PROTECT HWR-65 (DM)

High-value hydrophobic admixture for the manufactured concrete product industry

Item No. 2565

FIELDS OF APPLICATION

PROTECT HWR-65 is a highly effective hydrophobic admixture suitable for the production of manufactured concrete products with reduced water absorption.

The use of PROTECT HWR-65 reduces the risks of erosion damages like freeze-thawing salt damages or visual deficiently signs like effloresces significantly.

Consequently, PROTECT HWR-65 advances concrete’s durability and long-term performance and can make a contribution to ecological sustainability therefore.

PROTECT HWR-65 generates a hydrophobic concrete structure. The product was especially developed for high value added manufactured concrete products in vibro-compaction and wet-cast production processes.

WORKING PRINCIPLE

PROTECT HWR-65 reacts with the cement matrix during the hydration process and generates a hydrophobic concrete texture thereby. This hydrophobic effect reduces the capillary suction and decreases concrete’s water absorption abilities. Having this properties the occurrence of efflorescence and frost damages are minimised.
