In the presence of water, the natural components of cement (silicate, aluminates, and dissociated calcium oxide) trigger a chemical reaction under the catalyst of the proprietary active substances of CN2000B®, producing insoluble crystalline along the voids, blocking the passage of water and other harmful corrosives. CN2000® creates an impenetrable barrier to water and other liquids while still allowing the concrete to breathe. The active proprietary materials in CN2000B® will remain dormant within the concrete until moisture attempts to re-enter. The moisture will once again activate the proprietary materials to produce more crystals, blocking the passage of water. The active materials will continue to penetrate and protect the concrete for its natural lifespan. CN2000® cures in 24 hours allowing for the next operation to begin.
In the process of developing CN2000®, a study of molecular physics, the intermolecular force and the movement rule of molecules, introduced the concept of the “eka-molecular sieve” to the capillary crystalline process. The main body of the waterproof material has been designed to have the structure of the eka-molecular sieve. The waterproof layer has a high impervious strength and still has the ability to breath. Thus the desired effect of ventilation and waterproofing is achieved.
The activating substance of CN2000® is made from unsaturated polar molecules and is an ultra-fine (nm) powder. It will attach on the surface of the cement stones by the action of another important special auxiliary material, a sort of eka-molecular sieve. The latter has many pores with a certain uniform size with a very high specific surface area. Its characteristics are:
- It can absorb certain molecules optionally according to the size and form of molecules; and
- For polar and unsaturated molecules, the stronger the polarity and unsaturated degree is, the stronger its adsorption opting ability is.
CN2000® contains cement and quartz sand which acts as a dispersing agent enabling uniform distribution among them.
After the activating substance at the molecular level is absorbed on the surface of the eka-molecular sieve and all its fine holes, it spontaneously separates into the atomic level state. At this point, the activating substance exists in the small cages of the eka- molecular sieve in a positive or negative ion or their “inclusion body” form, thus the activating substance is activated creating ionization. Enrichment and ionization of the activating substance with the help of the eka-molecular sieve creates the condition for its diffusion and migration throughout the concrete substrate.
