摘要： 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.

摘要： The invention relates to a cement composition for a self-levelling concrete, that comprises a mixture of rheology-modifying additives, characterised in that it comprises the combination of at least a first agent for substantially increasing the shear threshold of the concrete in the fluid state, selected from a natural polysaccharide ether, a hydroxyalkyl guar ether, a hydroxyethylcellulose or a hydroxypropyl guar, which are hydrophobically modified with the introduction of hydrophobic side grafts, and at least a second viscosity-increasing agent for substantially increasing the viscosity of said concrete in the fluid state, selected from a non-hydrophobically-modified hydroxyalkylcellulose having a degree of polymerisation between approximately 500 and approximately 4500 and a viscosity of less than 50 PA.s in aqueous solution at 2 wt.-% and a poly (ethylene oxide), in order to limit or prevent the dynamic segregation of granulates in the concrete during the implementation thereof. The use of such a composition can replace the presence of a filler in the concrete, in particular a self-levelling concrete, without diminishing the performance concerning the spreading thereof, the sieve stability, the bleeding and the dynamic segregation relative to a concrete containing a filler, in particular a concrete having the same water/cement ratio.
摘要翻译：本发明涉及一种用于自流平混凝土的水泥组合物，其包含流变改性添加剂的混合物，其特征在于，其包含至少第一试剂的组合，用于基本上增加流体状态下混凝土的剪切阈值选自天然多糖醚，羟基烷基瓜尔胶醚，羟乙基纤维素或羟丙基瓜尔胶，其通过引入疏水侧接枝物进行疏水改性;和至少第二增粘剂，用于基本上增加所述混凝土的粘度流体状态选自具有约500至约4500的聚合度和2重量％的水溶液中的粘度小于50PA.s的非疏水改性羟烷基纤维素和聚（环氧乙烷），以限制或防止在实施过程中混凝土中颗粒的动态分离。使用这种组合物可以替代混凝土中的填料，特别是自流平混凝土的存在，而不会降低其相对于含有一种混凝土的混凝土的扩展，筛分稳定性，渗出和动态偏析的性能填料，特别是具有相同水/水泥比的混凝土。
