| titleOfInvention | Ultra-high-performance, self-compacting concrete, preparation method thereof and use of same |
| abstract | The invention relates to an ultra-high-performance, self-compacting light-coloured concrete comprising: a cement; a mixture of calcined bauxite sands of different grain sizes, the finest sand having an average grain size of less than 1 mm and the thickest sand having an average grain size of less than 10 mm; optionally silica fume, whereby 90 % of the particles thereof have a size of less than 1 µm and the average diameter is approximately 0.5 µm, said silica fume representing at most 15 parts by weight per 100 parts of cement; an antifoaming agent; water-reducing superplasticiser; optionally fibres; and water. The inventive concrete also comprises: ultrafine calcium carbonate particles having a specific surface area that is equal to or greater than 10 m2/g and a form factor (IF) that is equal to or greater than 0.3 and, preferably, equal to or greater than 0.4. The grain size distribution of the cements, sands, ultrafine calcium carbonate particles and silica fume is such that at least three, and at most five, different grain size ranges are present, the ratio between the average diameter of one grain size range and that of the range immediately above is approximately 10. The invention also relates to the method of preparing one such concrete and to the uses thereof. |
