FAIRCOAT E-GREEN

Environment friendly protective and Decorative coating for interiors and Exteriors

THE BASIS OF ECO FRIENDLY PAINTS
Natural ingredients are at the heart of the unique qualities of FAIRCOAT E-GREEN. The binder is liquid silicate whose structural form and hardness is perfectly compatible with its inorganic colorants and the inorganic concrete and masonry structures it is applied to.

PENETRATION PROPERTY
The principle strength of silicate paints is their penetration within the substrate. This results in a solid mineral and insoluble compound of paint and substrate (concrete, natural stone, marble, etc). The cross-section through the render shows this penetration, which is also known as silification. This chemical bond locks the paints into the subsurface as opposed to organic coatings that sit on the surface.

FACTORS AFFECTING PENETRATION DEPTH
While penetration depth may not be critical for many architectural applications, greater penetration will have a significant effect on strength and durability of applications on cement based substrates, porous stone and traffic bearing surfaces. Penetration depth is influenced by the substrate’s pore structure and permeability, moisture content and surface preparation.

When FAIRCOAT E-GREEN is applied to suitable substrates, it penetrates and reacts to form a hard, insoluble silicate. It can also increase substrate hardness, particularly in cementitious materials. When applied to materials containing Portland cement, the silicate reacts with incompletely hydrated cement particles, converting unreacted calcium hydroxide (CaOH2 or hydrated lime) to harder calcium silicate hydrates.

WATER VAPOUR PERMEABILITY
The high water vapour permeability of silicate paints is due to their crystalline nature which ensures that humidity present in the masonry can freely pass from the substrate. Thus water cannot build up between the paint and the substrate – which normally leads to paint cracking/ blistering and being pushed off the surface. Instead, the substrate remains dry and the breathability of the building is maintained.

INCOMBUSTIBILITY
FAIRCOAT E-GREEN do not burn, unlike emulsion and other organic based paints. In the event of a fire breaking out, damage to the substrate is reduced and the paint does not give off any toxic fumes.

NO FUNGUS, ALGAE OR MOLD
The pure inorganic inert composition and high pH of silicate paints prevents any fungi, algae or mold growth, thus assuring a hygenic and clean paint layer. The absence of surface condensation due to the coatings high water vapor permeability, promotes a clean, healthy environment. Traditional organic paints provide smooth film coatings that do not breathe, attract moisture and fungi, algae and mold spores. Toxic mold growth is the number one health problem in building structures today. FAIRCOAT E-GREEN can improve the health of the building environment.

REGULATION OF TEMPERATURE
Silicate paints have a micro-crystalline structure, which reflects lightand heat. In hot climates this reflective property reduces the thermalstress on the structure and reduces the amount of cracking the substratewould normally undergo.

LIGHT FASTNESS
Neither harsh climates nor high UV radiation can alter the color of a FAIRCOAT E-GREEN Redecoration in the same color shade is possible after many years. Traditional organic paint coatings are subject to UV deterioration from day one, breaking down the paint film which changes the color and causes the coating to fail. Silicate paints have an extremely long life providing important economies over the long term.

ENVIRONMENTALLY SAFE
This water based Silicate paints are harmless to the environment, consisting of natural mineral compounds including quartz, inorganic mineral colorants and liquid silicate used as a binder. Silicate paints represent a technology which has no detrimental effects on the environment in terms of manufacturing as well as in terms of application. Under fire conditions no toxic fumes evolve as the FAIRCOAT E-GREEN does not ignite.

Thus FAIRCOAT E-GREEN is Breathable, Moisture Resistant, Does not contribute to growth of mold, algae or mildew, Durable and UV Resistant; does not yellow, fade or peel.

FAIRBOND CS

SEGMENTAL CONCRETE BRIDGE BONDING

FAIRMATE supplied the concrete admixtures and other products for the precast and insitu concrete works on this structure, and now we develop a high strength epoxy resin adhesive system, to bond the joints between the precast concrete segments.

