Uses:
To minimize permeability and increase the waterproofing properties of concrete and cement sand mortars for critical applications like roof slabs and screeds, basements, external plastering, bathroom floors, water tanks,
sumps, drains etc.

Advantages:

• Liquid admixture: Instant and complete dispersion throughout the mix. Uniform waterproofing throughout concrete matrix.
• High efficiency: Dramatic reduction in permeability of concrete/ mortar
• Improved workability: Improves compaction of concrete and mortar, even where harsh sands or aggregates are used.
• Improved concrete quality: Minimizes porosity and honey combing. Produces dense homogenous concrete.
• Standards compliance: CX SUPERCONCRETE IWC+ conforms to IS: 2645-2003.

Description: CX SUPERCONCRETE IWC+ is a dark brown liquid based on lignosulphonates which mixes readily with water and therefore disperses evenly. CX SUPERCONCRETE IWC+ waterproofs by improving the quality of the concrete or mortar. It reduces the water demand for required workability and minimizes segregation and bleeding.

Thus it is more efficient compared to traditional power waterproofers as its use results in two fold improvement of concrete or mortar.

Properties:

• Chloride content: As per IS: 2645-2003
• Compatibility: Can be used with all types of cements, including Pozzolanic but not High Alumina Cement.
• Permeability to water: Less than 15% as compared to 50% max. Allowable under IS: 2645compared to
• control sample.
• Setting Time: No significant effect on setting time of concrete or mortar
• Compressive Strength: Maintains compressive strength equal to control concrete or mortar and can even
• improve on strength property if full advantage of water reduction potential is utilized.
• Workability: Improves workability at reduced water cement ratio

Application instructions:

• Mortar: CX SUPERCONCRETE IWC+ is ideal for use with all sand/cement mortars where it is required to reduce permeability to a minimum.
• Concrete: CX SUPERCONCRETE IWC+ is recommended for all general mass concrete work where, due to harsh aggregates, difficulty of compaction or mix control, the risk of porosity and permeability must be minimized. E.g. Basements, bund walls, tanks, balcony, floor and roof slabs.
• NB: The minimum dosage is 125ml and the maximum is 200ml per 50kgs of cement. If maximum dosage is used a minimum of 15% water should be reduced to ensure no loss in strength. Site trials shall be carried out to arrive at the optimum dosage. The required quantity of CX SUPERCONCRETE IWC+ is measured and stir into the first or second bucket of water. CX SUPERCONCRETE IWC+ water mixture shall be added to the concrete or mortar and mixed thoroughly. Mixing shall be continued and further water shall be added until the required workability is obtained. The total amount of water added per mix in the initial batches shall be maintained for the remaining batches.

 

Note: Mixes using CX SUPERCONCRETE IWC+ will require much less water than normal mixes for the same workability. Water reduction may be as much as 15% or more. If the moisture content of the sand or aggregate changes i.e., it becomes wetter or dryer, and then the amount of water used must be reduced or increased to give the original workability.

 

Estimating:

• Packaging: CX SUPERCONCRETE IWC+ is supplied in 125gm, 1, 5, 20 and 200 kg containers
• Storage: CX SUPERCONCRETE IWC+ has a minimum shelf life of 12 months, if kept in a dry store in unopened containers

Precautions:

 

• Health and Safety instructions: CX SUPERCONCRETE IWC+ is non-toxic.

CX Easy Mold EX is supplied as a pale amber liquid which turns white when diluted with water to produce a chemical release agent, combining the outstanding release properties of such materials with the economy of conventional oil. It reacts with the alkali in the concrete to form a thin water repellent skin on the
surface of the mold which enables easy stripping from the hardened concrete.

Uses:
For easy and stain free release of concrete molds and form-work of all types. Particularly where wooden form-work is used and De-molding or stripping times exceed 24 hours.

Properties:

• Dilution rate: 1 part CX Mold Release EX: 6 parts clear water (by volume)
• Form-work surfaces: May be used on wooden or metal surfaces. Particularly effective on resinous coated surfaces
• Non-staining: Can be used safely with white cement
• Specific Gravity: Typically 0.960 at 25°C

 

Application instructions:

