Abstract
The present invention relates especially to a composition for manufacturing an article comprising one or more superposed layers each less than 5 centimeters thick, comprising a hydraulic binder and at least one compound chosen from an organic compound comprising at least two hydrophilic functions and a hydrophobic chain, and a polyamide oligomer. The use of these additives in the presence of hydraulic binder allows the manufacture of articles and coatings with good protection against water uptake, satisfactory water resistance and good mechanical properties such as breaking strength.
