混凝土结构因耐久性不足所造成的直接和间接损失都很巨大。引起混凝土耐久性失效的是多种因素共同作用的结果,耐久性问题是一个十分重要也迫切需要解决的问题。因此,我们更需要从环境层次、材料层次、构件层次和结构层次对混凝土耐久性进行研究,进行正确的设计和严格的施工,这样,才能保证我国建筑事业蓬勃的发展。 The direct and indirect losses of concrete structures due to lack of durability are enormous. The cause of concrete durability failure is the result of a combination of many factors. Durability is a very important and urgent problem to be solved. Therefore, we need to study the concrete durability from the environmental level, the material level, the component level and the structural level, carry on the correct design and strict construction so as to ensure the vigorous development of our country’s construction.
