Abstract

La présente invention concerne un nouvel activant de la prise du laitier. Selon une mise en oeuvre préférée de l'invention, cet activant est caractérisé en ce qu'il se compose de chaux et de gypse, le pourcentage en poids de la chaux comptée en CaO par rapport au laitier étant compris entre 0,35 et 0,5 %, celui du gypse par rapport au laitier étant compris entre 2 et 10 %. L'activant de la présente invention est en particulier applicable aux compositions sables-laitiers granulés pour les travaux de voirie et les constructions d'immeubles.The present invention relates to a novel slag uptake activator. According to a preferred embodiment of the invention, this activator is characterized in that it consists of lime and gypsum, the percentage by weight of the lime counted as CaO relative to the slag being between 0.35 and 0 , 5%, that of the gypsum relative to the slag being between 2 and 10%. The activator of the present invention is in particular applicable to granulated sand-dairy compositions for road works and the construction of buildings.
