New workability enhancing admixture Sika ViscoFlow

In the area of concrete admixtures for ready-mixed and site-mixed concrete (Fig.), the Sika ViscoFlow product group opens up new possibilities for retention of the consistency of concrete and thus for its workability over periods of hours. Consistency and duration of workability of the concrete mixture are thereby positively affected along the entire dosing spectrum. This holds true for pure Portland cement as well as for a variety of cement mix types. Sika ViscoFlow superplasticizers are adapted to local conditions in every country and are thereby always based on proven Sika ViscoCrete Technology. Consistent and rigorous further development has generated extremely robust PCEs for daily use, which are provided globally under the Sika ViscoFlow brand name.
