早龄期混凝土静力与动力损伤特性的试验研究

Experimental research on the damaged characteristics of concrete at early age and subjected to static or dynamic load

本文对早龄期掺合粉煤灰混凝土受静、动力作用的几个问题，包括对当时强度的影响，尺寸效应的影响，２８天后强度的影响，二次受振动的影响，以及受到重大动力损伤的后期强度影响等进行了试验与理论分析．

An experimental research and analysis with damaged mechanics on influences of static and dynamic loads on the early age strength of concrete have been presented in this paper.The influence factors include early ages,dimension effect of concrete samples,vibrations in twice.and severe dynamic damage and so on. On the basis of above-mentioned researches some conclusions with practical significance were drawn.
