摘要
论述了超声脉冲穿过硬化过程中的水泥浆时超声频谱的变化,并分析了声速、频率幅值与水泥浆期龄之间的关系.
This paper described the variations of frequency spectrum when ultrasonic pulse transfered at cement paste in hardening process and analysed the relation among the velocity,frequency,amplitude of ultrasonic and age of cement paste from testing results,the ultrasonic frequency spectrum was an effective method to investigate variation of early structure of hardening cement paste and determine the setting time of cement.
