1. PRODUCTS SPECIFICATIONS

1.1 Product Description:

CHEM-CRETE PAVIX CCC100 is a unique water-based chemical product that is intended to provide a permanent treatment and ultimate protection of large-scale concrete substrates against temperature and moisture associated problems such as thermal cracking, damage caused by repeated freeze and thaw cycles, chloride ion penetration, as well as alkali silica reactions.

CHEM-CRETE PAVIX CCC100 is the only product of its kind that combines the repelling function along with a unique hygroscopic and hydrophilic internal moisture blocking mechanism. Its low viscosity allows it to penetrate easily and deeply into concrete substrates where it reacts and results in an outstanding performance.

CHEM-CRETE PAVIX CCC100 promises to keep treated concrete reasonably dry, thus eliminating most water and moisture associated problems. It will also seal cracks up to 1/16th of an inch. Therefore, it will prolong the life span of the structure and dramatically reduce maintenance cost.

4. PACKAGING

CHEM-CRETE PAVIX CCC100 is available in 5 Gal Pails and 55 Gallon Drums.

5. COVERAGE

It is recommended to apply CHEM-CRETE PAVIX CCC100 at a rate of 150 to 200 ft 2 /gallon

(3.6 to 4.8 m 2 /l).

6. QUALITY ASSURANCE

CHEM-CRETE PAVIX CCC100 for the treatment and protection of concrete substrate works on the mechanism of forming different types of crystal. The progressive growth of these crystals minimizes the diffusion and penetration of water, chloride ion, and all other concrete problems associated with the presence of water.

CHEM-CRETE PAVIX CCC100 is different from any other water proofing sealer in the following issues:

1. It is a non-film forming product. Unlike other sealers, the application of CHEM-CRETE

PAVIX CCC100 will not reduce the friction resistance (which important in highways, airplane runways, and taxiways) of the concrete since it penetrates through the pores and the capillaries of the concrete.

2. It prevents the moisture and chloride ion diffusion in all directions while sealers prevent it only from the surface ignoring the other unsealed surfaces.

3. It penetrates through the pores while the crystal grows continuously with time until complete protection, while sealers deteriorate with time.

The crystal, as shown in the figure, is of a microscopic size, which cannot be seen by eye.

However, a permeability test for sample treated with CHEM-CRETE PAVIX CCC100 will show a major reduction in water permeability. Long term testing by independent lab test is available to show such reduction. Other independent lab tests showed that using CHEM-CRETE PAVIX

CCC100 reduces the chloride ion diffusion by half. It also reduces scaling by at least 60%. All of that would double the life of the concrete.

7. GENERAL SURFACE PREPARATION.

Surface Surface Surface

Concrete surfaces must be clean and sound prior to applying the product. Cleaning will open the surface pores and capillaries in order to enhance the penetration process.

Compressed air can be used to remove dust and loose particles from the surface. Flushing the area to be treated with water can improve the cleaning process. However for heavily contaminated areas, special concrete cleaning agents ca be used to remove dirt especially those contaminated with oil.

The surface must be allowed to dry prior to applying Chem- Crete PAVIX CCC100. CHEM-

CRETE PAVIX CCC100 can be applied to concrete surfaces in one single coat only by means of spraying, sweeping or brushing. For large scale applications, such as airport runways, it is recommended that CHEM-CRETE PAVIX CCC100 must be applied using a heavy duty commercial sprayer similar to the one shown below. The figures below show the major parts of a typical commercial sprayer for the use in the application of the CHEM-CRETE PAVIX

CCC100. The sprayer contains surface preparation equipment in the form of high pressure hot water sprayer.

8. TREATMENT OF MOISTURE ASSOCIATED PROBLEMS IN CONCRETE

8.1 Concrete Substrate

CHEM-CRETE PAVIX CCC100 is mainly used to protect the concrete substrate, the high way substrate or airports runways, taxiways. The following figure shows the major water associated problems in concrete substrate. CHEM-CRETE PAVIX CCC100 eliminates these problems by forming crystals in the body of the concrete substrate in all directions. The product with the low viscosity penetrates the concrete substrate from all directions.

Figure 6: Typical moisture associated problems in concrete substrate.

By the treatment with CHEM-CRETE PAVIX CCC100, c racks smaller than 1/16” will be protected and repaired. The mechanism of this treatment is shown below.

Protection zone Treated crack

PAVIX CCC100.

8.2 Construction Joints

The construction joints, ether in concrete highways or airport runways or taxiways, are subjected to high stresses. These stresses in the presence of moisture are developed into crack formation and thus deterioration of the concrete around the construction joints. Figure 8 and 9 presents schematic diagram and a picture for deteriorated concrete at a construction joint, respectively.
