    摘要: A composition comprising cement and nano-sized crystalline particles of boehmite alumina or nano-sized crystalline particles of boehmite alumina which have been modified by the inclusion of silicon oxide, calcium oxide, or magnesium oxide. The boehmite alumina has an average crystallite size from about 2 nm to about 80 nm and a content of non-crystalline alumina of less than about 25 mol percent based on total aluminum.