The Successful combination of new pre-stressing systems with new assembly equipment led to the development of the precast segmental construction method for bridges. The most important first developments were probably in 1940s, and it is now used by many of engineers, contractors, equipment producers and manufacturers around the world. It has become established and used successfully on numerous large projects, including many of the world’s most important recent bridge structures.

FAIRBOND CS PRODUCTS – SEGMENTAL BRIDGE BONDING

FAIRBOND CS (S) & FAIRBOND CS (W) has been used extensively for a segmental bridge bonding construction applications, the need became clear for a specific range of segmental bridge adhesive which could meet the different and increasingly precise requirements of bridge designs and at the different working temperatures which occur during their construction periods. These included application in daytime temperatures of up to 45°C, curing during very low and cold night time temperatures, plus the rapid erection cycles demanded for the precast segments.

The FAIRBOND CS (S) & FAIRBOND CS (W) were the result – a range of adhesives, optimized for the specific technical requirements, suitable for use on the most challenging bridge projects. This is based on a reactive hardening epoxy binder system, with optimized filler granulometries, so that the products support the continuously optimized production process of segmental bridge construction.

The Fairbond CS (S) & Fairbond CS (W) (segmental bridge adhesive) range, which fully complies with FIP and AASTHO standards, but also to be able to meet the specific requirements of each construction site.

The application and characteristics of segmental bridge bonding products must be carefully matched so that the adhesive can meet the following requirements:

• To bond the surfaces so that compressive and shear forces also the tensile forces can be safely convey from to every bridge segment.
• To lubricate the joint faces between the segments to make them easier to finally position together during their installation.
• To seal the joints between the segments against future ingress of water and de-icing salts etc,i.e. to protect the prestressing cables against corrosion.

THE PERFORMANCE REQUIREMENTS

In order to meet all these requirements under the different site application conditions, including variable temperatures/ moisture contents/ mixing and application methods etc., the epoxy adhesive must have carefully selected precisely defined characteristics and test methods to confirm these.

The table below contains the main criteria covered by “International Federation of Prestressing” FIP (now developed as fib “Federation international de beton) and AASTHO (American Association Of State Highway and Transportation Officials), which have also shown the FAIRBOND CS products specification.

EPOXY JOINTING ADHESIVE

Purposes of Epoxy

The purposes of using an epoxy resin in the joint between the segments are:

• To maintain the structural integrity of the joint and maintain a monolithic concrete segment
• To completely fill any minor surface imperfections and irregularities between the match cast surfaces
• To provide a water and grout tight seal, preventing chloride intrusion
• To act as a lubricant when erecting the segment
• To ensure tight fit between the segments so that the compressive and shear stresses are transmitted directly across the joint

TYPES AND APPLICATION OF EPOXY

Epoxy comes in two part compounds consisting of a resin and hardener. When mixed together, they begin curing which can take anywhere from a few minute to a few hours, depending on the formulation, the site and storage temperature and the mass of the epoxy, The cure time will be shorter when epoxies are mixed in higher temperature conditions and in larger masses.

Segmental bridge epoxies are specially formulated as either normal or slow setting resins. For Segment by segment erection, the normal set epoxies are used and for span by span erection, the slow set epoxies are used. It is important to use the correct pot life and correct temperature range to ensure good working time and proper strength gain of the epoxy.

Surface preparation:

Concrete should be mechanically sound and free form contamination such free water, mould oil, grease, laitance or dust. A dry grit blasting on the surface is recommended for optimum adhesion. Sections to be checked for good alignment. A ‘dry run’ before the first application of the adhesive is recommended to ensure correct timing.

Mixing:

The contents of hardener should be added in to the base and mixed for 2-3 minutes with a paddle attached slow speed heavy duty drill. It should be ensured that the sides and base of the can is thoroughly scrapped down. A uniform grey colour should be obtained after homogenous mixing.