• Mixing: First dilute CX Easy Mold EX. concentrate in the proportion of 1:6 with water, using a clean container and stirring thoroughly until evenly mixed. If the solution is not used the same day, it should be stirred again before use and may require very good stirring after 5 days
• New Moulds: No preparation is normally necessary Metal molds showing signs of rust, must be wire brushed or Treated with emery cloth and burnished clean before coating
• New timber: Plywood will give superior results
• Used molds: Must be thoroughly clean and free from old concrete, dirt, cement laitance, old mold oil and other contaminations. Use a strong detergent for removal of oil and grease; Recliner for cement and concrete deposits
• Application: Apply the CX Easy Mold EX. 1:6 water dilution to the face of the form-work by spray, brush or cloth. Only one coat should be applied (as thinly as possible except on very absorbent new timber where two coats may be necessary for the first application only) and allow to dry. If the form-work is not used for several days, a further coat may be applied. Only a very thin film of CX Easy Mold EX. should be applied. Excess could lead to surface dusting of the concrete. The best results are obtained by applying with a fine mist sprayer. Where a cloth is used, it should first be soaked in the release agent and then squeezed out well before applying. This ensures the thinnest possible film. CX Easy Mold EX. is not generally recommended where remolding is required within 24 hours, although excellent results may be obtained with shorter times
• Drying time: It is essential that the CX Easy Mold EX. is thoroughly dry before placing concrete. Otherwise, being an emulsion, its performance may be impaired. In condition of high humidity drying times will be much longer than in warm dry conditions
• Rainfall: It is necessary to protect freshly coated form-work from rain which may dilute the emulsion before it has
  dried. After drying the coating will withstand an occasional lightly shower but may be affected by heavy or continuous rain. In such cases, a further coat is advised once surfaces have dried out thoroughly 
• De-molding: De-molding can be carried out in the normal way and no special precautions are necessary. 
• After De-molding: Form-work surfaces must be thoroughly cleaned, but this is normally easy due to the excellent
  release action 
• Before re-use: The cleaned form-work surfaces must be Re-coated with CX Easy Mold EX. each time, in accordance with normal practice.

CX Easy Mold has specially formulated the blend of mineral oils and chemicals having release properties which are superior to those of conventional mold oil. The chemicals react with the alkali in the concrete to form a thin water repellent skin on the surface of the mold, thereby enabling easy striping from concrete and acting as a protection to steel and wooden formwork. CX Easy Mold is supplied as a pale straw colored liquid ready for direct application and use.

Uses:
To provide quick, clean and easy stripping of molds, and form-work and ensure high-quality fair-faced and stain-free concrete.

Advantages:

• Ensures easy release, good fair-faced concrete
• Can be used on all types of form-work
• Minimizes surface blemishes and staining
• Minimizes cleaning of shutters before re-use
• Reduces opportunity of damage to form-work, extending usable life

Properties:

• Specific gravity: 0.83 at 27 0 C
• Service temperature: Suitable for use with steam cured concrete.
• Form-work surfaces: Equally effective on wood or metal moulds and shutters. Particularly effective on GRP and other resinous coatings including CX Easy Mold coated wooden surfaces
• Non-staining: Does not stain concrete and can also be used safely with white cement
• Concrete surface quality: In addition to preventing adhesion of the cement paste to the mold or shutter face, allows air, which would otherwise be trapped, to escape from the face when the concrete is being poured and vibrated. Pockets of air, trapped on the shuttered faces of concrete, are a major cause of imperfections, necessitating remedial work. CX Easy Mold avoids time and money spent on this. The chemical reaction between CX Easy Mold and the cement in a concrete mix produces a strongly hydrophobic surface. This repels surplus water at the interface with the mold and by protecting the concrete from its effects, preserves uniformity of surface texture and color.
• Re-use of molds: Due to excellent release properties, little or no deposit of cement paste remains on the shutter surface. Minimum cleaning down and further coat of CX Easy Mold renders shutters ready for reuse
• Economic benefits: On account of the high rate of coverage, the applied cost of CX Easy Mold chemical mold release agent compares favorable with that of conventional mold oil. Having regard to the technical benefits additionally obtained, the overall economy of using CX Easy Mold can be significant.

 

Application instructions:

• Preparation of new molds: No preparation is necessary, but if extensive reuse of timber mold is envisaged, it is advisable to protect all new surfaces with CX Easy Mold. CX Easy Mold protects timber from alkali attack which can result in a very short usable life. For used molds, all traces of cement must be removed together with any surface deposit of previous oils.
• Coating: CX Easy Mold can be applied by brush, sponge or conventional mold oil-sprayer. If a mold oil-sprayer
  is used, care should be taken to ensure that the correct nozzle size is chosen. Stir the contents of the container
  thoroughly before use. Apply one coat of CX Easy Mold thinly and evenly over the entire surface. Only the thinnest coating necessary to achieve effective coverage should be applied. Excess application is uneconomical and may lead to surface dusting. Wipe or brush off any particles that may remain on the surface and apply one coat of CX Easy Mold as
  previously. If it is required to remove CX Easy Mold completely, a strong industrial detergent should be applied
  together with stiff brushing and then thoroughly rinsed with clean water.
