SikaControl® SRA 50
(former MasterLife® SRA 50)
Expanding plasticising admixture for cementitious grout and concrete
SikaControl® SRA 50 is an expansion system which compensates for plastic shrinkage and settlement in cementitious grouts and concrete.
Supplied in powder form, SikaControl® SRA 50 produces controlled expansion and maintains high water retention. It contains a water-reducing agent which increases the workability of the mix with a reduced water content. Full expansion is achieved before initial setting occurs resulting in a high degree of interfacial contact.
Suitable for use in hot and tropical climatic conditions.
- Improves the free flowing properties of the grout or concrete at low water/cement ratios.
- Increases the volume of the grout or concrete which in turn offsets shrinkage and settlement.
