| Summary: | Using epoxy to repair concrete crack is widely used for restoring concrete structure. Epoxy is used as a base material in composite materials with fillers to improve mechanical and physical properties. The study aims to modify the properties of the epoxy by adding (alumina, silicon carbide, silica fume, pumice) and using This compound is for repairing concrete cracks.
Each of the materials (alumina, silicon carbide, silica fume, pumice) were used to harden the epoxy in different proportions (5, 10, 15) by weight. It has particle sizes (45 - 65 μm), to prepare composite particles that can be used in construction applications. Further tests are performed to verify whether or not composites are suitable for applications. For the crack repair application, the resulting composites were tested for compression and bending.
The resulting compound was applied to treat cracks in previously prepared concrete samples and several tests were performed (compression, bending, and UPV) to determine the effectiveness of this compound in treating cracks in the structural elements. |
