ABSTRACT:
The invention relates to an hydraulic binding agent with a controlled setting time, which attains high strength from the beginning of setting.
The hydraulic binding agent is prepared from (a) 85 to 99.89% cement clinker, with the specific surface area of 150 to 3000 m.sup.2 /kg and with 5 to 95 weight % of particles smaller than 5 .mu.m, (b) 0.01 to 10 weight % salt of sulfomethylated condensation product of phenols with formaldehyde wherein up to 70% of the acidic groups are coupled by a trivalent cation from the metal group consisting of iron, aluminum and chromium, (c) 0.1 to 10 weight % alkaline hydroxide, carbonate, hydrogencarbonate, silicate, hydrogensilicate, hydrogensulfite or oxalate, and (d) at least 20 weight % of formation water. The condensation product may be partly oxidized.
The hydraulic binding agent is suitable for numerous purposes in the building industry.
