Title (EN) SELF-LEVELLING CONCRETE AND METHOD FOR MAKING A STRUCTURAL PART
(FR) BETON AUTONIVELANT ET PROCEDE DE FABRICATION D'UNE PIECE DE CONSTRUCTION
Abstract:
(EN) The invention concerns a self-levelling concrete and a method for making a structural part from said concrete. The concrete which comprises aggregate and solid particles with size grading not more than 12 mm, comprises a superplasticizer which is a compound containing at least an amino-(dialkylene phosphonic) group and at least a polyalkylated chain, or one of its salts. The method is implemented by advantageously pumping the concrete using one or several immersion tubes (12) with their injecting end (15) at a lower level than the framework.
(FR) La présente invention concerne un béton autonivelant et un procédé de fabrication d'une pièce de construction à partir d'un tel béton. Le béton, qui comprend des granulats et particules solides de granulométrie inférieure ou égale à 12 mm, comprend un superplastifiant qui est un composé comportant au moins un groupement amino-(dialkylène phosphonique) et au moins une chaîne polyoxyalkylée, ou un de ses sels. Pour la mise en oeuvre, on effectue avantageusement un pompage du béton au moyen d'un ou plusieurs tubes plongeurs (12) ayant une extrémité d'injection (15) à un niveau inférieur du coffrage.
