| Résumé : |
The article presents the adhesive properties of a new binder based on epoxy resin with the addition of waste granite powder. The binder was modified with granite powder in amounts ranging from 10% to 60% in relation to the weight of the resin. Moreover, a coating was made without the addition of the granite powder in order to compare the obtained results. Previously obtained pull-off test results were also analyzed. The obtained results confirmed that the optimal material solution includes 10% or 20% of granite powder by weight. Additionally, chemical and microstructural analysis was also performed for both the reference sample and the sample modified with 20% of granite powder. The article also presents an explanation of the reasons for such an improvement of pull-off strength, which is based on careful analysis of the adhesive properties of the epoxy resin bonding agent modified with waste granite powder. Moreover, it explains how granite powder particles penetrate into the near-surface layer of the substrate, examines the porosity of the near-surface layer of the substrate using microstructural analysis, and presents the effect of adding waste granite powder to the epoxy resin bonding agent on the chemical properties of the near-surface layer of the substrate. |
