DURAHIT® SRA-200
Shrinkage-reducing admixture for durable concrete
Item No. 2569
FIELDS OF APPLICATION
DURAHIT® SRA-200 is a shrinkage-reducing admixture to produce durable concrete providing the following advantages:
> Reduces drying shrinkage
> Reduces curling, thereby compliance with joint spacing
> Achieves level floors
> Saves time and costly repairs
> Enhanced durability with longer lifecycle
The admixture is suitable for ready-mixed and pre-cast concrete and for all applications where the construction project requires controlled cracking.
DURAHIT® SRA-200 is especially designed for the following applications:
> Concrete screed
> Concrete floors
> Durable concrete in marine environments
> Watertight concrete
> Concrete with a high amount of cement paste and grout, e.g., self-compacting concrete or high-performance concrete
WORKING PRINCIPLE
DURAHIT® SRA-200 bases on carefully selected ingredients which have the capability of greatly reducing drying shrinkage. This allows the production of high-performance and durable concrete.
DOSAGE | APPLICATION QUANTITY
Recommended dosage range 0.5 – 1.5 mass-% of the cement content;
is equivalent to 5 – 15 ml per kg cement.
The use of shrinkage reducing admixtures may influence the compressive strength development.
