  3. 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

    實際工程中的混凝土結構,因侵蝕性介質的存在而使非力學破壞行為無處不在,這些非力學破壞行為包括堿集料反應、硫酸鹽侵蝕、化、鋼筋銹蝕、凍融等,單一的破壞形式或多形式的復合破壞對混凝土結構性能及耐久性能均有著較為嚴重的影響,在很大程度上縮短了建築物的服役年限,而這些非力學破壞在很大程度上取決于其透性,所以測試混凝土透性能是研究判斷混凝土耐久性的常規必測項目。
