A complete portfolio of solutions that contribute to reducing the environmental impact of concrete production

Concrete is far from being considered as a sustainable material, particularly due to the massive amounts of CO₂ emissions associated with the production of Portland cement. Amongst the various levers in the hands of the cement industry to control greenhouse gas emissions, the industry has a number of innovative technologies that will assist in reducing its carbon footprint. These include carbon capture and reducing the clinker/cement ratio.

One such approach is the use of secondary cementitious materials or SCM (such as blast-furnace slag, fly ash and natural pozzolans) to partially replace clinker in the manufacture of cement. This is a fundamental part of the strategy to reduce CO₂ emissions by 55% by the year 2030 and to achieve carbon neutrality by the year 2050.

Future concrete will be produced using cement with lower clinker content. However, the use of recycled aggregates in concrete production presents several challenges for the concrete industry. Mixes generally will demand increased water content to achieve and maintain optimal rheological properties and the slower development of strength at both early and late stages.

At MAPEI we are committed to improving the sustainability of the construction industry, while supporting our customers in this very dynamic environment. To this end, we have developed the CUBE system. This integrated approach helps the concrete industry in overcoming the difficulties of reduced clinker cements and aggregates of varying quality through the various phases: Production, placement and in situ. CUBE system actively helps the industry maintain its high standards while reducing the climatic impact.
