摘要：The self-leveling fluid screed cement composition with limited shrinkage,formed by a mixture of a cement binder, a fluidizing adjuvant, granulates and water, ischaracterized in that the binder includes 70% to 85% by weight of Portland cement, 7%to 18% by weight of sulfo-aluminous clinker, and 6% to 14% by weight of calcium sulfate,with a calcium sulfate C$/calcium sulfo-aluminate CA$ molar ratio of between 5 and 7 anda water/binder ratio by weight of between 0.60 and 0.90. The self-leveling fluid screedthat is thus produced has a mechanical resistance to its compression at 24 hours that is atleast equal to 1 MPa, shrinkage at 7 days, measured under a relative hygrometry of 50%,less than 500 μm/m, and an endogenic expansion value that is measured at 7 days, lessthan 1,000 μm/m, as well as a very slight lifting of edges.
