对于钢筋混凝土掺用少量氯盐的蓄热法冬季施工,近来发生了一些事故,争议的焦点是掺氯盐的钢筋混凝土中钢筋的锈蚀问题。对此,我院以及各有关单位曾进行了多次调查,并作了一些必要的试验。从调查和试验的结果来看,钢筋锈蚀主要发生在使用范围不当、构件本身混凝土密实度不够或钢筋保护层太 For the winter construction of reinforced concrete mixed with a small amount of chlorine salt in the thermal storage method, some accidents have occurred recently. The focus of the controversy is the corrosion of steel bars in reinforced concrete mixed with chlorine salts. In this regard, our hospital and all relevant units have conducted several investigations and made some necessary tests. From the results of investigations and tests, the corrosion of reinforcing steel mainly occurred in improper use, the concrete itself was not dense enough, or the reinforcing steel layer was too thick.
