    摘要: An extrudable cement-based material formed from a mixture that includes cement, water, gypsum, secondary materials, reinforcement fibers and rheology modifying agent. The extrudable cement-based material is a lightweight material that has a density in the range of about 1.4 to 2.4 g/cm3, a compressive strength in the range of about 5 to 100 MPa, and a flexural strength in the range of about 5 to 35 MPa. Note that the cement may contain gypsum such that the gypsum is not added to the mixture.

    摘要: A cement-based tile formed from a mixture comprising: a cement in the range of about 0.1 to 88% by wet weight percent; a secondary material in the range of about 0.1 to 50% by wet weight percent, the secondary material comprising limestone, sand, silica sand, gypsum, silica fume, fumed silica, Plaster of Paris, calcium carbonate, fly ash, slag, rock, or a combination thereof; a reinforcement fiber in the range of about 0.5 to 20% by wet weight percent, the reinforcement fiber comprising cellulose fiber, glass fiber, plastic fiber, polypropylene fiber, polyvinyl alcohol (PVA) fiber, homopolymer acrylic fiber, alkali-resistant fiber, or a combination thereof; a rheology modifying agent in the range of about 0.5 to 10% by wet weight percent; a water in the range of 10 to 60% of a total wet material weight; and wherein the mixture is extruded or molded to form the cement-based tile.
