| 摘 要： | 高性能混凝土以耐久性设计优先而不以强度设计优先。采用低水胶比和掺加足量的矿物细掺料与高效外加剂等技术措施是提高混凝土耐久性能的重要手段。要求混凝土具有全面的高性能不仅是不科学的。而且也将造成自然资源的极大浪费，片面强调混凝土的高强度必将影响混凝土耐久性能的提高。在许多情况下，含有碱活性成分的骨料也是可以使用的。

| Abstract: | The design for works of high performance concrete shall be at durability superiority instead of strength superiority.Adopting low water-binder ratio,mixing with sufficient grain mineral admixture and high ef-fective ad ditives are important measures to improve durability.To expect that concrete possesses high performance in all aspects is unpractical,as it may waste a great deal of natural resources.A mere emphases on high strength may considerably impact the durability of concrete.In many circumstances,alkali-aggregate could also be used. |

| Keywords: | high strength concrete high performance concrete durability alkali-aggregate |
