Abstract

L’invention concerne un procédé de fabrication d’un objet à former en béton moulé. Le procédé comprend notamment, après remplissage en béton d’un moule (60) pour former l’objet à former : la surveillance de la température et des déformations s’exerçant dans le béton remplissant le moule (60) et dans du béton remplissant une éprouvette. Le démoulage de l’objet formé étant déterminé, à partir de la surveillance de la température et des déformations, si l’une des conditions suivantes est remplie : détection d’une inversion de température mesurée dans l’un du béton remplissant le moule (60) et de celui de l’éprouvette, détection, après que les déformations ont commencé à baisser, d’une déformation caractéristique d’un retrait gêné dans le béton remplissant le moule (60). Figure pour l’abrégé : Figure 4BThe invention relates to a method of manufacturing an object to be formed from cast concrete. The method comprises in particular, after filling a mold (60) with concrete to form the object to be formed: monitoring the temperature and the deformations exerted in the concrete filling the mold (60) and in the concrete filling a test tube. The demolding of the formed object being determined, from the monitoring of the temperature and the deformations, whether one of the following conditions is fulfilled: detection of a temperature inversion measured in one of the concrete filling the mold ( 60) and that of the test piece, detection, after the deformations have started to decrease, of a deformation characteristic of an impeded shrinkage in the concrete filling the mold (60).
