超高性能混凝土抗冲击性能研究进展
Research Progress on Impact Resistance of Ultra High Performance Concrete
摘要
Abstract
Ultra high performance concrete(UHPC)is a cement-based composite with ultra-high strength,good toughness and excellent durability.These excellent properties of UHPC will make it have good application prospects in defense project and some especial projects such as offshore structures, underground space, nuclear waste containers and nuclear reactor shield, etc.To meet the needs of impact resistance and anti-blast in the structures,it is very important to study the dynamic properties of UHPC.Based on the systematic review and summary of the achievements on experimental studies and numerical simulation of impact resistance in UHPC at home and abroad, the existing problems and improvement measures of impact compression test and dynamic tensile test using Hopkinson bar were elaborated.The factors effecting impact property including strain rate, material composition and the number of impact were analyzed.The key problems ensuring the effectiveness of numerical simulation on impact test of UHPC were discussed.Finally,suggestions are proposed for the future research of UHPC impact resistance.It is of purpose to provide guidance to the research of dynamic performance in UHPC and the application of UHPC in practice.关键词
