In 1956, Paris-based Ciments Lafarge entered the North American cement market by erecting a cement plant in Richmond, British Columbia (BC), near Vancouver and forming Lafarge Cement North America (LCNA). The plant is situated in the westernmost Canadian province of British Columbia, about 10 km south of Vancouver in the community of Richmond. It lies on the north bank of the Fraser River shortly before entering the ...

In the Rohožník plant a “bypass dust washing installation” has been installed to enable full incorporation of the bypass in cements and production of chloride salts that can be commercialized. This ReduDust process transforms the problem of a ...

The cement plant at Rohožník/Slovakia has developed the ReduDust process jointly with plant engineer A TEC, and thus constructed, in the truest sense of the word, it is a green system for removal of chlorine. In this environmentally friendly zero-waste process, the chlorine content of the bypass dust yielded is minimised to such an extent that this dust can subsequently be reused in the process. Industrial salts are the resultant ...

Around 600 participants from twenty-nine countries discussed building materials, their properties, potentials for improvement and ...

In Europe it is generally accepted that more than 65 % of granulated blast-furnace slag (GBFS) in composite cements make them high sulfate resistant. Proven by numerous studies, this rule has been implemented into national standards, such as the ...
