Concrete / mortars

Increasingly demanding performance and environmental standards have created new challenges for construction formulators. Our expertise in wetting and foam control puts us in a good position to help formulators build better performance in concrete admixtures and dry-mix mortar systems. For example, the demand for higher durability concrete has resulted in increasing use of polycarboxylate superplasticizers (powerful water reducers that lead to entrained air). Fortunately, Evonik offers stable and high-performance de-airentrainers that allow concrete admixture formulators to successfully formulate with all types of polycarboxylate superplasticizers. Additionally, Evonik offers highly efficient powdered additives that enhance cementitious dry-mix mortar applications performance at very low use levels. These products provide various benefits including faster production and pumping speed, reduced shrinkage, improved adhesion, dust-reduction, smooth and defect-free surface appearance in flooring compounds as well as improved flow and leveling. Their compatibility with other additives also allows wide formulation latitude.
