Notteproof CRS LQ
Description
CRS Liquid is a concrete additive that provides structural water impermeability by filling the pores and capillary cavities in the concrete with the chemicals it contains.
Usage Areas
- In water reservoirs, dams, treatment plants, pools, drinking water reservoirs,
- Foundation concrete,
- Retaining walls,
- In bridges, tunnels and canals,
- In concrete resistant to chemical and environmental effects,
- In mass concrete,
- In precast elements.
Characteristics
- Resistance to aggressive chemicals increases in concrete.
- It increases the strength of concrete against sulfuric acid and sulfate.
- It increases the freeze-thaw strength of concrete.
- It slows the corrosion of the reinforcement in the concrete.
- It has no corrosive effect. It won’t damage the reinforcement.
- It does not contain chlorine.
- Capillary water impermeability effect in concrete is permanent and structural.
- It is resistant to water pressure up to 14 bar.
- It is resistant to positive and negative water pressure.
- It fills the cracks and capillary cavities that may occur later in the concrete. (max. 400 microns)
- It can be used in drinking water tanks. It is not poisonous.
- It increases the early and final compressive strength of concrete.
Application Method
In the ready-mixed concrete plant, together with concrete mixing water:
- After 70% use of the mixture water, CRS LIQUID additive is added to the concrete.
- It is thoroughly mixed until a homogeneous mixture and the desired workability are obtained.
On the concrete in the trans-mixer in the ready-mixed concrete plant:
- When the trans-mixer is rotating on ready-mixed concrete in the trans-mixer, the concrete mixer truck may come out after the diluted CRS LIQUID additive is slowly added and mixed for at least 5-10 minutes.
In the wet ready-mixed concrete in the trans-mixer at the construction site:
- The reconstituted CRS LIQUID additive is slowly added to the ready-mixed concrete in the trans-mixer while the trans-mixer is rotating and the concrete is poured after mixing for at least 10-15 minutes.
In precast concrete plant:
- The CRS LIQUID additive is added to the concrete with the mixture water or as the final component.
DOSAGE
- Water : cement ratio Usage [Cement weight]
- <0.50 2%
-
0.50 3%
- In order for the CRS LIQUID additive to be effective, the water / cement ratio in the concrete must be at most 0.55.
WARNING
- Since the CRS LIQUID additive contains water and the additive addition will increase the total concrete water/cement ratio, the consistency class should be produced as a subclass in the concrete plant.
- Thus, when CRS LIQUID additive is added at the concrete casting site at the construction site, a desired upper consistency class will be obtained.
- There may be crusting/crystallization in the dosing apparatus due to the material structure. Therefore, the apparatus should be washed regularly and thoroughly.
- Precautions should be taken against crusting/crystallization that may occur in the mixer.
- After the CRS LIQUID additive is added, the wet ready-mixed concrete should be processed within ~45 minutes.
Adaptation
- CRS LIQUID can be used in conjunction with the following items:
- Portland cement, fly ash, slag.
- Test and consult our technical service before using with other concrete additives.
Consumption

- Stored in original packaging at +10°C /+30°C in dry, protected and ventilated environments, protected from sun, rain and frost, shelf life when stored is one year from the date of manufacture.
Safety Precautions
- During application and mixing, contact of the material with the skin and eyes should be prevented, and in case of contact, it should be washed immediately with water.
- In case of contact with eyes, they should be washed plenty of water.
- In case of water and medical assistance should be obtained.
- Gloves, protective clothing / masks / goggles should be used during use.
