BETONS A ULTRA HAUTE PERFORMANCE NON AUTOPLACANT
La présente invention se rapporte à un liant hydraulique comprenant en pourcentage en masse : - de 20 à 82 % d'un ciment Portland dont les particules présentent un D50 compris de 2 µm à 11 µm ; - de 15 à 56 % d'une addition minérale A1 non pouzzolanique, dont les particules présentent un D50 compris de 1 à 150 µm ; - au moins 4 % d'addition minérale A2 pouzzolanique, dont les particules présentent un D50 compris de 1 à 150 µm ; la somme de ces pourcentages étant comprise de 90 à 100%.
A hydraulic binder includes in mass percent from 20 to 82% of a Portland cement the particles of which have a D50 comprised from 2 μm to 11 μm; from 15 to 56% of a non-pozzolanic mineral addition A1, the particles of which have a D50 from 1 to 150 μm and selected from among limestone additions, siliceous additions, siliceous limestone mineral additions, calcined shales, zeolites, burnt plant ashes, and mixtures thereof; from 4 to 30% of pozzolanic mineral addition A2, the particles of which have a D50 from 1 to 150 μm; a sum of the percentages of the Portland cement, the non-pozzolanic mineral addition A1 and the pozzolanic mineral addition A2 being comprised from 90 to 100%.
