The Influence of SO3 and MgO on Kinetics of Alite Formation

Mineralogy and Geochemistry of Iron Tailings from Yeshan Iron Deposit, Southwest Jiangsu, China: Implications for Potential Utilization

“…A number of recent studies indicate that IOTs can be utilized as industrial raw materials to produce green and sustainable industrial products. − However, the extremely high content of MgO and high content of SO 3 in Yeshan IOTs could bring a huge challenge for using Yeshan IOTs as alternative raw meals to produce cement. It has been confirmed that abundant MgO and SO 3 in raw meals have negative effects on the formation of cement clinker. , Additionally, a large quantity of dolomite and serpentine, and relatively abundant clay minerals exist in Yeshan IOTs, which has adverse effects on the performance of concrete if the Yeshan IOTs replace natural fine aggregates in concrete. Therefore, using Yeshan IOTs sand for full aggregate replacement of natural gravel in cementitious materials could be impractical.…”

Process compatible desulfurization of NSP cement production: A novel strategy for efficient capture of trace SO2 and the industrial trial

“…Generally, about 40-60% of CaSO4, the FGD product, tends to decompose after entering the rotary kiln with hot raw meal (Eq. 11 in Table 5) (Li et al, 2014;Staněk, 2016), and the rest of CaSO4, as well as alkali sulfates, are discharged out of the NSP production process with clinker. Theoretically, CaSO4 can react directly with CaO and Al2O3 at 1250-1300 o C to form 3CaO3Al2O3CaSO4 (Eq.…”

Development of Crystallinity of Triclinic Polymorph of Tricalcium Silicate

“…Therefore, the process of synthesis of clinker minerals is crucial for determination of their subsequent behavior in industrially produced cements. In order to characterize and possibly influence the variability of mineralogical composition of clinkers, the effects of individual polymorphs of clinker minerals on the properties of industrially produced clinkers, especially from the viewpoints of acting chemistry and their internal structures, need to be studied [ 12 , 13 , 14 ]. Generally, about twenty individual minerals can be identified within clinkers, but four of them are the most significant.…”
