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.
