Abstract

The peculiarities of mineral morphology of oxychloride cement obtained from the dolomite
burning adding intensifiers are considered. It’s revealed that periclase and calcite are
formed as fine-crystalline, periclase has a distorted lattice. It’s suggested that these peculiarities
of the morphology provide the oxychloride cement from dolomite with strength that is
similar to the strength of binding substances made of magnesite and brucite.
