Self-leveling concrete
The invention relates to uniformed concrete comprising, in percentages by weight, (d) 87% to 98% of particles comprising more than 90 wt.-% alumina, (c) 1% to 7% silica fume particles, (f) 1% to 8% particles of a hydraulic cement, the fraction of said particles having a size less than 40 μm being distributed as follows, in percentage by weight in relation to the weight of the unformed concrete: fraction <0.5 μm: ≧4%, fraction <2 μm: ≧5%, fraction <10 μm: ≧19%, fraction <40 μm: 34%-52%, fraction between 2 μm and 40 μm: 26.5%-34%, the concentration of Zro2, in percentage by weight on the basis of the uniformed concrete, being less than 2%, and the concentration of organic fibres, in percentage by weight on the basis of the uniformed concrete, being less than or equal to 0.03%.
