Information

Type:CN2000B
ZHONGHE 2000 high efficient anticorrosive and waterproof material (CCCW)
Cementitious Capillary Crystalline Waterproof Material with eka-molecule sieve structure

Description

The waterproof material CN2000B has eka-molecule sieve structure and permeation crystalline effect. The waterproof layer has breath, waterproofing and anticorrosion function.
CN2000B is cementitious, can firmly adhere to concrete. CN2000B contains some active substances. Under its catalysis, hydration is promoted and new insoluble crystalline is produced, which plugs up the passages of water and enhances compressive strength, bending strength, impervious pressure of the base structure.
Also when new tiny cracks occur, as long as there is water, the new formed crystalline can realize self-healing.
CN2000B effectively protects reinforced concrete and enhances its durability.

Applications

The product can be applied to the following fields: the energy engineering, traffic engineering, environmental engineering, industrial and civil engineering, defence engineering etc. For example:
•Hydroelectric facility, seaport project, coastal construction, wharf, underground gallery, underground plant, traffic tunnel, dam, lock, dock, reinforced concrete ship, wharf boat, etc.
•Airport terminal, road and bridge, squares, roofing, planted roof, pile head, foundation pile, foundation wall, baseboard, etc.
•Underground, tunnel, pedestrian passageway, culvert, basement, underground garage, underground store, etc.
•Municipal shaft, elevator shaft, cooling tower, tap water plant, toilet, sewage, sewage treatment plant, waste treatment plant, etc.
•Diversion canal, aquarium, swimming pool, water park, sea world, pool, etc.
•Warehousing, arsenal, civil air-defense construction, concrete deep shaft, underground headquarters, wind tunnel, etc.

Advantages

All technical performances achieve or exceed national and industrial standards.]
•High anti-permeability pressure
Have good impervious, high anti-permeability, and exceed both domestic and foreign similar products.
•Excellent antiseptic property
It could resist the corrosion of acid air, acid water, chloride, sulfate and glycol, etc. CN2000B material could be used for a long-term safety in the circumstance of pH value 3~12, CN2000C&D could be used for a long-term safety in the circumstance of pH value 2~12. It could restrain the alkali-aggregate reaction, efflorescence, carbonization.
•Good air permeability
The waterproof coating has the breath function of air permeability and watertight.
• Good stability
The waterproof coating is resistant to high or low temperature. It could keep its excellent properties in the circumstance of -40℃~160℃. It is Resistant to alternation of wetting and drying and cycle of freezing and thawing. Its appearance and properties aren’t changed through 200 times cycle of freezing and thawing. The crystalline structure which generated in coating and interface is stable. It is resistant to ultraviolet, radiation and anti-aging.
• Improve the strength of concrete
The permeation crystalline effect of coating makes the concrete denser. Its strength is higher.
• Have the capability of self-healing.
The active substance in material could prompt the self-healing of concrete microcracks which are less than 0.4mm when they come across the water.
• Green environmental protection
CN2000B is non-toxic and flavorless. It’s safe to human body and non-polluting to the environment. The content of HCHO, VCO, heavy metal and many other harmful substances are less than the instrument detection limit (The harmful substances haven’t been tested).
• Increase durability of concrete
Increase durability of concrete. Coating and concrete has the same long life.
• Simple construction
CN2000B could be applied in normal temperature and damp substrate. it is able to use the knife coating, spray costing installation, which is simple; setting is quickly, thus saving work and time; in underground well it is no need to prepare the ventilation condition for curing, it is suitable to various substrate conditions (new or old and complicate substrates).。
• Excellent economy efficiency
Compared with similar products at domestic and overseas, this material has high cost performance. The construction cycle is short (only one-sixth). It reduces the total cost greatly.

PACKAGING

Plastics pail: 25kg/pail. Woven bag: 25kg/bag

STORAGE

When stored in a dry place within -30~40℃, unopened, undamaged or original packing, shelf life is 2 years.

Direction for use
Recommended total dosage of material

In general: 1.5~2kg/m2 generally coat 2~3 coatings.
pecial case: decided by design request

Surface Preparation

• The substrate surface must be whole, solid and clean. Seeper, dust, oil stains and any dirt should be cleared and removed.
• Allow at least 7 days or more curing of the concrete of last pour before coating.
• If the substrate surface is smooth with rolling, It should be roughened.
• The loose honeycomb-type concretes, hollowings, joint seams and holes left over by pull rods and scaffolds must be eliminated beforehand and mended, in order to obtain better effects of applications.
• The substrate surface must be damp to wet saturation, but there should be no visible water on it.

Mixing

Materials’ ratio (weight):
• Trowel coating: CN 2000B: water=1:0.35±0.05
• Brush coating: CN 2000B: water=1:0.4±0.05
• Spray coating: CN 2000B: water=1:0.5±0.05
Mix CN2000B to water. Mix only as much material as can be used up within 20~30 minutes and stir mixture evenly. The stirring time generally is 5 minutes by machine. There should be no particles in it.

Applying

• Trowel coating:
Using a trowel or squeegee, apply the evenly mixed CN2000B to the working surface. First apply onto corners, sides and special places, and then apply onto leveling surfaces. Each coating should be consistent in the direction of application, while successive coatings should be perpendicular in direction. The thickness of joint place should be even. Allow preceding coating to finally set before applying the next coating. Commonly apply 2~3 coatings to reach total required thickness.
• Brush coating:
Except materials ratio (weight), other procedures are the same with trowel coating.
• Spray coating:
Except materials ratio and using special spray equipments, other procedures are the same with trowel coating.
 

Curing

After the final coating is finished and when it is just no longer sticky to the touch but its color doesn’t change into white yet, immediately cover the surface with a plastics film or intermittently sprinkle the surface with water keeping the surface damp and allow 24 hrs for curing or immediately coat a layer of CN2000C & CN2000D on the surface for naturally curing.
Solarization, rain or frost should be avoided during the curing.
For reservoir, water can be stored only after the coating cured for 7 days at least.

Technical Data

Aggregate state: powder
Color: off-white
Bulk density: approx. 1.30~1.35 g/cm3

Precaution

• The water quantity should be added according to the rules. Avoid adding too much water. It could influence the project quality.
• If the material begins initial set, it couldn’t be reused after add water.
• The ambient temperature for application is 5℃~35℃The best temperature for application is 20±10℃.
• In the open air application at rather high temperature, you could arrange the construction in morning or night. Avoid influencing the project quality from the coating dehydrate too quick, material hydrate, petrochemical not fully.
• This material isn’t decorative material. If vehicles and pedestrians pass over waterproof coating, protective covers are needed to be paved on it.
• The waterproof coating must be cured for 24 hrs before the next process to avoid destroying it.
•CN2000B is coating material. It can’t be used as an admixture to concrete or plasters.

Security Measures

CN2000B is cementitious. Avoid contact with skin and eyes. Should wear mask, goggles and gloves in mixing and stirring. In case of contact with eyes and skin, rinse immediately with plenty of water and seek medical advice if necessary.
Keep out of reach of children.
