    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 fire rated door includes a core, a first decorative panel and a second decorative panel. The core includes: (a) a fire resistant center panel having a bottom, a top, a first side, a second side, a first end and a second end, wherein the fire resistant center panel is made of a first fire resistant material, and (b) an extruded fire resistant border attached to the first side, the second side, the first end and the second end of the fire resistant center panel, wherein the extruded fire resistant border is made of a second fire resistant material having a higher density than the first fire resistant material. The first decorative panel is attached to the top of the fire resistant center panel and the extruded fire resistant border. The second decorative panel is attached to the bottom of the fire resistant center panel and the extruded fire resistant border.
