Evaluation of Compressive Strength and Stiffness of Grouted Soils by Using Elastic Waves

Figure 6

Compressional wave signatures during compressive strength tests for soil-grout mixtures: (a) specimen without grains: Type P4; (b) specimen with coarse grains: Type C4. Numbers on left side at each figure indicate applied axial stress.
