Trade Journals for the Concrete Industry

Efforts to reduce CO2 emissions are affecting all of humanity and are dominating our everyday lives like never before. In the construction sector, cement, the binder required for the production of concrete, offers the greatest potential for savings and is therefore often the focus of discussions. The production of the strength-forming main component clinker requires large amounts of thermal and electrical energy and causes the majority of the CO2 emissions of the cement. Cement manufacturers are therefore developing new binders with less clinker and more clinker substitutes. In view of this development, the industry fears a "dilution" of the cement combined with lower strength and reduced durability. In addition, the question arises which influence these new cements have on the performance of the currently used concrete admixtures and on the production and quality of products made of semi-dry concrete.
