Sika® ViscoFlow® 44 is a workability enhancing admixture for concrete. It is a plasticiser / water reducer based on Sika ViscoFlow® technology which gives the concrete, long workability retention without causing a delayed setting effect. Sika® ViscoFlow® 44 can be used alone with weakly alkaline cements or in conjunction with another Sika water reducer as a workability regulator with medium or strong alkaline cements.
