中文摘要 | 混凝土結構物維修之成效不僅與修補材料之物理及力學性質有關,且與界面結合 效果有密切關係。本文針對強化水泥砂漿、環氧樹脂砂漿、速凝水泥砂漿以及亞克力樹脂砂 漿等具代表性且已商業化的混凝土修補材料,量測其物理及力學性質,並對修補材料與混凝 土底材之結合效果進行試驗。結果顯示,環氧樹脂砂漿及速凝水泥砂漿之凝結時間非常快, 60分鐘即可達到所需的強度,適合於混凝土結構物遭破壞後進行搶修之用。增加維修斷面 的粗糙度可提昇維修斷面的結合效果,尤其以含聚合物的修補材料特別顯著,因此在施工方 便可行的前提下,宜適度增加維修斷面的粗糙度,以確保修補成果。 |
英文摘要 | The performance of the repaired members depends not only on the physical and mechanical properties of the repairing material, but also on the behavior at the bond interface. In this research, repairing materials including improved cement mortar, epoxy resin mortar, rapid setting cement mortar, and acrylic resin mortar were tested for their physical and mechanical properties. Also, flexural and shear tests were performed on repaired specimens to evaluate the bonding effect of repairing material with concrete substrate. It is found that the epoxy resin mortar and rapid setting cement mortar set very fast and develop considerable strength within 60 minutes. Hence these materials are suitable for emergency repair of damaged concrete structures. Test results also indicate that increase in the roughness of repairing surface improved the bonding between repairing material and substrate concrete. Such a phenomenon is most pronounced for polymer repairing materials. Therefore, under feasible construction conditions, it is recommended that the surface roughness of the repairing section be increased. |
