When used untreated in concrete mix, the recycled aggregate absorb part of the water initially calculated for the cement hydration, which will adversely affect some characteristics of the recycled concrete. This article seeks to demonstrate that the technique of presaturation is able to solve the aforementioned problem. In order to do so, the water absorption of the aggregates was tested to ...

For structural elements exposed to chloride environments, an important aspect of Recycled Steel Fiber Reinforced Concrete (RSFRC) durability is the corrosion resistance. In the present work, an experimental program was carried out to evaluate the longterm effects of chloride attack on the postcracking behavior of RSFRC by performing splitting tensile tests and round panel tests.
