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 measuring 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.
