    Abstract: 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/cm2. 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.
