Abstract：The compressive strength of concrete under 5~85 ℃ cool/thermal cycling was improved by EVA,polypropylene fiber, and both of them. The improvement effects of adding EVA or polypropylene fiber only and adding the mixture of EVA and fiber were discussed also. The experimental results showed that,only adding EVA had no obvious improvement effect on the compressive strength under the cool/thermal cycling;only adding fiber could reduce the loss rate of compressive strength to a certain degree;the improvement effect of adding the mixture of EVA and fiber was the best,especially in the later period of cool/thermal cycles.
