Effects of cement flue dust from a cement factory on stress parameters and diversity of aquatic plants.
Abstract Cement kiln dusts, made of a complex mixture of elements, include high levels of heavy metals such as fluoride, magnesium, lead, cadmium, nickel, zinc, copper, beryllium and some toxic compounds. Because of the toxic element compositions and radioactive isotope properties of cement kiln dusts, not only terrestrial but also aquatic ecosystems are subjected to […]

Site preferences of fluoride guest ions in the calcium silicate phases of Portland cement from 29Si{19F} CP-REDOR NMR spectroscopy.
Abstract A reduction in CO(2) emission from Portland cement production can be achieved by energy savings associated with a lowering of the temperature at which the high temperature alite (Ca(3)SiO(5)) and belite (Ca(2)SiO(4)) silicates form. This can be accomplished by fluoride mineralization where a small amount of fluorine (e.g., CaF(2)) is added to the raw […]

Determination of fluoride in cement and related materials
Abstract This paper describes the determination of fluoride in cement and cement-related materials using a fluoride ion selective electrode. Different sample preparation methods and complexing buffers were investigated. It was concluded that the fluoride electrode offers a rapid and accurate method for fluoride determination in cement and cement-related materials when a suitable buffer medium capable […]

FLUORINE BALANCE AND FLUORINE EMISSION FROM CEMENT KILNS
IN THE BURINING OF PORTLAND CEMENT CLINKER THE FLUORINE IS PARTLY DRIVEN OUT OF THE RAW MATERIAL AND FUEL. IN ORDER TO ELUCIDATE THE QUESTION WHETHER THE FLUORINE IS EMITTED IN GASEOUS FORM WITH THE KILN EXIT GASES OR IS COMBINED IN SOLID FORM IN THE CLINKER OR IN THE DUST, COMPLETE FLUORINE BALANCES FOR […]
