Valorisation des LAC dans les mélanges granulaires
This article in three parts deals with the degradation of Basic Oxygen Furnace Slag (BOF Slag) in wet media and associated expansion of granular mixtures containing these materials. The part 1 proposed a model of degradation based on the quantification of the damages observed in time by different BOF Slag placed in aqueous media with various temperatures. The present article concerns the measurement of steam expansion realized on the same products, in the CBR mould adapted to the expansive test. The data allowed characterizing the obtained hyperbolic curve, according to the granular packing density and of a “free equivalent lime content” which depends on the age and on the size of grains. The third part uses the results of the both previous models to consider the expansion of every granular mixture. Then, this set can be used to formulate granular mixtures of controlled expansion and help to the valorization of the BOF Slag in road.
