Definitions

  • the present invention relates to a method and a grout for closing cracks in concrete sleepers.
  • Icosit ® a 2-component epoxy resin binder, in the form of pourable mortar for bonding bolts and for pouring adhesive joints with a width of more than 1 cm to use. Resistant epoxy resin mortar is used for relining track pads, bridge bearings and machine foundations. Icosit ® is offered by Sika.
  • JP 2007 255039 discloses a method of remedying such thresholds wherein the gap is first potted with epoxy alone. Subsequently, a cement based on quartz sand is applied to the area above and around the gap.
  • DE 101 48 533 discloses a mixture of silica sand and epoxy resin for sealing rocks and structures. The mixture is pressed into the gaps and cavities. The Grain size of the solid is adapted to the dimension of the gap.
  • cracks in the concrete sleeper are cast with a casting agent which consists of a castable epoxy resin mortar.
  • the mortar is formed from a mixture of a Epoxidharzbindeschs with quartz sand.
  • the quartz sand has a grain size of 0.1 mm to 1 mm.
  • the grain size is 0.2 mm to 0.7 mm and more preferably 0.4 mm to 0.7 mm.
  • the sand used preferably has grains with diameters in the total specified range of grain sizes. However, it is also possible that a sand is selected whose grains have only diameters in a smaller than the specified range. Examples are ranges of 0.1 mm to 0.3 mm, 0.2 mm to 0.7 mm and 0.5 mm to 1 mm.
  • this pourable mortar is suitable for closing very small cracks in concrete sleepers. It has surprisingly been found that use of a finer grain size does not lead to a better result.
  • the mortar is surprisingly suitable for cracks whose width is not or slightly greater than the grain size of the quartz sand used. Thus, cracks of a width equal to or smaller than 1 mm, in particular of 0.3 mm, 0.5 mm and 1 mm can be cast and closed.
  • the epoxy resin binder and silica sand are used in a mixing ratio of 1: 1 weight percent.
  • the epoxy resin binder is a 2-component agent.
  • Icosit ® Sika has proven useful in particular Icosit ® Sika. Good results were achieved with Icosit ® KC 220/60 TX.
  • the crack to be closed is preferably dried before it is cast with the mixture.
  • a propane thawing device is suitable for drying.
  • the pourable mortar is applied with a spatula and thus into the crack, whereby it is passed along the crack.
  • the mixing ratio was 1: 1 by weight.
  • the penetration depth of the thus-mixed pourable mortar was always about 10 mm. There were no significant differences.
  • the potting compound is cured about 33 hours after processing.
  • the potted sleepers can be used immediately after completion of the renovation.
