Abstract
A process for constructing infrastructures, in which aggregates, vitrified blast-furnace slag, a pulverulent activator and water are mixed together, the mix is spread out over the ground, compacted and left to harden, and in which a particulate slag and a ready-prepared additive containing, on the one hand, the activator and, on the other hand, dry ground vitrified slag having a particle size of less than 500 &mgr;m are added to the aggregate is provided. Further provided is the additive for the construction of infrastructures according to the said process, which additive includes, on the one hand, a pulverulent activator and, on the other hand, dry ground vitrified slag having a particle size of less than 500 &mgr;m.
