摘要： A plurality of non-white roofing granules is provided. The roofing granules include a plurality of particles including mineral fines and a calcia-based cement binder; and a non-white pigment-containing coating disposed on at least a portion of exterior surfaces of the particles. Methods of making the roofing granules are also provided. One method includes: mixing material including mineral fines and a calcia-based cement binder to provide agglomerates; curing the agglomerates to provide particles; and coating at least a portion of exterior surfaces of the particles with a non-white pigment-containing coating. Another method of making the roofing granules includes: providing an aqueous dispersion in a tool having cavities, the aqueous dispersion including mineral fines and a calcia-based cement binder; curing the aqueous dispersion in the tool to provide particles; and coating at least a portion of exterior surfaces of the particles with a non-white pigment-containing coating. The roofing granules exhibit an intrinsic total solar reflectance greater than 0.3. Often, the roofing granules contain by-product mineral fines.

摘要： A method of making a porous metal matrix composite is provided. The method includes mixing a metal powder, a plurality of inorganic particles, and a plurality of discontinuous fibers to form a mixture, wherein the metal powder comprises aluminum, magnesium, an aluminum alloy, or a magnesium alloy. The method further includes sintering the mixture to form the porous metal matrix composite. Typically, the inorganic particles comprise porous particles or ceramic bubbles or glass bubbles, and the inorganic particles and the discontinuous fibers are dispersed in the metal. The metal matrix composite has a lower density than the metal and an acceptable yield strength.
