Reinforcement corrosion in self-compacting concrete made with waste filler of bituminous mixtures

This study aims to investigate the properties of self-compacting concrete (SCC) manufactured with a recovered filler (RF) that comes from hot-mix asphalt plants. This material is a waste that sometimes implies an environmental problem and its use in the manufacturing of concrete could be solved it and would be a new sustainable way of casting concrete. The use of this material did not compromise the self-compacting character of the concrete. Durability properties are barely studied when a new product is incorporated to a construction material. This work estimates the service life related to reinforcement corrosion of a SCC elaborated with the waste from hot-mix asphalt plants. Mechanical properties were studied, especially those related to its behaviour against rebar corrosion, and according to the results, this SCC might allow structure durability similar to those elaborated with conventional raw materials. In other words, acceptable service life will be achieve based on carbonation as well as chloride penetration. Furthermore, good behaviour against shulphates has been demonstrated.
