Definitions

  • the cementitious and liquid constituents are now mixed together at ambient temperature in a hopper of a special sprayer in a ratio of three parts liquid constituent to one part cementitious constituent.
  • the mixture is stirred continually until it is used.
  • the mixture will set within about thirty minutes and therefore should be used within about twenty minutes of mixing.
  • the mixture is sprayed on to the rock surface to provide a layer of not less than 2 , 0 mm thick.
  • the spraying rate of the mixture is between two and three hundred litres per hour.
  • the cement constituent absorbs the water in the second constituent so that the surface layer will dry to a dry film even in conditions of 100% humidity so that it, the surface layer, will cure sufficiently to be self-supporting within fifteen minutes and to be able to give initial support for the rock within two to three hours.
  • the layer When fully cured, which will normally take about twenty eight days, the layer will have a uni-axial tensile strength of not less than 1,5 mega-pascals.
  • the layer is also adequately flexible having an elongation of between fifty and sixty per cent.

Abstract

L'invention concerne une matière de recouvrement de surface pouvant être appliquée par exemple sur des surfaces rocheuses et charbonneuses (par souci de commodité, le terme 'roche' renverra à la fois à la roche et au charbon dans cette description) de tunnels, chantiers et étais, ainsi qu'autour de plaques d'appui de boulons d'ancrage et permettant d'empêcher la fragmentation de la roche recouverte par cette matière. La matière comprend un mélange de constituant à base de ciment contenant un mélange de ciment à fort pouvoir d'absorption d'eau avec un deuxième constituant contenant une émulsion polymère à base d'eau. Le mélange de ciment à fort pouvoir d'absorption d'eau peut absorber au moins sa propre masse d'eau et parfois, cinq fois sa propre masse d'eau. La matière de recouvrement sèche rapidement dans les mines où règne une forte humidité et où il y a peu de ventilation.
