    Abstract: La composition cimentaire de chape fluide autonivelante à retrait limité, formée d'un mélange d'un liant cimentaire, d'adjuvant fluidifiant, de granulats et d'eau, est caractérisée en ce que le liant comprend de 70 % à 85 % en poids de ciment Portland, de 7 % à 18 % en poids de clinker sulfoalumineux et de 6 % à 14 % en poids de sulfate de calcium, avec un rapport molaire sulfate de calcium C$/sulfoaluminate de calcium C 4 A 3 $ compris entre 5 et 7 et un rapport pondéral eau/liant entre 0,60 et 0,90. La chape fluide autonivelante ainsi réalisée, présente une résistance mécanique à Sa compression à 24 heures au moins égale à 1 MPa, un retrait à 7 jours, mesuré sous une hygrométrie relative de 50 %, inférieur à 500 μm/m et une valeur de gonflement endogène mesurée à 7 jours inférieure à 1000 μm/m, ainsi qu'un très faible relèvement de bords.

    Abstract: The present invention relates to a method of treating marine or river dredging sediments, especially harbour zone sediments, whose free water content is between 40% and 80% by weight, for the purpose of obtaining a solid material which is easy to handle, characterized in that it comprises the following successive steps: - mixing said sediments with a treatment composition comprising a sulphoaluminate binder and at least one other component selected from a sulphate source and a catalyst of the hydration reactions of the sulphoaluminate binder, - a step of setting of said mixture, leading to a compact mixture having a free water content of less than 20% by weight, - then fractionating said compact mixture. The sediment thus treated may be incorporated into concrete or mortar formulas, which then have leachable fractions of less than 1 % by weight.

    Abstract: The invention relates to a cement composition for a self-leveling fluid screed with limited contraction, made of a mixture of a cement binder, a fluidizing admixture, an aggregate and water, characterized in that the binder consists of 70 to 85 wt % of Portland cement, 7 to 18 wt % of sulfoaluminate clinker, and 6 to 14 wt % of calcium sulfate, with a mole ratio of calcium sulfate C$ to calcium sulfoaluminate C4A3$ of between 5 and 7, and a water to binder weight ratio of between 0.60 and 0.90. The self-leveling fluid screed thus produced has a mechanical resistance to compression at 24 hours that is at least equal to 1 MPa, a shrinkage at 7 days, measured under a relative hygrometer of 50%, of less than 500 µm/m, and an endogenous expansion value measured at 7 days of less than 1000 µm/m, as well as very slightly raised edges.
