KÖSTER BDM Powder (15kg)
Triple action crystallizing integral waterproofing for concrete
C 732
DESCRIPTION
KÖSTER BDM Powder is a crystallizing concrete integral waterproofing for the production of concrete with reduced water absorption.
A new type of KÖSTER technology with a triple effect:
- Enhances physical compaction
- Enhances crystallization processes
- Makes the inner capillary pore system hydrophobic
The combination of active ingredients contained in KÖSTER BDM
Powder improves the processing properties and thereby ensures a
physically denser concrete structure with a reduced pore diameter. The
chemical crystallization reactions of the cement are supported and
narrow or close capillary pores on contact with water. The catalytically
accelerated formation of nanocrystals reduces capillary water
absorption and activates the self-healing powers of microcracks. The
hydrophobic agent contained in KÖSTER BDM Powder is only actively
formed in the concrete mixture and is used exclusively for internal
hydrophobic pore treatment. An effect in terms of hydrophobing the
concrete surface is not to be expected.
Concrete integrally waterproofed with KÖSTER BDM Powder ensures:
- A reduced water demand when mixing
- A reduced capillary water absorption
- A crystallization and hydrophobicization of the capillary network
- A higher freeze-thaw resistance
- An increasd chemical resistance, thanks to reduced chloride ion uptake
- Longevity and durability of the concrete with increased functionality
AREAS OF
APPLICATION
KÖSTER BDM Powder is used as an additive in the production of
premixed or in-situ concrete. The type and amount of the addition
depends on the intended use.
KÖSTER BDM Powder is suitable for all concrete components with
permanent reduced water absorbency requirements.
For example:
- In collection and storage tanks
- Foundations
- Wall and floor panels
- Tunnel systems
- Precast concrete
- Many other fields of application
CONSUMPTION
0.75 - 1.5 % of the cement weight
