The present invention relates to a self-leveling composition for floor toppings, characterized in that it is based on Portland cement or on cement mix CM II or CM III, and in that it further comprises at least sand, water and at least one plasticizer which is a water-soluble or water-dispersible organic compound (I) containing at least one aminodi(alkylenephosphonic) group and at least one polyoxyalkyl chain, or at least one salt of compound (I).

Cement-Based Self-Leveling Composition

A method for producing a floor by casting a concrete slab with a concrete composition having a water/cement ratio of 0.4-0.7 and a minimum compressive strength no lower than 10 MPa, and depositing a first covering layer on the freshly cast concrete slab as soon as the slab is capable of bearing the weight of a man walking thereon without being damaged, or once the compressive strength of the slab concrete has reached a value of 0.15-0.4 kg/cm,. Said covering layer is based on a self-levelling composition. The method is useful for producing all kinds of floors for indoor, outdoor, industrial or commercial use.