Application:

The mixed adhesive should be applied at required thickness to both laying surfaces with a serrate trowel or other suitable spreader. The joint should be closed immediately. If this is not achieved the surface of the adhesive should be slightly scratched immediately prior to closing the joint to be exposed fresh adhesive. The joint must be closed within the open time of the adhesive. On site monitoring of the operation using lapped asbestos cement panels is recommended.

When the segments are brought together and stressed, excess epoxy is squeezed out. For joints over traffic or water, procedures must be implemented to avoid dropping below. Once the segments has been joined and stressed, all excess epoxy should be cleaned. If leaving it to harden will make it more difficult to remove later on.

Cleaning:
Tools and equipment should be using SAFECORE TOOL CLEANER immediate after use.

SHELF LIFE AND STORAGE
FAIRBOND CS (W) & FAIRBOND CS (S) will have a shelf life of 12 months in un-opened containers when kept in dry conditions at a temperature 5 0c to 30 0c. Storage at higher temperature or high humidity may reduce the shelf life.

HEALTH AND SAFETY
FAIRBOND CS (W) & FAIRBOND CS (S) is non-flammable. However, it should not come in contact with skin and eyes. If accidental skin contact occurs, remove immediately by washing with soap and water – Do not use solvent. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Avoid inhalation of vapors and ensure adequate ventilation.

FAIRCRETE RMW

INTEGRAL WATERPROOFING ADDITIVE FOR CONCRETE AND PLASTER

Water leakage and seepage is the enemy of all structures. It is important to build correctly with due attention to water proofing of basements, exterior walls, roofs and building watertight pipelines. Large numbers of structures lack proper implementation and thereby have less life. If water enters and starts damaging any part of the structure, early repair action must be taken. For excessive damaged structure restoration may be possible by use of repair chemicals after ensuring structural safety.
We realize there is a need to provide building professionals with suitable specialized information to enable them to ensure higher life of all structures. FAIRMATE CHEMICALS PVT. LTD. is a step in that direction. In the developed countries, use of Construction Chemicals is quite extensive. India has to catch up with high growth rates in this field.
Leakage is a common problem in any home or structure, caused either by the age of the structure, or improper
construction and design methods. Some of the most common reasons for water leakage in structures are elaborated below:

1.Construction Practices

• Untrained man power
• Improper preparation of mortar and concrete mixes
• Use of excess water for to make mixes easily workable, which results in porous concrete, inviting leakage.
• Bleeding & segregation in concrete resulting in honey combing/voids
• Inappropriate compaction/vibration of concrete
• Inadequate curing in early and later stages
• Negligence in site supervision.

2.Inappropriate Material Selection

Enough care is not taken in specifying the correct construction materials such as :

• Right quality & grade of cement depending on service requirements
• Good quality crushed aggregates of various sizes depending on mix proportion
• Sand free from silt and other chemicals
• Potable water, i.e. water should not contain any chlorides, etc.
• Other chemical and mineral additives that can increase the durability of construction

3.Aggressive Climatic Conditions

Environment plays an important role in determining the durability of any structure. More aggressive the climate, more stringent is the precautions to be taken. Structures which are exposed to marine regions or situated in polluting industrial belts, are more prone to chemical attack.

4.Mechanical Damage

Concrete structures are not often used only for the purpose they have been designed, but subjected to forces such as excessive loading, impact, abrasion and other mechanical damages. As a result, structural cracks develop in slabs. These too contribute to the problem.

5.Inadequate Maintenance

Problems like cracks, dampness, etc. are neglected in the initial stages and timely corrective measures are not undertaken, ultimately leading to deterioration of the structure. It is advisable to undertake preventive maintenance and carry out timely repairs through a competent contractor, the correct specification for materials and methods, depending upon the problem.

Diagnosing the root cause of the problem is vital. Only then a suitable solution can be arrived.
The treatment will then be cost effective from the long term point of view. Repair or maintenance must be done

systematically as under:
Visual inspection

Non destructive testing as advised by a consultant or an expert, if required Once the diagnosis is done, a proper scheme can be made to undertake repair and rehabilitation work using suitable materials aided by construction chemicals.

