摘要
本文阐述了用超声波法测定水泥砂浆弹性模量的基本理论，并用超声波法和常规方法测定了２种不同配比的水泥砂浆在２种不同养护条件下不同龄期时的弹性模量。以常规方法的试验结果为基础分析了超声波法测定结果的可靠性。为在工程上使用超声波法测定材料弹性模量提供了一定的依据。
This paper explains the foundamental theory to determine the module of elasticity of concrete mortar with ultrasonic. With the ultrasonic and conventional method themodule of elasticity of two kinds of concrete mortar with different components under different curing condition and at different ages are determined. Based on the experimental result ofconventional method the reliability of results of ultrasonic method is analysed,therefore a criterion should be provided for the use of ultrasonic in engineering to determine the module ofelasticity of concrete mortar.
