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. A particle including a substrate comprising a plurality of crystalline needle or rod-shaped structures of an ettringite mineral attached radially to a surface of the substrate, wherein the substrate includes one of an approximately spherical shape, a rod, a ring or a platelet.

具有晶体针状或棒状结构的微粒，例如从其表面径向生长和附着的钙矾石矿物。 描述了在钙，硫和铝的溶液（例如磺铝酸钙，石灰和硫酸钙）存在下从颗粒表面成核和生长结晶针/棒的方法。 一个例子是在基于硫铝酸钙的水泥浆和混凝土中的飞灰颗粒表面上的钙矾石针的径向生长。 一种包含基材的颗粒，该基材包含多个沿着基材表面径向附着的钙矾石矿物的结晶针状或棒状结构，其中所述基材包括大致球形，棒状，环状或血小板中的一种。
