Figure 8 shows that the variation coefficient of cement dose of vibration mixing is basically smaller than that of ordinary mixing. The average variation coefficient of cement dosage with the 3 and 3.5% C-B-3-1 mixtures under ordinary mixing is 1.4 and 1.7% higher than that of vibration mixing, respectively.
