摘　　要：从材料科学的角度对比研究了实验室养护28天后各种配比的海工混凝土的力学性能和抗渗透能力.研究表明掺入复合改性剂的海工混凝土与普通海工混凝土相比,抗压、抗折强度和抗渗透能力得到显著提高;较掺混合材料的混凝土而言,抗折能力也有一定的改善.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.
