裂縫對鋼筋混凝土腐蝕之影響探討

The Crack Influence on the Corrosion of the Reinforced Concrete

混凝土梁構件的腐蝕損害為現今許多建築物破壞的主因，而導致其腐蝕損害的原因有氯離子誘發鋼筋發生腐蝕生銹、混凝土碳化、施工的疏忽等，主因則是裂縫的產生。本文主要探討如何有效防止裂縫的產生及延伸的方法，期能減少裂縫發生並減緩鋼筋不遭受腐蝕，有利於鋼筋混凝土之耐久性控制。

Corrosion to Reinforced Concrete beam is one of the main causes and will damage the RC structure. There are many corrosive coefficients such as steel corrosion induced by chloride. Concrete carbonization and working negligence. But initialed from the occurrence of the crack. In this paper .We discuss the formulation of the crack and the crack reductions in the concrete members. It is anticipated that the durability of concrete will be enhanced by reducing cracks.
