“…Both the Blaine fineness and the PSD results were compared to a commercially-produced Type I/II Portland cement (TXI Hunter). 24 Both tests were carried out to ensure uniform particle fineness and distribution between each sample.…”

“…This is because of the high amount of gypsum present in the CSA-1 indicating that the reaction for crystal formation (ettringite and gypsum) is faster. 16,24 In addition, the presence of gypsum in CSA-1 cement plays the role of activator for ettringite precipitation, which is responsible for setting and hardening observed. However, in the presence of a low amount of gypsum (in the case of RMC-1), the hardening of paste will be delayed, leading up to more porosity and strength reduction resulting in a long setting time observed.…”

“…21 Considering their high availability, some works done by Tchamba et al 22 and have shown that Cameroonian bauxite and limestone are suitable for the production of Portland clinker, geopolymers binders, and refractory bricks for furnaces. 23 On the other hand, in the tropical zone, these materials (bauxite, clay, and limestone) are available and abundant and represent the largest fraction of raw materials used to produce CSA cement (Canbek and Erdog 2020).…”

This work discusses the effect of rich alumina bauxite on the mineralogical composition of calcium sulfoaluminate (CSA) clinker cement on their performances. After preparation of different local raw materials (rich alumina bauxite and marble), they were mixed with 15 wt% of commercial gypsum and pressed at 2 MPa. The obtained pellets were thermally treated at 1200°C to produce clinker, which is use to synthesize the CSA cements. The raw materials as well as products were characterized by many analyses, such as FT‐IR, X‐ray fluorescence, X‐ray diffraction, differential scanning calorimetry (DSC)/thermogravimetry analysis (TGA), isothermal calorimetry (ICC), scanning electron microscope, and physico‐mechanical tests. ICC analysis of the powder of clinker cement showed that the reactions are strongly affected by gypsum content. XRD results revealed that clinker and cement present a strong intensity of ye'elimite as main mineral phase. Moreover, the hydrated cement exhibited ettringite and monosulfate as the new phases formed. The compressive strength of hydrated cement reached ∼21 and 28 MPa after 1 and 28 days of curing, respectively. From the aforementioned results, this local rich alumina bauxite can be used to produce high‐strength cement for self‐leveling materials, which allow their use in engineering and building applications.

“…The coal quality also affects the quality of industrial products. For instance, the cement clinker product is affected by the temperature generated by coal combustion inside the kiln (Canbek and Erdoğan, 2020;Yang et al, 2021). Therefore, reducing the coal moisture content increases the coal quality to increase efficiency, heating rate, heating value, and industrial product quality.…”

High moisture content in low-range coal causes low calorific value. To increase the quality, drying by a coal dryer to minimize moisture content is proposed. Here, a case study of a cyclone-like conical tube coal dryer pilot plant was reported. Drying heating uses combustion heat generated from volatile matter combustion. This approach will solve the two problems simultaneously: decreasing moisture content and volatile matter. The computational fluid dynamic (CFD) approach is used to study fluid dynamics inside the coal dryer using ANSYS Fluent 2020R2 software. The CFD simulation results represent the phenomenon of coal drying inside the coal dryer validated by the pilot plant experimental result. The simulation was carried out in steady and unsteady conditions to understand the drying phenomena. The simulation firmly fits the experimental result, especially in an unsteady state system, indicating that the simulation result is promising for further coal dryer design. The optimal condition produces a high moisture content reduction of 86.37%, uniform fluid distribution, and significant volatile matter combustion

“…Calcium sulfoaluminate cement (CSAC), which has been manufactured and used on a large scale in China since the 1970s, is considered environment-friendly with low CO 2 emissions [ 1 , 2 , 3 , 4 ]. Compared with Portland cement, CSAC exhibits a shorter setting time, faster hardening, higher early strength, better durability, etc., and is widely used in various special areas of engineering, such as rapid repair engineering, ocean engineering, winter construction and so on [ 5 , 6 ].…”

Effect of Flue Gas Desulfurization Gypsum on the Properties of Calcium Sulfoaluminate Cement Blended with Ground Granulated Blast Furnace Slag

This work aims to investigate the effect of additional flue gas desulfurization gypsum (FGDG) on the properties of calcium sulfoaluminate cement (CSAC) blended with ground granulated blast furnace slag (GGBFS). The hydration rate, setting time, mechanical strength, pore structure and hydration products of the CSAC-GGBFS mixture containing FGDG were investigated systematically. The results show that the addition of FGDG promotes the hydration of the CSAC-GGBFS mixture and improves its mechanical strength; however, the FGDG content should not exceed 6%.
