DURAHIT® Crystal Ad 2000 (DM)

Hydrophobic crystalline water resisting admixture acc. to DIN EN 934-2 in powder form

Item No. 3651

FIELDS OF APPLICATION

DURAHIT® Crystal Ad 2000 (DM) is a hydrophobic and crystalline admixture especially designed for providing concrete with an integral, permanent waterproofing system.
The special technology reduces the capillary diameter and provides a self-sealing effect to the concrete structure. This effect enables concrete to self-heal shrinkage cracks up to 0.4 mm.

DURAHIT® Crystal Ad 2000 (DM) is therefore suitable for concrete projects with advanced requirements in durability and quality and where optimum waterproofing is required. Typical applications are:
  • Marine structures like harbours and docks
  • Dams, water reservoirs, water containment structures and swimming pools
  • Tunnel- and underground constructions
  • Waste treatment facilities
  • Basements and foundations
  • Precast concrete
  • Potable water structures


DURAHIT® Crystal Ad 2000 (DM) achieves a very effective protection mechanism which provides the following benefits to concrete:
  • Significantly decreased water penetration
  • Subsequent crack minimising
  • Seals existing and future cracks up to 0.4 mm
  • Resits high hydrostatic water pressure from either positive or negative side of the building component
  • Enhances resistance against chemicals and aggressive media
  • Decreased risk of steel corrosion
  • Increases concretes durability and rises its longterm performance
  • May contribute to lower maintenance costs and less replacements


Since DURAHIT® Crystal Ad 2000 (DM) advances concrete’s durability, the waterproofing admixture can make a contribution to ecological sustainability.

WORKING PRINCIPLE

DURAHIT® Crystal Ad 2000 (DM) consists of Portland cement, very fine treated silica sand and various active, proprietary chemicals that react with the free lime and moisture in the concrete mix in order to generate permanent and durable crystalline system.

This crystal formation becomes an integral part of the cement matrix providing waterproofing properties and optimum protection against water ingress.

DURAHIT® Crystal Ad 2000 (DM) still allow the passage of vapour diffusion through the concrete structure.

DOSAGE | APPLICATION QUANTITY

The dosage of DURAHIT® Crystal Ad 2000 (DM) is 2.50% of the total tempering water of the concrete including the moisture of aggregates and sand.

The total dosage range is 0.50 – 2.00% of the cement content by weight.
