SikaControl® SRA 872 SA
(former MasterLife® SRA 872SA)
SHRINKAGE REDUCING ADMIXTURE
SikaControl® SRA 872 SA is a shrinkage-reducing admixture, developed specifically to reduce drying shrinkage of concrete and mortar as well as the potential for subsequent cracking.
SikaControl® SRA 872 SA admixture functions by reducing capillary tension of pore water, a primary cause of drying shrinkage.
Suitable for use in hot and tropical climate conditions.
SikaControl® SRA 872 SA increases cohesion within the concrete pore system. The contraction caused by water loss is reduced which results in significantly reduced drying shrinkage and therefore shrinkage cracking in correctly designed concrete mixes and structures.
With the application of SikaControl® SRA 872 SA the following advantages can be achieved:
With the application of SikaControl® SRA 872 SA the following advantages can be achieved:
- Reduced drying shrinkage cracking
- Reduced potential of slab curling
- Reduced permeability
- Increased concrete durability
- Significantly reduces drying shrinkage by as much as 80% at 28 days, and up to 50% at one year and beyond
