The test make steel cylinder concrete, PVC protection tube cylinder concrete , spray coatings Outside the cylinder concrete and no protective measures on ordinary cylinder concrete in three different strength grade:C25, C35 and C50 , putting in the freeze-thaw cycle in three kinds of environment of 5% sulfate solution, 5% sulfate + 3% chlorine salt solution and distilled water,Analysis of the Research of Ring pressure of the Pile foundation on the influence of the durability of concrete by
more » ... ring the concrete of Pile foundation corrosion mass loss before and after freezing and thawing.Experiments show that:the concrete with protective measures almost has no mass losses with the level of pile foundation concrete in the same corrosive environment,that, s to say ,the durability is good.While the unprotected concrete has mass losses after the freeze-thaw action hitches in three kinds of solution,And the largest mass loss is in the mixed solution,the durability is the worst.
