Conbextra EP10 TDS - Parchem

Technical Data SheetConbextra EP10A highly fluid epoxy grout for dynamic/repetitive load applications gap widthbetween 0.25-10mmUSESConbextra EP10 is a low viscocity epoxy grout forsituations where heavy dynamic or mobile loads areencountered. It is ideal for grouting in small gaps betweena base plate and substrate which needs filling and thestructural load be uniformly distributed. Typicalapplications are reciprocating machinery, testingequipment, heavy crane and transporter rails, high speedturbines, centrifuges and drop forges.Also for use in conditions where chemical spillage may beencountered. Typical situations could be met in steelworks,refineries, electroplating works and chemical plants.Due to the low viscocity of Conbextra EP10 it can be usedto fill hairline cracks in concrete slabs from 0.25mm andupwards on horizontal surfaces using a gravity fedmethod.ADVANTAGES• High compressive, tensile and flexural strengths• Resistant to repetitive dynamic loads• Fast, convenient installation with early strength gain• Withstands a wide range of chemicals• Non-shrink and hence ensures complete surfacecontact and bond• Low creep characteristics under sustained loadingDESCRIPTIONConbextra EP10 for grouting gaps ranging from 0.25 mm- 10 mm. It is an all liquid system consisting of a base andhardener.TECHNICAL SUPPORTParchem offers a comprehensive range of high quality,high performance construction products. In addition,Parchem offers technical support and on-site service tospecifiers, end-users and contractors.DIMENSIONAL STABILITYFor the grout to effectively transfer load from the baseplate to the supporting structure it is essential that thegrout maintains intimate contact with the base plate.The area of contact between the grout and the base plateis measured as the ‘effective bearing area’ (EBA). In orderto maintain an even load distribution throughout the groutit is necessary to attain as high as possible EBA.The Conbextra EP10 has been designed so it achieves thebest possible EBA.CHEMICAL RESISTANCEConbextra EP10 is resistant to oil, grease, fats, mostchemicals, mild acids and alkalis, fresh and sea water.Consult Parchem Technical Services when exposure tosolvents or concentrated chemicals is anticipated.PROPERTIESThe following results are typical for the hardened grout at20°C.Test method for:Density (kg/m 3 ): 1060Compressive strength (MPa)1 day: 573 days: 667 days: 83Indirect Tensile strength @ 7 days(AS1012.10-2000)Modulus of Rupture @ 7 days(Flexural Strength)(AS 1012.11-2000)Typical resultEP1015 MPa @ 23 O C30 MPa @ 23 O CNote: Compressive strengths stated above were measuredusing cube samples.

Conbextra EP10POT LIFEAmbient temperature affects the time for which bulkmaterial will remain fluid.Typical values in minutes are:10°C 20°C 30°C 40°CPot Life 40 20 10 -EXOTHERMAll epoxy systems will develop a temperature rise onmixing. Its extent will be a function of the volume to surfaceratio, the ambient temperature, as well as the mass andthermal conductivity of the surrounding materials. ContactParchem for specific data on each product.SPECIFICATION CLAUSESSupplier specificationAll epoxy resin grouting where shown on the drawings,must be carried out using a suitable grade of Conbextra EPproduct manufactured by Parchem and used in accordancewith the manufacturer’s Technical Data Sheet.PERFORMANCE SPECIFICATIONAll epoxy resin grouting where shown on the drawingsmust be carried out with a factory packed product. Thehardened grout must have a compressive strength whichexceeds 80 MPa at 7 days, a tensile strength which exceeds15 MPa at 7 days and a flexural strength which exceeds 28MPa at 7 days.The storage handling and placement of the grout must bein strict accordance with the manufacturer’s instructions.INSTRUCTIONS FOR USEFOUNDATION SURFACEAll contact surfaces must be free from oil, grease, freestanding water or any loosely adherent material. Concretesurfaces should be cut back to a sound base. All dust mustbe removed and bolt holes or fixing pockets blown clean ofany dirt or debris.STEEL SURFACESAll steel surfaces should be shot blasted free of rust, paintand flaky mill scale.FORMWORKThe formwork should be constructed to be leakproof asConbextra EP10 is a free flowing grout. Loss of grout oncethe material is placed, but not hardened, will result inincomplete filling of the gap.For free flow grout conditions it is essential to provide ahydrostatic head of grout. To achieve this a feeding hoppersystem should be used.Forming materials should be coated with a release agentsuch as grease or wax material or a plastic coating. Thesecoatings act as a bond breaker so that a smooth groutsurface is achieved after form removal and the forms areprotected for reuse.MIXINGPour all the contents of the hardener pack into the basecontainer. Mix using a slow speed power mixer untilhomogeneous.For all products, mix using a slow speed power mixer fortwo minutes or until a uniform colour is achieved in thegrout.PLACINGThe mixed grout should be poured steadily from one sideonly 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 thetime taken to prepare the next batch.With the smaller 300ml kit size a nozzle is provided so thatwhen mixed can be squeezed or poured into small gaps orhairline cracks above 0.25mm.FLOW CHARACTERISTICSThe maximum distance of flow is governed by the gapthickness, the head of grout applied and the ambienttemperature.CLEANINGAll tools and equipment should be cleaned immediatelyafter use with Parchem Solvent. Spillages should beabsorbed with sand or sawdust and disposed in accordancewith local regulations.2
