Reducing carbon dioxide emissions by using concrete admixtures 

Sustainable cement production is an issue that is getting increasingly important for the construction industry. Manufacturers can reduce carbon dioxide emissions during cement production significantly by replacing part of the clinker with fly ash. Until now however, the further processing of such cement often resulted in inferior concrete qualities. Our solution: the Glenium SKY hyperplasticizer. Its utilization enables manufacturers of ready-mix concrete to produce a high-strength, durable concrete out of cement containing up to 50 percent fly ash. This is the result of a joint research project by experts from BASF, Evonik and the Technical University of Munich.

Customer requirement		Our solution
High-grade ready-mix concrete with a large fly ash proportion		Glenium SKY®, a hyperplasticizer for ready-mix concrete Ensures high quality concrete with a fly ash proportion of up to 50 percent

Reduced energy demand and less maintenance work

Glenium SKY also increases the concrete’s workability. At the same time, the plasticizer ensures a high early strength development. The high durability of the concrete also decreases the probability of later maintenance work as well as making the construction process more economical and more sustainable. Glenium SKY and concrete formulations with an improved carbon balance are part of our Smart Dynamic ConstructionTM System that provides standard concrete with self-compacting properties.
