  9. Iron oxide has been used in many kinds of industrial applications because it is a rich element on the Earth and a multifunctional material. α-Fe 2 O 3 (hematite) is the most popular material and it is often called "Bengara" or iron oxide red. Bengara has a long history from ancient wall painting [2]. α-Fe 2 O 3 particles are manufactured by various procedures today.

  10. Use of an excess amount of alumina quickens setting time but reduces the strength of cement. 04. Iron Oxide: This is mainly responsible for imparting colour to cement. The hardness and strength is also improved to a certain extent. It helps in the fusion of raw materials during the manufacture of cement.

  14. Biochemistry and physiology. In contrast to zinc, iron is an abundant element on earth[2,9] and is a biologically essential component of every living organism.[10,11] However, despite its geologic abundance, iron is often a growth limiting factor in the environment.[] This apparent paradox is due to the fact that in contact with oxygen iron forms oxides, which are highly insoluble, and …

  15. Magnesium oxide seems to be available, even if the deposits might not be as close to the surface as those currently exploited by the cement industry. Based on calcium, silicon, aluminium and iron, new cements could be foreseen, starting from Portland cement all the way to pure aluminosilicates that certainly contain no lime at all.

  16.  · The cement used in this study is a commercial Portland cement (Lafarge North America Corp.) that satisfies Type I and Type II requirements set forth in ASTM American Society for Testing and Materials (ASTM) C-150 .The properties of Portland cement are presented in Table 1.Four iron oxides (and oxyhydroxides) were used for this study: magnetite, hematite, ferrihydrite, and goethite.
