摘要: THE hardening process by which a cement is formed from polycrystalline matrix has been investigated using of relatively simple composition and structure—Sorel cement1. This the addition magnesium chloride solution to fine powder oxide2. The viscous paste hardens on drying sets consisting mass needle-like crystals Mg3(OH)2Cl.4H2O. appearance shown in Fig. 1, was taken with scanning electron microscope (by A. Rezanowich I.
