Some Aspects on Grout Time Modelling

Abstract
Grouting has been used for many years as a sealing method for hard jointed rock and the method has been improved in a number of ways, but still there is a lack of parameters relating the sealing effort to the sealing efficiency. The grouting time is therefore here suggested as a parameter, which could be considered to improve the sealing result. It is also suggested that the grouting time is correlated to the rock mass joint system situation, where a long or short grouting time will for different rock mass joint situations mean different design. Both the grouted volume and the grouting time has an influence on the filling of the joint system in the rock mass. The time needed for sealing should be considered especially when the demand on sealing efficiency is high. The effect of grouting time is presented and discussed in some examples.
