A composition of a solution of a metal salt of a dioic acid that provides corrosion resistance and moisture resistance is disclosed for application to post-construction materials. The composition may further include an effective amount of a thinning agent, e.g., isopropyl alcohol, ethanol, xylene or similar composition, for application directly to the surface of the post- construction material. The composition is effective for reducing corrosion of post-construction materials, including unreinforced concrete or reinforced concrete, and reduces the permeation of moisture and/or the extension of cracks/fissures within the post-construction material. The composition may be applied to the post-construction material through brush applications, spray applications, mist applications or the like. Figure 1 is a macro cell current test graph of voltage vs. time for a post-construction cement article treated according to an exemplary embodiment of the present disclosure.
L'invention porte sur une composition composée d'une solution d'un sel métallique d'acide dioïque qui confère des qualités de résistance à la corrosion et de résistance à l'humidité aux matériaux post-construction. La composition précitée peut en outre comprendre une quantité efficace d'un agent fluidifiant, par ex. de l'alcool d'isopropyle, de l'éthanol, du xylène ou une composition similaire, lui permettant d'être directement appliquée sur la surface du matériau post-construction. La composition de l'invention permet de réduire la corrosion des matériaux post-construction, y compris du béton armé ou non armé, et de réduire la pénétration de l'humidité et/ou l'extension des fissures et craquelures à l'intérieur du matériau post-construction. La composition peut être appliquée sur le matériau post-construction à la brosse, par pulvérisation, par brumisation ou analogue.
