ABSTRACT OF THE DISCLOSURE: High strength cement conglomerates are produced by adding to a mix of water, inorganic binder and aggregates a mixture containing 5 to 99.9% by weight of a polymer obtained by poly- condensation of an aldehyde with a sulphonic acid of the aromatic series, free or salified and soluble in water, and 0.1 to 95% by weight of a product of the hydrolysis of starch obtained from a raw vegetable material, the mixture being added into the mix in an amount of from 0.01 to 3% of the weight of the binder. Water soluble inorganic electrolytes may advantageously be added to the mixture for significantly improving the characteristics of fluidity and cohesion of the fresh mix, and the characteristics of strength of the hardened mix.
