Abstract

The invention relates to grout powder for admixture with water to produce grout. The grout powder comprises cement powder and is characterized in that the grout powder has been mixed with a fluorochemical compound. The present invention further relates to a method of preparing grout powder for admixture with water to produce grout, comprising mixing grout powder comprising cement powder with a fluorochemical compound. Still further, the invention relates to an alternative method for making the grout powder, which method comprises treating at least one of the components of the grout powder with a fluorochemical compound.

Claims (15)
