Abstract

The exhaustion of natural aggregate deposits and the difficulties of opening new quarriesmake it necessary to look for new sources of supply. Recycling and recovery of waste are nowconsidered a solution for the future in order to meet the shortfall between production andconsumption and protect the environment. The objective of this study is to evaluate the effect ofactive mineral additions (Pozzolana, slag and silica fume) and inert (calcareous) on the behavior ofconcrete using recycled fine aggregates. The results obtained in this experimental study allow usto draw the conclusion that the use of additions (pozzolana , limestone fillers, silica fume and slag)improves the physico-mechanical and, more particularly, rheological characteristics of concretesbased on 50% of recycled fine aggregate.
