摘要:A method of making Portland cement, white cement, calcium aluminates, calcium aluminum silicates and similar oxides using solid state combustion synthesis is described. The method uses less energy and produces lower CO 2 emissions than conventional processes. The method uses green fuels like biomass and lignin and eliminates most of the coal used in traditional cement production. A batch reactor and a semi-continuous reactor that can be used for the combustion synthesis are also described.

摘要:A method of making cementitious particles using combustion synthesis is described. The method uses less energy and produces lower CO 2 emissions than conventional processes. By controlling the process conditions, the morphology and the properties of the particles can be easily tuned for a variety of applications. A batch reactor and a continuous conveyor type reactor that can be used for the combustion synthesis with high viscosity raw materials are also described.

摘要:Microparticles having crystalline needle or rod-shaped structures of, for example, an ettringite mineral grown and attached radially from their surface. A method including nucleating and growing crystalline needles/rods from the surface of a particle in the presence of a solution of calcium, sulfur, and aluminum such as calcium sulfoaluminate, lime and calcium sulfate is described. One example is the radial growth of ettringite needles on the surface of fly ash particles in calcium sulfoaluminate-based cement paste and concrete.
