  • Patent number: 10947158
    Abstract: Devices, systems, and methods of the present disclosure are generally directed to building material including particles of a polymer in an irradiated form, a cement including calcium oxide, and at least one additive including silicon dioxide. In cement paste formed from a mixture of these components, the polymer in the irradiated form may decrease porosity as compared to porosity of cement paste formed without the polymer, and a combination of the silicon dioxide and the calcium oxide may form high-density phases in the cement paste. With these characteristics, such cement paste may exhibit at least the same compressive strength as cement paste formed from the cement by itself. Thus, in certain instances, the particles of the polymer may displace a portion of the cement in a manner that maintains compressive strength while facilitating reduction of greenhouse gas emissions associated with cement paste formation.

  • Publication number: 20090145334
    Abstract: The non-settling refractory mortar of the invention contains 100 parts of ceramic powder such as cordierite, mullite, alumina, or silicon carbide, 0.5 to 1.5 parts of clay mineral, and colloidal oxide solution, in which the Ca content in total solid component is defined at 0.01 to 0.5% as converted to oxide so as to be provided with thixotropic property. As a result, the coating performance is not lowered if stored for a long period after kneading, the dimension change rate after coating is small, and cracks or gaps are not formed on the coat surface. The median diameter of ceramic powder is preferred to be 10 to 50 ?m, and in order to reduce the dimension change rate after coating, the content of particles of 0.1 to 5 ?m in ceramic powder is desired to be 1 to 20%.

  • Patent number: 7351281
    Abstract: Powdered material, the binder phase of which mainly consists of a cement-based system, which powdered material has the capacity following saturation with a liquid reacting with the binder phase to hydrate to a chemically bonded ceramic material, preferably for dental purposes. According to the invention the powdered material has a composition and/or structure suitable for giving the ceramic material translucence in the hydrated state. The invention also relates to the ceramic material produced by hydration of the powdered material.
