| Summary: | 碩士 === 朝陽大學 === 營建工程系碩士在職專班 === 89 === When the concrete structure appears cracks or spalls, it might be repaired by the ordinary cement mortar and not by the appropriate repairing materials. After above concrete repair, it could hardly get the result of expectation and might cause the insufficiency of safety and endurance. Therefore, a complete reference handbook may be useful to the people who are engaged in concrete repair.
People start to pay attention to the corrosion which was caused by the Chloride ion in the reinforce concrete structure, since the cases of the reinforce concrete building containing sea salts were happened. Chloride ion could accelerate the corrosion of steel which leads the reinforce concrete to crack and spall. That may decrease the compressive strength of concrete and the safety of structure. So it is suggested that structural concrete of penetration and endurance could be evaluated by the chloride ion penetration test.
This study was divided into two parts. One part is to translate a hand book of reference on the surface of concrete repair technology. The other part is the experiment and investigation of the chloride ion penetration test for the materials of concrete repair. By the results of this study may provide better technology and durability on concrete repair and repair materials.
