Trace Elements in Clinker –
The trace element content of clinkers (and possibly of cements) can be used for the qualitative identification (i.e. manufacturing factory). Several hundred clinker sorts have been analysed (by replicated quarterly samples, collected from all Hungarian cement factories as well as from factories of 8 foreign countries) to determine their Mg, Sr, Ba, Mn, Ti, Zr, Zn and V content. The first 6 elem...
متن کاملReusing Desulfurization Slag in Cement Clinker Production and the Influence on the Formation of Clinker Phases
The purpose of this study was to investigate the reuse of desulfurization slag in cement clinker production and its influence on the formation of clinker phases. The desulfurization slag that mainly contained Ca and Si was identified as non-toxic, and thus it should be suitable to be reused in clinker production. The addition of desulfurization slag increased the melt phase during clinkerizatio...
متن کاملHydration, hydration, hydration.
Throughout the world, large numbers of manual workers perform physically demanding labour in conditions of high environmental heat stress. Although the importance of adequate hydration in combating heat stress is universally recognized, studies in a range of worker groups have demonstrated a disturbingly poor hydration level in a high proportion of at-risk workers. Management of work in hot env...
متن کاملProtective Effect of Forced Hydration with Isotonic Saline, Potassium Chloride and Magnesium Sulfate on Cisplatin Nephrotoxicity: An Initial Evaluation
Background: Nephrotoxicity is one of the major side-effects of cisplatin that has been seen in about 20% of treated patients. The aim of this study was to assess the effectiveness of a forced hydration protocol comprised of isotonic saline, potassium chloride (KCl) and magnesium sulfate (MgSO4) on prevention of cisplatin nephrotoxicity. Methods: This cross sectional prospective study was perfor...
متن کاملCalculation of the C3A Percentage in High Sulfur Clinker
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 composi...
