Natural fluorapatite as a raw material for Portland clinker

Cement and Concrete Research, 2018
Abstract The present work focuses on the mineralogy and the reactivity of clinkers made from the integration of natural fluorapatite in the raw meals with percentages ranging from 0 up to15%. The samples were characterized by infrared spectrometry, X-ray diffraction and microscopy techniques. The distribution of phosphorous and fluorine into clinkers

Waste fuels: their effect on Portland cement clinker

Cement and Concrete Research, 2005
Abstract Nowadays, different kinds of industrial wastes are increasingly used in the clinkering process by the cement industry, with the aim of taking advantage of their energy content or confining unsuitable substances. This work evaluates the physicochemical characteristics of the clinkers obtained after incorporating three different wastes in ...

Microwave clinkering of ordinary and colored portland cements

Cement and Concrete Research, 1996
Abstract Regular and colored cement clinkers were prepared by microwave processing at 2.45 GHz. Microwave enhancement in clinker reaction was observed. The preliminary results show that microwave processing can lower the clinkering temperature by about 100 °C compared to the samples processed in a fast-heating electric furnace.

Alkali compounds in Nigerian portland cement clinkers

Cement and Concrete Research, 1983
Abstract Four out of the six Nigerian Portland cement clinkers contain alkali bearing compounds in the form of either single or double sulphates. An attempt has been made to identify these compounds and derive their compositions from SEM-EDXA study.

Mechanism of glass formation in portland cement clinker

Cement and Concrete Research, 1979
Abstract In the system C 3 AC 4 AFSiO 2 MgO, the glass formation region that is closely similar in composition to the interstitial material of portland cement clinker has been determined. The interstitial melt that exists in equilibrium with the silicates at the clinkering temperature contains a little silica.
