Notes:
Figure 1
Gel time expressed in minutes
In column A the pH of the solution is reported.
In row 1 the electrolyte concentration of the accelerator is reported
Form B3 to I11 the experimental gel time is reported.

Figure 3
In column A the experimental gel time is reported
In colum B the slope of the viscosity curve, once gelled is reported. Slope was calculated between 1000mPas and 4010 mPas.

Figure 4
Viscosity measured by means of Brookfield digital viscosimeter Model DV-II
For each test, the first column is the viscosity in mPas, and the second column is the time elapsed from the mixing expressed in minutes.

Figure 5
Comparison between the experimental gel time (first column) and predicted gel time (second column) is reported.

Figure 6
Experimental viscosity curves for different grout designs are compared. For each case, the first column is the elapsed time (minutes) and the second column the viscosity (mPas).
