【Abstract】 For concrete foundations in acid soil,durability is the key issue.In order to make corrcsion-resistant concrete,aquality evaluation system is built by the authors to control the quality of concrete in corrosive environment,consisting of several indexes and evaluation methods.The authors also put forward several principles and guidelines for designing concrete mixing ratio;and relying on this,a reference design is given and applied to labaratory test;then an accelerated corrosion test is made on the designed product.According to the test,the thinnest thickness of concrete cover is given by the author to make sure the designed concrete has a duration of at least 50years in acid soil.更多还原
