ABSTRACT:
A dispersion of a polymer such as an acrylic resin, and of a surface-acting resin, such as a melamine resin, is added to a cement mortar having a sand-to-cement ratio of 1 to 3 and a water-to-cement ratio of 0.25 to 0.35, the resin being preferably approximately 10 parts by weight per 100 parts of cement. This blend is applied to the interior of a pipe and the pipe is rotated at a speed which is gradually increased in order to produce at least approximately 20-g forces on the material for compacting same for a few minutes.
