·Ltd ; Desulfurization gypsum Huainan Thermal Power Plant The content of hemihydrate gypsum and dihydrate gypsum are % and % respectively Meanwhile the chemical composition and phase XRD spectrum of the desulfurized gypsum are shown in Table 1 and Fig 1 respectively; the TG DSC analysis curve is shown in Fig 2;
·Application performance advantages of polycarboxylic acid water reducer in desulfurized gypsum Dispersibility In desulfurized gypsum the dosage of different types of water reducers varies
·The ultra high addition of 20 % desulfurized gypsum is beneficial to improve the strength of DG based binary cementitious materials with low energy consumption Compared with silicate cement geopolymer has the advantages of large raw material reserves low energy consumption and almost no consumption of limestone resources which is an
·The effective and safe use of FGD gypsum in agricultural land is still debated in some countries even though its effectiveness in soil management has been reported in many studies Thus the changes in the levels of soil salinity alkalinity crop yield and other physicochemical properties in different soil types and crops after reclamation and planting with
·Desulfurized gypsum DG presents significant challenges in recycling with the rapid development of industrialization To explore the feasibility of DG as a sulfate source in producing limestone calcined clay cement LC3 this study investigates the differences between LC3 samples containing DG and those containing natural gypsum NG in terms of hydration
·The advantage of CDEM over conventional finite element or discrete element software is its ability to well describe the elastic deformation and plastic deformation of soft rock "Development and Application of Flue Gas Desulfurized Gypsum and Blast Furnace Slag Based Grouting Material for Cracked Silty Mudstone" Materials 17 no 23 5975
·The modified CDA is converted from calcium sulfite to calcium sulfate which can replace natural gypsum in construction materials and greatly save natural gypsum resources Wansom et al replaced natural gypsum in the cement industry by modified CDA from power plant in Thailand It was found that the disadvantages of unmodified CDA for
·This work aimed to investigate the feasibility of utilizing the low quality desulfurization ash from semi dry flue gas desulfurization by mixing with α hemihydrate gypsum and then the environmental issues resulted from low quality desulfurized ash from semi dry flue gas desulfurization can be resolved and both economic and ecological benefits are brought to
