of the strength and wear resistance of the pavement, the goal of the project was to cut CO2 emissions. By using side streams, the product supports biodiversity and meets the global requirements of the circular economy.

IBF has prepared a CO2 emission calculation based on the requirements of the European construction standard (EN15804). The port of Aalborg can use IBF's calculation to document the reduction of its own CO2 emissions.
