    Shrinkage-reducing admixture reduces potential for concrete cracking

    How does MasterLife SRA 035 work?

    MasterLife SRA 035 shrinkage-reducing admixture was developed specifically to reduce drying shrinkage of concrete and mortar, and the potential for subsequent cracking.  It functions by reducing capillary tension of pore water, a primary cause of drying shrinkage.  MasterLife SRA 035 admixture will meet ASTM C 494/C 494M requirements for Type S, Specific Performance admixtures.

    Recommended uses:

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

    What are the features of MasterLife SRA 035?

    • Reduces the capillary tension of pore water in cementitious mixtures
    • Provides moderate to significant reductions in the drying shrinkage of cementitious mixtures
    • Reduces stresses induced from one-dimensional surface drying in concrete slabs, walls and other elements

    What are the benefits of MasterLife SRA 035?

    • Reduced microcracking and drying shrinkage cracking in concrete, mortar and paste
    • Minimized curling in concrete slabs
    • Improves aesthetics, watertightness and durability in concrete elements and structures
    • Minimizes prestress loss in prestressed concrete applications​
