Abstract

 Composite materials are designed by combining two or more materials with different properties, in order to obtain a product with characteristics unprecedented in relation to its constituents, but suitable for specific applications. Within this context, the present work aims to evaluate the best combination between a polymeric matrix and a ceramic particulate reinforcement to obtain a composite applicable to recovery chemical, physical and mechanical pathologies in concrete structures. In order to make the application feasible, the reinforcement consisted of mesoscopic silica particles, with granular-spherical shape, arising from the Samarco dam disaster in Mariana (MG). Different formulations were evaluated to obtain a performance index linked to the reinforcement volumetric ratio, in order to facilitate the applicability analysis of this product.
