PROCESS FOR THE MANUFACTURE OF INFRASTRUCTURES BASED ON VITRIFIED DAIRY BLAST FURNACE AND ADDITIVE USED

摘要

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 mum 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 mum.
