INFLUENCE OF BARIUM OXIDE ADDITIONS ON PORTLAND CLINKER

barium ions into clinker minerals, the cement prepared from this clinker could shield different types of radiation. Another reason to study the influence of barium on the formation and properties of Portland clinker is the use of alternative fuels and raw materials in manufacturing Portland cement. A small amount of barium leads to changes in the clinker. These alternative materials have ...

Clinker Phases. Portland cement clinker is a "phase assemblage" in which the main mineral crystalline species are: Alite - roughly Ca 3 SiO 5; Belite - roughly Ca 2 SiO 4; Tricalcium Aluminate - roughly Ca 3 Al 2 O 6; Tetracalcium Aluminoferrite - roughly Ca 2 (Al,Fe) 2 O 5; All these chemical formulae are "rough" because the phases are actually solid solutions, and the atoms of the formula ...

Barium incorporated in clinker inhibits formation of alite; therefore, lime saturation factor was slightly reduced. Compared to barium carbonate—another source of barium oxide—barium sulphate influences the ratio of clinker phases less significantly. This clinker and a reference sample without barium were milled with and without addition of gypsum. Hydration of barium clinker and cement ...
