PROTECT HWR-90 (DM)

Mass hydrophobization for high-quality manufactured concrete products

Item No. 2590/D

FIELDS OF APPLICATION

PROTECT HWR-90 is a highly efficient integral hydrophobic admixture suitable for the production of high quality manufactured concrete products with reduced water absorption, e.g. paving stones, paving flags and manufactured concrete products that are surface coated. The product is applicable in face or core concrete as well as in wetcast production.

WORKING PRINCIPLE

PROTECT HWR-90 reacts with the cement matrix during the hydration process and thereby generates a hydrophobic concrete texture. This hydrophobic effect reduces the capillary suction and decreases concrete’s water absorption abilities considerably. Due to these properties the occurrence of efflorescence
is minimised and the durability of concrete is increased.

DOSAGE | APPLICATION QUANTITY

Recommended dosage range 0.3 – 1.0 mass.-% of cement content; is equivalent to 4 - 11 ml per kg cement.
