降低混凝土抵抗各种侵蚀性介质的耐腐蚀性能力
Reduce capacity of concrete to resist the corrosion resistance against all kinds of the erosion media.

混凝土腐蚀有3 种类型：There are three types of concrete corrosion:
① 溶蚀性混凝土腐蚀。即当水通过裂缝渗入混凝土内部或是软水与水泥石作用时，将一部分水泥的水化产物(如Ca(OH)2)溶解并流失，引起混凝土破坏。
① dissolution of concrete corrosion. That is, when the water infiltration through cracks into concrete or soft water interact with cement, it will dissolve part of the cement hydration products (such as Ca (OH) 2) and make them lost, this will cause concrete damaged.
② 酸盐(酸性液体)腐蚀和镁盐腐蚀。这类腐蚀的主要生成物是不具有胶凝性，且易被水溶解的松软物质。这类物质能被通过裂缝或孔隙渗透入混凝土内部的水所溶蚀，使混凝土中的水泥石遭受破坏。
② Salts (acidic liquids) corrosion and magnesium salt corrosion. The main product of such corrosion is not gelled, and easily dissolved in water soft material. Such material could be corrupted by internal water which infiltrated through the cracks or pores of the concrete so that the concrete in the cement will be damaged.
③ 结晶膨胀型腐蚀。它是混凝土受硫酸的作用，在裂缝和混凝土孔隙中形成低溶解度的新生物，逐步累积后将产生巨大的应力使混凝土遭受破坏。
③corrosion of crystallization expansion. That is, concrete under the role of the sulfuric acid, form new biotechnology with low solubility in the cracks and pores in the concrete, and eventually will be gradually accumulated a tremendous stress so that damage the concrete.
影响混凝土结构物的结构强度和稳定性：
Impact of the concrete structure of structural strength and stability:
混凝土裂缝直接影响混凝土结构物的结构强度和整体稳定性，轻则会影响建筑物的外观、正常使用和耐久性，严重的贯穿性裂缝则可能导致混凝土结构物的完全破坏。
Concrete cracks directly impact on the structural strength and overall stability of concrete structure, and if mild it will affect the appearance, normal use and durability of buildings, serious cracks in the cross-cutting could result in the completely destroy of concrete structure.

裂缝引起的漏水问题：water seepage problems caused by
Cracks
根据试验，当裂缝宽度超过自愈范围以内，裂缝漏水量和裂缝宽度的3次方成正比。
According to trial, when the crack width is more than the scope of self-healing, seepage quantity of cracks in direct proportion to the cubic of width

累社咧。。。多加点分
靠，都差点累死还抄。
闲得抄你的。。。别不要脸

我最好........：雨后南风是抄
