侵蚀性介质 meaning in English
aggressive medium
Examples
- For concrete structure in the practical engineering , the non - mechanics damages , such as alkali - aggregate reaction , sulfate attack , carbonization , steel rust , freeze and thaw , and so on , are unavoidable due to the exist of erosive media . the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly , and shortens the service life of the concrete to a large extent . permeability of concrete is the most important factor for these non - mechanics damages , so the permeability test of concrete is the normal and required item to study the durability of concrete
实际工程中的混凝土结构，因侵蚀性介质的存在而使非力学破坏行为无处不在，这些非力学破坏行为包括碱集料反应、硫酸盐侵蚀、碳化、钢筋锈蚀、冻融等，单一的破坏形式或多形式的复合破坏作用对混凝土结构性能及耐久性能均有着较为严重的影响，在很大程度上缩短了建筑物的服役年限，而这些非力学破坏在很大程度上取决于其渗透性，所以测试混凝土渗透性能是研究判断混凝土耐久性的常规必测项目。 - The proportion of plastic shrinkage cracking is rather high in early cracking . the plastic shrinkage cracking would effect construction appearance and promote the propagation of drying shrinkage cracking or other types cracking , but also provide a passage for aggressive agents penetrating and moving to the concrete mass
塑性收缩裂缝在早期裂缝中占有相当大的比重，其存在不仅影响工程外观，促使干燥收缩裂缝或其它形式裂缝的发展，而且还将为侵蚀性介质向混凝土基体渗透、迁移提供通道，对混凝土的耐久性造成严重影响。
