    摘要: The invention relates to a bonding pre-mixture containing: 0.2% to 63% of a material of an ultrafine granulometric class that contains individual D90 particles of less than 1 μm and/or of a specific BET surface area greater than 5 m
    2 /g; 8% to 63% of selected Portland cement that contains D90 particles of less than 30 μm; and 25% to 85% of a material, other than the cement, of a fine granulometric class that contains particles, the D10 and D90 of which are 1 μm to 120 μm and of a specific BET surface area greater than 5 m
    2 /g. The invention also relates in particular to a bonding mixture that contains particles, the D10 and D90 of which are 120 μm to 5 mm, in addition to the pre-mixture of a material of a medium granulometric class.

    摘要: The invention relates to a dry binder pre-mix containing by weight percent: Portland clinker in the form of grains having a Dv97 varying between 10 and 30 μm or having a Blaine specific surface area greater than or equal to 5300 cm
    2 /g, preferably greater than or equal to 5500 cm
    2 /g, the minimum quantity of said clinker by weight percent being determined using formula (I) for a clinker having a Dv97 varying between 10 and 30 μm or using formula (II) for a clinker having a Blaine specific surface area greater than or equal to 5300 cm
    2 /g, i.e. [26 x ln(Dv97
    k )] - 43 (Formula (I)), wherein Dv97
    k is the Dv97 of the clinker expressed in μm, and [-6.10
    -3 X SSB
    k ] + 75 (Formula (II)), wherein SSB
    k is the Blaine specific surface area of the clinker expressed in cm
    2 /g; - slag, the minimum quantity of said slag by weight percent being determined using formula (III) in the case of a mix with a clinker having a Dv97 varying between 10 and 30 μm or using formula (IV) in the case of a mix with a clinker having a Blaine specific surface area greater than or equal to 5300 cm
    2 /g, i.e. [1000 ÷ SSB
    L ] x [(-90 x ln(Dv97
    k )) + 310] (Formula (III)), wherein Dv97
    k is the Dv97 of the clinker expressed in μm and SSB
    L is the Blaine specific surface area of the slag expressed in cm
    2 /g, and [1000 + SSB
    L ] x [(0.021 x SSB
    k ) - 103] (Formula (IV)), wherein SSB
    k and SSB
    L are respectively the Blaine specific surface area of the clinker and the slag expressed in cm
    2 /g; the total clinker quantity in the binder pre-mix being strictly lower than 60 %. The invention also relates to a dry binder pre-mix obtained by mixing said dry binder pre-mix with aggregates, as well as to a wet concrete obtained by means of mixing with water.