Benefits
• Ensures perfect watertight structure
• Reduces water penetration
• Reduces mortar dropping , when used in plaster.
• Reduces CO2 attack.
• Contains no flammable ingredients and is non corrosive.
• Very low cost
• Increase plasticity of concrete, thus it flows easily without increase in water and better compaction is achieved.
• Does not affecting the setting time of the concrete and mortar.
• Becomes an integral part of the concrete.
• Reduces efflorescence.

WHERE TO USE:
Permanent reinstatement of opening in carriageways, footways, cycles paths, private drives, reinstatement of pot holes. Remedial repairs around manholes.

LYING: Minimum thickness 15 mm.

CURING: No curing is required.

COVERAGE: The depth & width of pothole, crack, utility cut etc. will greatly influence the coverage rate achieved.

CLEAN UP: All tools should be cleaned immediately after use with a solvent base cleaner such as paint thinner or mineral spirit.

TESTING: FIVE CATEGORIES WERE DEFINED AND RATED AS FOLLOWS.

1. Bleeding: Is the flushing of the asphalt binder to the surface of the patch. IT caused by a combination of traffic loads, insufficient voids in the mix, or too much binder in the mix. Bleeding may cause poor skid resistance. – The use of open (gap) gradation and lower binder content should keep bleeding to a minimum.

2. Dishing: Is the further compaction of the patch under traffic loads. It is the result of material instability and inadequate compaction during the placement of the material. Compatibility is related to workability. Mixes with poor workability is difficult to compact. To determine the amount of dishing, a 1-m metal bar was placed across the patch parallel with the direction of travel. The amount of dishing was measured with a ruler accurate to 1.5 mm in the centre of each quadrant. The ratings were determined from the depth measurements.

3. Debonding: Occurs when the patch material loss its adhesion to the pavement at the bottom and/or sides of the pothole. When debonding occurs, the patch material can be pulled out of the hole by traffic, so the patch fails. It can be determined by disintegration i.e. the cracking cause at the edge of the patch for each quadrant. Missing patch was evaluated as a large scale loss of material. In some cases, these appeared to the cohesion failures rather than adhesion failures as all of the remaining particles were fully coated.

4. Raveling: is the loss of aggregate form the surface of the patch. Raveling is cause by stripping, poor cohesion, excessive fine aggregates and poor aggregates interlock of the patch material.

5. Pushing and shoving: is the vertical or horizontal movement of the patch material in the pothole.

The behavior of the ROADCRETE MACADAM in the above testing is very good.

WORKABILITY TEST:

The workability of the mixture was examined using the pennsylania transportation institute/ strategic highway research program (PTI / SHRP). For the PTI test, the sample is loosely placed in a 102 mm cubical box with a 10 mm hole centered on one side. A soil penetrometer with a round nose adapter 10 mm in diameter is pressed through the hole into the material. The value from the penetrometer is recorded as the workability reading.

The workability of the material was evaluated after they had been stored for 6 months as a measure of their storage ability.

The ROADCRETE MACADAM results of the workability surveys are good.
The evaluated at 7 and 14 days and 1, 3, 8, 9 and 12 months after placement.

PACKING AND COVERAGE:

ROADCRETE MACADAM is supplied 25 kg packs A 25 kg pack yields 12.5 ltr of mortars sufficient for 0.75m2 @ 25 mm thick.

On old or porous surfaces, ensure that the substrate is sound and free from any loose particles. Apply FAIRCRETE SBL, apply FAIRCOAT SCREED on the primed surface.

Application :
Stir the material in the container thoroughly and spread evenly with trowel. Avoid application during rainy weather. The surface texture and porosity must be taken into account while estimating quantities.

Cleaning :
Tools should be cleaned immediately after use with water.
