Self-levelling concrete

CONSALES THIERRY / GAUBIL MICHEL

A powder including, in percentages by weight: (a) 94% to 99% of particles of at least one refractory material, the main constituent(s) of which are alumina and/or zirconia and/or silica; (b) 1% to 6% of a hydraulic cement; (c) 0 to 0.03% of organic fibres; (d) optionally, 0.075% to 1% of a surfactant; and (e) optionally, a setting accelerator, where the fraction of particles having a size below 40 [mu]m being distributed, in percentages by weight relative to the weight of the powder, in the following manner: (1) fraction<0.5 [mu]m:>=4%, (2) fraction<2 [mu]m:>=5%, fraction<10 [mu]m:>=16%, and fraction<40 [mu]m:29-45%, where the proportion of zirconia in the fraction of particles having a size smaller than 10 [mu]m, called 'fines', is between 35% and 75% by weight relative to the total weight of said fraction.
