| A cement composition for a self-levelling concrete, includes a mixture of rheology-modifying additives, 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 the concrete in the fluid state, selected from a non-hydrophobically-modified hydroxyalkylcellulose having a degree of polymerization 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. | ||||||

| Compositions and methods for manufacturing sheets having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more inorganic aggregate materials, fibers, and optional admixtures in the correct proportions in order to form a sheet which has the desired performance criteria. The inorganically filled mixtures are formed into sheets by first extruding the mixtures and the passing the extruded materials between a set of rollers. The rolled sheets are dried in an accelerated manner to form a substantially hardened sheet, such as by heated rollers and/or a drying chamber. The inorganically filled sheets may have properties substantially similar to sheets presently made from traditional materials like paper, cardboard, polystyrene, plastic, or metal. Such sheets can be rolled, pressed, scored, perforated, folded, and glued. They have especial utility in the mass production of containers, particularly food and beverage containers. | ||||||
