SikaControl® SRA 50

(former MLife 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.
