活性粉末混凝土长期性能与耐久性研究进展

Research progress of long-term performance and durability of reactive powder concrete

与一般混凝土相比,活性粉末混凝土因具有超高韧性、超高强度等优点而得到广泛关注。首先从制备原理方面简要介绍了活性粉末混凝土的制备技术及其技术性能。然后重点综合评述了国内外关于活性粉末混凝土在抗冲击、抗疲劳、抗氯离子等长期性能与耐久性方面的最新理论研究成果和试验。并针对需进一步研究的问题提出了建议。

Compared with ordinary concrete,reactive powder concrete has received extensive attention because of its ultra-high toughness and ultra-high strength.The preparation technology and performance characteristics of reactive powder concrete are briefly introduced from the aspect of configuration principle.The latest theoretical research achievements and experiments on the performance of reactive powder concrete in the long-term performance and durability of anti-impact,anti-fatigue,resistance to chloride ion and so on are reviewed comprehensively.Some research topics deserved further studies are proposed.
