论水、土中硫酸盐对混凝土结晶腐蚀的气候与评价

水、土中硫酸盐对混凝土结晶腐蚀,经工程实践和实验研究证明是受宏观气候影响最大的一类腐蚀。我国幅员辽阔,南北跨越50个纬度,有世界屋脊的青藏高原,属高寒地带,有极端干旱的戈壁和沙漠,有干旱的草原,还有湿润的山地、森林、平原和海洋,宏观气候变化极大。该文将我国分为高寒、干旱和湿润三个宏观气候区和六个场地环境类型,从而区别硫酸盐结晶腐蚀和评价,并对工程实践和气候特点作了扼要说明。

Climate and Evaluation of Crystallizable Erosion of Concrete by Sulfates in Water and Soil

It is proved by practice and tests that crystallizable erosion of concrete by sulfates in water and soil is one of the most serious ones influenced by macroclimate.China is a vast land with 50 latitudes from south to north and there are Qinghai-Tibet plateau belonging to high cold zone,the most dry gobi and desert,dry grassland,wet hills,forest,plain and ocean.The macroclimate in China changes greatly.The paper divided China into three climate macroclimate zones and six site environmental types and distinguished different crystallizable erosion and evaluation by sulfates and briefly explanation for engineering practice and climate character.
