MasterLife SRA 872SA
Shrinkage reducing admixture
Description
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,
