(former MRheobuild 858)
High range water-reducing and slump retaining concrete admixture
Sikament® RB 858 is a highly effective dual action liquid superplasticiser that imparts excellent slump retention for prolonged periods.
Suitable for use in hot and tropical climatic conditions.
Sikament® RB 858 provides the following properties:
As a Superplasticiser:
▪ Workability is greatly improved
▪ Concrete is placed easily
▪ Especially suitable for slender components with densely packed reinforcement
▪ Concrete requires less vibrating
▪ Improved cohesion of the concrete mix significantly reduces the risk of segregation and allows greater time for placement
As a Water Reducer:
▪ Impressive water reduction capability
▪ Final strength improvement
