Abstract (en)
[origin: WO2006122754A1] The invention relates to the use of epoxy derivatives that are obtained by reacting a di-, tri- or tetraglycidyl compound (A) with an optionally unsaturated reactive component (B), consisting of C<SUB>8</SUB>-C<SUB>28</SUB> fatty acid, a C<SUB>8</SUB>-C<SUB>28</SUB> alcohol or a C<SUB>8</SUB>-C<SUB>28</SUB> secondary amine, as additives for cementitious building materials. The inventive epoxy derivatives are excellent agents for preventing or suppressing blooming on the surfaces of cured cementitious building materials and/or for hydrophobing the corresponding cementitious systems. Due to the integration of the inventive additives, the cementitious products absorb substantially less water, thereby reducing damages caused by frost and rapid rust formation on the reinforcing steel.
