PROTECT HWA (ST)

Stabiliser acc. to EN 934-2 for producing hydrophobic concrete

Item No. 2510

FIELDS OF APPLICATION

PROTECT HWA (ST) is a stabiliser with hydrophobic effects for mineral-based building materials and especially suited for producing manufactured concrete products and coloured concrete precast elements.

PROTECT HWA (ST) generates a hydrophobic concrete structure during the production process.

As a result the water penetration in hardened concrete is minimised. Thereby the occurrence of efflorescence is reduced and the frost resistance is significantly improved.

Consequently, PROTECT HWA (ST) makes a contribution to producing durable and sustainable concrete. PROTECT HWA (ST) stabilises concrete's texture, reduces segregation tendencies, improves concrete's compaction and attains a dense, homogeneous structure.

WORKING PRINCIPLE

PROTECT HWA (ST) 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.

PROTECT HWA (ST) maintains the water vapour transmission of concrete.

DOSAGE | APPLICATION QUANTITY

Recommended dosage range 1.0 – 4.0 mass-% of the cement content.
