混凝土的耐久性是个很古老的话题,又是当前十分关注亟待解决的难题。近几十年来由于混凝土耐久性不足引起工程结构过早破坏拆除或失效不得不进行维修与加固,造成了巨大的经济损失,这是各国普遍存在的现象,因而引起学术界、工程界、设计以及政府职能部门的高度重视和共鸣,也成为当前国内外混凝土领域中研究的热点。近年来,我国混凝土耐久性研究和应用的进展情况如何?就此问题本刊编辑部专访了曾参与国家“九五”攻关项目“重点工程混凝土安全性的研究”并承担了混凝土抗冻性研究和混凝土抗腐蚀研究两个专题五个子题研究工作的中国水利水电科学研究院教授高工、中国土木工程学会混凝土与预应力混凝土分会混凝土耐久性专委会主任李金玉,现将访问内容及其研究成果整理刊出,以饷读者。
Durability of concrete is a very old topic, but also the current very concerned about the problems to be solved. In recent decades, due to the lack of durability of concrete caused by premature destruction of the structure of the demolition or failure have to be repaired and reinforced, resulting in huge economic losses, which is a common phenomenon in various countries, which led academics, engineering, design and The government departments attach great importance and resonance, has become the current focus of the field of concrete research at home and abroad. In recent years, China’s concrete durability of the progress and application of the situation? On this issue editorial department has participated in the national “95 ” research project “key project of concrete safety ” and assume the concrete resistance Frost research and corrosion resistance of concrete two topics five sub-topics of Chinese Academy of Water Conservancy and Hydropower Research Professor Gao, China Civil Engineering Society Concrete and Prestressed Concrete Branch Concrete Durability Director Li Jinyu will now visit the content Collected and published its research results, to readers.
