Ultrasound transmission method to assess raw earthen materials
Rights accessOpen Access
The feasibility of using ultrasound transmission method to assess raw earthen materials is investigated. Results indicate that this technique is effective at controlling the drying process of raw earthen materials. Near the hygrometric equilibrium, there is a linear relationship between the moisture content of the earthen material and the ultrasound transmission speed, which increases during the drying process. For the tested compressed earth, the hygrometric equilibrium is reached when the ultrasound transmission speed is over 1100 m/s. In addition, ultrasound transmission method is useful to reliably calculate the dynamic Young's modulus of raw earthen materials.
