Typical applications include: „ Reciprocating machinery „ Heavy crane and transporter rails „ High speed turbines „ Centrifuges „ Drop forges „ Anchoring of steel bars „ Electroplating and chemical plants Description Conbextra EP65 Plus is a solvent-free rapid hardening, ultra high strength epoxy grout, based on the latest polymer technology. It is designed for use as a precision, heavy duty multi purpose grout for engineering applications. It is supplied as a two component system consisting of epoxy resin, combined with inert fillers and the hardener, to produce a high viscosity fluid grout. Advantages „ Very high compressive, tensile and flexural strengths „ Resistant to repetitive dynamic loads „ Fast, convenient installation with high early strength gain „ Withstands a wide range of chemicals „ Low creep characteristics under sustained loading Technical Support Parchem offers a comprehensive range of high quality, high performance construction products. In addition, Parchem offers technical support and on-site service to specifiers, end-users and contractors. Dimensional Stability For the grout to effectively transfer load from the base plate to the supporting structure it is essential that the grout maintains intimate contact with the base plate. The area of contact between the grout and the base plate is measured as the ‘effective bearing area’ (EBA). In order to maintain an even load distribution throughout the grout it is necessary to attain as high as possible EBA. Conbextra EP65 Plus has been designed so it achieves the best possible EBA. INDEX 140 Technical Data Sheet Chemical Resistance Conbextra EP65 Plus is resistant to oil, grease, fats, most chemicals, mild acids and alkalis, fresh and sea water. Consult Parchem Technical Services when exposure to solvents or concentrated chemicals is anticipated. Specification Clauses Performance Specification All epoxy resin grouting where shown on the drawings must be carried out with a factory packed product. The hardened grout must have a compressive strength which exceeds 125 MPa at 7 days, a tensile strength which exceeds 14 MPa at 7 days and a flexural strength which exceeds 28 MPa at 7 days. The storage handling and placement of the grout must be in strict accordance with the manufacturer’s instructions. Instructions for Use Foundation surface All contact surfaces must be free from oil, grease, free standing water or any loosely adherent material. Concrete surfaces should be cut back to a sound base. All dust must be removed and bolt holes or fixing pockets blown clean of any dirt or debris. Steel surfaces All steel surfaces should be shot blasted free of rust, paint and flaky mill scale. Formwork The formwork should be constructed to be leakproof as Conbextra EP65 Plus is a free flowing grout. Loss of grout once the material is placed, but not hardened, will result in incomplete filling of the gap. For free flow grout conditions it is essential to provide a hydrostatic head of grout. To achieve this a feeding hopper system should be used. Forming materials should be coated with a release agent such as grease or wax material or a plastic coating. These coatings act as a bond breaker so that a smooth grout surface is achieved after form removal and the forms are protected for reuse. Placing The mixed grout should be poured steadily from one side only to eliminate the entrapment of air. Continuous grout flow is essential. Sufficient grout must be available prior to starting. The time taken to pour a batch should be regulated to the time taken to prepare the next batch. Please refer to the Conbextra Epoxy Grouts Application Guide for further information.
