Performance Evaluation of Multi-axis Fiber Net in Pin-net External Wall Repairing

Abstract

For long-term and effective use of the building stock, external wall repairing is getting more important. Pin-Net external wall repairing is one of the external wall repairing. Now, there are some studies for evaluation of each Pin-net external wall repairings, but there are only a few studies to compare the characteristic of them in term of the same viewpoint. In addition, it is necessary to compare the repairings from the viewpoint of resistance of concrete crack opening. In this study, using 6 types of the multi-axis fiber net, we did a tensile test for bond strength of the nets and 3-point bending test, to compare the characteristic of the nets in Pin-Net external wall repairing.
