Innovative new product reduces emissions by 40%

Finnsementti, a CRH Company based in Finland, has launched the country’s first ever low-carbon cement. The innovative new product, known as Kolmossementti, will enable concrete producers to reduce the carbon emissions of products supplied to construction projects across Finland.

Kolmossementti is the outcome of extensive long-term research and product development, which has resulted in a cement that reduces emissions by 40%. Finnsementti achieved this by reducing the clinker factor of the cement by using Ground Granulated Blast Furnace Slag (GGBFS).

The long-term outlook for the cement market in Finland is centred around an ambitious Government target of carbon-neutrality by 2035. As such, this new low-carbon product will help Finnsementti to meet the increasing demands of the Finnish construction industry for more sustainable products and solutions.

Kolmossementti is suitable for a wide variety of applications and can already be seen in use in a new 24-storey residential building in Vuosaari, Helsinki, the base slab of which is cast from more environmentally friendly concrete developed by Finnsementti’s sister company Rudus using the new Kolmossementti product.

CRH is committed to playing its part in delivering a carbon-neutral future and has set an ambition to achieve carbon neutrality along the cement and concrete value chain by 2050. This includes an industry leading target for our cement plants to reduce emissions to 520kg CO2/tonne cementitious product by 2025.

CRH’s products and solutions have an important role to play in helping to accelerate progress towards a resilient, net-zero built environment and we have set a target of achieving 50% of revenue from products with enhanced sustainability attributes by 2025.
