Swelling concrete admixture acc. to EN 934-2 for producing expansive concrete

Item No. 0640

FIELDS OF APPLICATION

QUELLMITTEL (ST) is a powdery admixture for the production of expansive-cement concrete and mortar.

These construction materials are e.g. suitable for void fillings, for refilling small holes like cracks and for foundation underpinnings.

WORKING PRINCIPLE

QUELLMITTEL (ST) entrains micro pores in the cement lime. This process allows concrete to expand its volume purposefully. The swelling performance enables a precisely fitting into the surrounding hollow environment.

DOSAGE | APPLICATION QUANTITY

Recommended dosage range 0.2 – 2.0 mass-% of the cement content.
