RB-GE High strength epoxy grout

DESCRIPTION

RB-GE is a solvent free epoxy resin grout formulated to withstand static and dynamic loads in a wide variety of applications. The product is three component and easily mixed on site to a pourable consistency. RB-GE is suitable for an application thickness range of 40- 120 mm where high flow characteristics are required. Thickness may be reduced to 20mm when flow is not required.

APPLICATION FIELDS

  • Anchors and fixing bolts
  • Crane and transporter rails
  • New and old machine base plates
  • Structural filling of holes and cavities in concrete
  • Industrial equipment and machinery subject to static or dynamic forces
  • Equipment where chemical and acid spillage occurs
  • Pile cap waterproofing (at >20mm thickness)

FEATURES

  • Precision made, consistent results.
  • Shrinkage compensating.
  • Excellent adhesion to concrete.
  • Smooth, easily produced finish.
  • Low permeability
  • Excellent resistance to freeze / thaw action and carbonation
  • Reduces ingress of water borne salts, such as chlorides and atmospheric / chemical attack.
  • Subsequent paint coats can be applied with greater economy.

DIRECTION FOR USE

Surface preparation:

As with all epoxy resin applications the quality of surface preparation has a direct effect on the performance and durability of the system. Concrete surfaces should be sound, dimensionally stable, clean, and free from laitance, paint, oil, grease, mould release agent and residual curing compound. Metal surfaces or components to be bedded, should be free from any rust or scaling. Formwork, if used, should be wrapped in polythene to ensure a clean release.

Do not split packs or alter the ratio of resin components in any way. Mix with a slow speed drill and paddle. Add the contents of the reactor container to the base component in a suitable mixing vessel, ensuring complete transfer of both resin components.

Mix for one minute before slowly adding the aggregate and continue mixing until a flowing, pourable consistency is achieved. Do not over mix as that may entrain air.

Placing:

Place immediately after mixing, into the prepared area in such a manner that it has the shortest distance to flow. For longer pours a suitable head of pressure may be required. Ensure the area to be grouted is not completely sealed, and any displaced air can be expelled. Pour continuously from one end only.

Allow the grout to set prior to removal of formwork (normally after 6 hours). Where placement exceeds depths of 120mm, application should be carried out in layers. The second layer to be applied after 6 hours.

Do not apply RB-GE when the contact surfaces are less than 10°C. If the ambient temperature is less than 10°C then artificial heating may be used.

STORAGE

Store under cover, out of direct sunlight, and protect from extremes of temperature. In tropical climates the product must be stored in an air conditioned environment.

SAFETY

 

As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs (which can also be tainted with vapor until product is fully cured or dried). Treat splashes to skin and eyes immediately. If accidentally ingested, seek medical attention. Reseal containers after use. For specific storage and disposal instructions refer to the Material Safety Data Sheet.
