活性粉末混凝土的研究与应用进展

Advance of research and application on reactive powder concrete

活性粉末混凝土是一种具有高强度、高耐久性及良好韧性的新型水泥基复合材料,具有广阔的研究与应用前景。本文介绍了RPC的配制原理和基本性能,概述了其研究与应用现状;探讨了目前研究中存在的问题,为将RPC应用到现浇结构中,提出放宽对骨料粒径和成型及养护条件的限制等措施;讨论了RPC的发展趋势,认为应进一步对RPC的抗震、抗火等抗灾性能进行深入研究。

Reactive Powder Concrete (RPC) is a new kind of cement-based composite material that has ultra-high strength,high ductility and good toughness.Over the decade,because of its extensive prospect of application,much research has been undertaken on it.The paper firstly introduced its base fabricative principle,mechanical properties and present states of research and application.Then,in order to use it in cast-in-place structures,some advices that relaxing the size of aggregate and curing condition were presented.Finally,the trend in development of RPC is described.The focus should be placed on seismic and fire-resistant performance of RPC.
