摘要
利用超声波无损检测方法测定混凝土的早龄期弹性模量,研究了混凝土的密度、通过试件的波速以及混凝土的泊松比三个因素对早龄期弹性模量的影响。研究结果表明:混凝土自身密度和泊松比对其弹性模量测定值产生的影响较小,而超声波波速对其的影响最大。
Early-age elastic modulus of concrete is detected through ultrasonic non-destructive examination.The influence of density of concrete, wave speed of specimen and Poisson＇s Ratio of concrete on early-age elastic modulus of concrete are studied.Research results show that the wave speed has the greatest influence to the result of elastic modulus and the others have less influence to it.
