Concrete mixtures or mortar mixtures or concretes or mortars and process for their production

A concrete or mortar mixture of concrete or mortar on the basis of hydraulic binders and plastic materials for the production of building elements or coatings insensitive to shock and impact stress, abrasion, frost-thaw and defrosting salt and chemical attack as well as for effecting repair work on building elements or coatings, wherein lime or cement selected from the group of Portland cement of conventional composition, iron Portland cement, blast furnace cement, flue ash Portland cement, Ciment compose, puzzolane cement, high-alumina cement, modified Portland cement on the basis of 11CaO.7Al.sub.2 O.sub.3. CaF.sub.2, Brunauer cement, Grenoble cement and Roman cement and further at least one liquid-dispersed or dissolved plastic material consisting essentially of a polymer of an ethylemically unsaturated monomer having low-temperature adhesiveness and a T.sub.max value of less than -8.degree. C. determined by DIN 53445 and, in addition to said components bitumen or tar in ground, dry-dispersed, liquid-dispersed or dissolved form are contained.
