环境污染除了影响建筑物的外观与表层以外,还大大地影响了结构的耐久性。纯净的空气中含有0.03%的 CO_2。环境的污染使空气中的 CO_2含量增加。世界人口的快速增长,资源和能源的消耗量也在迅速增加,生产和生活排放出的种种化学物质,增加了环境的污染。这些污染不仅危害人的健康。而且对建筑物的耐久性也产生很大的影响。污染物中的侵蚀性介质对钢筋混凝土结构产生破坏作用,严重影响了钢筋混凝土结构的耐
In addition to the impact of environmental pollution on the appearance and appearance of the building, but also greatly affected the durability of the structure. Pure air contains 0.03% CO 2. Environmental pollution increases the amount of CO 2 in the air. The rapid growth of the world’s population, as well as the rapid increase in the consumption of resources and energy, and the emission of chemicals from production and daily life have increased the pollution of the environment. These pollution not only endanger human health. But also has a great impact on the durability of the building. Erosive pollutants in the medium have a damaging effect on the structure of reinforced concrete, seriously affecting the resistance of reinforced concrete structures
