[摘要] 混凝土结构住宅在一、二、三类环境中，按现行规范设计使用年限为50年。分析混凝土结构劣化的内因和外因，采取措施，克服劣化的内因，隔断劣化的外因，提高混凝土结构耐久性，使混凝土结构住宅使用年限成倍地提高。由此可节约大量资源和能源。应制定住户标准建筑面积，提倡高层，限制低层及别墅式住宅。用征收土地使用税办法，对低标准住户优惠，对超标准住户多征土地使用税，达到节约土地资源的目的，使住宅建筑可持续发展。同时国家应对成倍提高使用年限的住宅实行优惠政策，对此类住宅给予经济补贴。

Abstract: It is a life of 50 years of concrete structure housing in the first, second and third type of environment, according to the current standard design. Analyze the internal and external causes of concrete structure deterioration and take measures, overcome the internal and external factors of deterioration, and improve the durability of concrete structures to make sure the life of concrete structure housing doubled and redoubled. This can save a lot of resources and energy. The household standard building area should be planned. The high rise building should be promoted and the low rise building as well as the villa-style houses should be limited. By the way of levying on land-use tax, do referential rights to the low standard household users and levy on more land-use tax to ones beyond the standard to fulfill the aims of the conservation of land resources and the sustainable development of residential construction. At the same time, the country should make preferential policies to the housing whose life will be double improved, and provide financial subsidies for such housing.
Keywords: concrete structure; deterioration; durability; the life of the housing construction
