Abstract
The properties of mortar and concrete are improved by the addition to the fresh mortar or concrete of an aqueous dispersion of a plastic obtained by the emulsion polymerization of olefinically unsaturated monomers, and of a polycondensate of formaldehyde and an amino-s-triazine modified with sulfite or sulfonic acid. A well-balanced relation between the compressive strength, the tensile strength in bending, and the adhesion to aged and hardened mortar or concrete is thus obtained.
