Prediction of Ultrasonic Pulse Velocity for Cement, Mortar, and Concrete through a Multiscale Homogenization Approach

Autor: Jingluo Jiang, Dawei Zhang, Fuyuan Gong, Dian Zhi

Publikováno v: Materials, Vol 15, Iss 9, p 3241 (2022)

Ultrasonic testing (UT) is an important method for concrete, and ultrasonic pulse velocity is commonly used to evaluate the quality of concrete materials in existing studies. The ultrasonic pulse velocity of concrete materials is affected by many fac
