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