SPECCO SRA-100 is a specialty liquid admixture specifically formulated to reduce drying shrinkage in concrete mix designs. Drying shrinkage of concrete is known to be associated with the surface tension of the mix water and the related capillarity they form when curing. SRA-100 works by lowering the surface tension of the water and reducing the corresponding strain forces pulling on the water during drying. Typical uses include concrete structures or environments that are susceptible to high degrees of drying shrinkage such as bridge decks, parking garages, silos, floors, walls, piers, water tanks, pipe and related precast .
- Reduces ultimate shrinkage values by up to 50% depending on cement type used.
- Minimizes related cracking from chemical or drying shrinkage.
- Decreases maintenance costs of the structure.
- Increases long term durability.
