Calculation of the C3A Percentage in High Sulfur Clinker
نویسندگان
چکیده
The aim of this paper is to clarify the influence of the clinker SO(3) on the amount of C(3)A. The calculation of the cement phases percentages is based on the research work, Calculation of the Compounds in Portland Cement, published by Bogue in 1929 .The usage of high sulphur fuels, industrial wastes, and tires changes completely the working condition of Bogue because the assumed phase compositions may change. The results prove that increasing the amount of SO(3) in the low alkali clinker decreases the percentages of C(3)A due to the high incorporation of alumina in the clinker phases mainly C(2)S and C(3)S. The correlation is linear till the clinker SO(3) reaches the 2%. Over that the influence of the clinker SO(3) became undetectable. A new calculation method for the determination of the C(3)A in the high sulphur and low alkali clinker was proposed.

Portland cement could be produced by heating the raw materials (clay, lime stone) about 1500°C which clinker will be formed. The geochemistry and mineralogical studies of raw materials, clinker, Portland cement and dust have been carried out by optical microscopy, X-ray diffraction and X-ray florescence. The results of spectrometry indicate the presence of calcite mineral in limestone, montmori...

Abstract: The linear expansion, early-age compressive strength and setting times of the binary mixtures of gypsum and Portland cement clinkers of relatively low C3A-contents were investigated. For this reason, type 1, 2, and 5 of Portland cement-clinkers were selected and a number of binary mixtures were designed. At relatively lower percentages of gypsum (about 5%), the early strength behavior...
متن کاملSimulation of Cement Grinding Process for Optimal Control of SO3 Content
Cement is produced by co-grinding clinker, gypsum and other components defined in the Cement Standards like limestone, pozzolans, fly ash and slag. The grinding is usually performed in horizontal ball mills. Gypsum is typically the basic source of sulphates (SO3) in the cement. The effect of gypsum on the cement quality is critical and twofold. It affects two of the main properties of this prod...

In the present work the internal sulfate attack on pastes made from pure clinker phases was studied. Two binders were produced: (a) a binder with 2% C3A and 18% C4AF content; (b) a binder with 10% C3A and C4AF content each. Gypsum was used as the sulfate bearing compound, while calcium carbonate added to differentiate the binders produced. The phases formed were identified by XRD analysis. The ...
