On 20 &ndash; 22 June Dyckerhoff presented its newly developed low-carbon cement Dyckerhoff Weiss BLUE STAR&nbsp; during the Ulm Concrete Days
This pozzolan cement was approved by the VDZ in mid-June with the standard designation CEM IV/A (P) 42.5 R and has since been included in the delivery program of the Am&ouml;neburg plant
around 15% less CO2 is released during the production of Dyckerhoff Weiss BLUE STAR
Dyckerhoff's expert team have been working on alternative input materials for white cement production for some time in order to reduce the CO2 footprint
natural pozzolan in particular proved to be suitable input materials to replace clinker
The interaction of the silicic acid with calcium hydroxide (cement) and water leads to a pozzolanic reaction
Dyckerhoff WEISS has been giving new impetus to building and designing with concrete
By differentiating the types of cement it is possible to offer cement solutions for the optimal operation of various application
types of cement with a higher fineness and thus higher performance (52.5) were provided
which optimise the cement content in the customer recipes through the use of different fillers
Solutions are now being developed that will also transfer white cement to a CO2-efficient future while maintaining the product's well known brightness levels
