MasterLife SRA 872SA

Shrinkage reducing admixture 


MasterLife SRA 872SA shrinkage-reducing admixture was developed specifically to reduce drying shrinkage of concrete and mortar, and the potential for subsequent cracking. MasterLife SRA 872SA admixture functions by reducing capillary tension of pore water, a primary cause of drying shrinkage. 

Where is MasterLife SRA 872SA applied?

  • Ready-mixed or precast concrete structures requiring shrinkage reduction and long term durability
  • Wet mix shotcrete
  • Mortars and grouts 

What are the advantages of MasterLife SRA 872SA?

  • Reduces drying shrinkage cracking and microcracking thereby improving aesthetics, watertightness and durability
  • Reduction in drying shrinkage minimizes prestress loss
  • Minimizes curling
  • Significantly reduces drying shrinkage by as much as 80% at 28 days, and up to 50% at one year and beyond
  • Reduces stresses induced from onedimensional surface drying in concrete slabs and floors
  • Reduces carbonation
  • Can increase setting time from 1 to 2 hours, link to the dosage and temperature
