Recycled aggregates, chloride, durability, concreteAbstract
In this work, the replacement of recycled aggregates and its effect on durability were studied through the chloride ion migration test (NordTest 492) and the development of concrete strength using replacements of 30%, 50%, 75% and 100% of the fine fraction of the aggregates. The results showed that it is feasible to develop resistances in concrete with 30% and 100% replacements, from normal aggregate to recycled fine aggregate; the replacement percentages influenced the capillary absorption and the migration of chloride ions, modifying the behavior before durability tests.
