| Abstract: | In this paper, an experimental study of utilizing a polymer-KETAl（KT） to produce a higher durability concretes for marine is presented. Both flexural and compressive strength of the composites after 28 days curing were tested. Chloride penetration of the composites was also analyzed by using NEL. Resuhs show that the addition of KT increases both flexural and compressive strengths for the ordinary concrete, although KT had a negative eft~ct on the compressive strengths for concrete incorporating active addition（fly ash or slag）. Results also show that the addition of KT significantly enhances the performance of resisting CI- penetration for all samples. |
