摘要
利用液压加载和超声波无损检测两种试验方法,对多种强度等级的混凝土材料早期弹性模量进行了相应的试验研究,对超声波无损检测混凝土早龄期弹性模量方法的正确性进行分析论证,并对试验结果进行回归分析,提出超声波无损检测方法推算混凝土静弹性模量公式。
This essay takes two testing methods, namely hydraulic loading and ultrasonic nondestructive testing, to carry out corresponding experimental study on early-elastic modulus of the concrete material of a variety of strength, and to analyze the validity of Ultrasonic nondestructive testing on the elastic modulus of early age concrete.This essay brought forth regression analysis based on the experiment results, and put forward the formula to determine static elastic modulus of concrete using Ultrasonic Non-destructive Detection methods.
