| Industrial waste from the production of metallic silicon and silicon–iron alloys, whichincludes silica fumes (microsilica), is subject to numerous applications aiming at its reuse in concreteand polymeric composites. Recycling solves the problem of their storage and adverse environmentalimpact. Six different formulas of epoxy resins were tested, differing in the type of polymer, the mixingprocess (sonication or not) and the presence of microsilica. The study showed that microsilica addedto the epoxy resin changes its viscosity and free surface energy, and these are the parameters thatdetermine the adhesion of the polymer to the concrete surface. Strength tests and SEM analysis havedetermined how microsilica molecules can penetrate the structure of polymer macromolecules byfilling and forming temporary chemical bonds. Mixing the fillers with the adhesive was achievedby using a sonication process. The analysis of the obtained results showed that, depending on theinitial composition of the polymer, the addition of microsilica can change the chemical, physical andmechanical properties of the hardened adhesive to varying degrees. In the case of adhesives usedin the construction industry to strengthen and glue structural elements, these changes significantlyaffect the durability of the adhesive joints. |
