Cements with reduced clinker content

(Clinker content ≤ 70%)

In line with our claim, “SUSTAINABILITY THAT WORKS,” we offer a wide range of clinker-reduced products. We achieve a reduction in clinker content in cement by using alternative raw materials. Discover our range of clinker-reduced products.

Environmental Product Declarations (EPDs)

EPDs with good GWP values are available for our cements and selected concretes. EPDs, or Environmental Product Declarations, are standardised documents that present the environmental impact of a product throughout its entire life cycle in a transparent and comparable manner.

CSC certification

Our German cement plants and many of our companies have been awarded CSC certification. The value of the CSC certificate lies primarily in its recognition by international sustainability assessment systems for buildings. These systems include BREEAM, LEED and DGNB, which recognise the CSC certificate.

CI4C

The CI4C consortium is building the first research and development facility that almost completely captures CO2 from the production process. This is a crucial step toward more climate-friendly cement production.

meca-clay

Together with the plant manufacturer thyssenkrupp Polysius, we have developed the meca-clay technology for the production of reactive pozzolanic cement additives through the purely mechanical activation of clays. This enables all types of clays to be converted into highly reactive cement additives without the use of fossil fuels —using only electrical grinding energy and resulting in reduced CO2 emissions from the raw material.

Concrete with improved sustainability features

By using clinker-reduced cements and other additives in concrete, the environmental footprint of the building material can be improved. Upon request, we can meet all CSC CO2 levels with our concrete and cement products — tailored precisely to your needs.
