Steel slag powder (SS), ground granulated blast-furnace (GGBS), and flue gas desulfurization gypsum (FDG) are environmentally friendly cost-effective substitute materials for ordinary Portland cement (OPC). This study investigated the use of industrial solid wastes, including SS, GGBS, FDG, as auxiliary in OPC to stabilize pretreated recycled concrete aggregate (pretreated RCA). The RCA, mixed cementitious materials, water at optimum content created a mixture designated cement-stabilized...
Abstract Reactive powder concrete (RPC) is a novel high-performance building material widely used in large-scale engineering structures due to its superior mechanical properties and durability. However, structural failure can still occur under dynamic load impacts. Therefore, optimizing the impact resistance of RPC remains critical issue for enhancing applications. In this study, were investigated by adjusting water-cement ratio incorporating supplementary cementitious materials (SCMs), such...
Abstract The calcium sulfate hemihydrate whiskers were prepared from phosphogypsum at hydrothermal condition. influences of different organic acid (citric and poly (acrylic acid)) on the crystal morphology detected, respectively. crystals can be influenced by adding acid. Short large columnar obtained 5 wt.% citric acid, which used as cementitious materials. long with uniform diameter acid), applied in composites.
The influences of organic compounds, supernatant, calcium phosphate and fluoride on the morphology sulfate hemihydrate were investigated in hydrothermal conditions by using sulphate dihydrate analytical grade as raw material, while compounds supernatant obtained from phosphogypsum (PG).The influence crystal growth was greater than compounds.The diameter increased aspect ratio decreased, added amounts increased.The more obvious with fluoride.Extremely non-uniform whiskers observed when amount...
In this article, a platform for measuring moisture content in coal is developed; measurement carried out on frequency within 6.6–9.9 GHz. As result, the fitting curve of microwave attenuation and are acquired. When wavelength at least five times that particle size, which indicates λ/d ≥ 5, result will be more accurate. Further, there quadratic curvilinear correlation between attenuation.
Mullite fibres were prepared using aluminium carboxylates (ACs) and tetraethylorthosilicate by sol–gel process. ACs synthesised from dissolution in a mixture of formic acid glacial acetic chloride hexahydrate as catalyst. The optimum condition for obtaining is follows: the molar ratio aluminium, was 1∶3∶2·26 10 wt-%. All Al Si components mixed at molecular level linear molecules formed precursor sol. dried gel completely transformed to mullite 1200°C calcinated had smooth surface uniform diameter.
AbstractLong fibres of mullite were prepared by sol–gel method using aluminium nitrate, malic acid and tetraethylorthosilicate (TEOS). Thermogravimetry/differential scanning calorimetry (TG/DSC), Fourier transform infrared (FTIR) spectra, X‐ray diffraction (XRD), electron microscopy (SEM) analyses used to characterise the properties gel ceramic fibres. The completely transformed at 1200°C, with a uniform diameter dense microstructure.
a-hemihydrate gypsum is synthesized from phosphogypsum and the influence of a CaO treatment, solution pH maleic acid addition on microstructure have been systematically investigated.The resolvable phosphorous hemihydrates can be reduced by treatment.The mid-diameter columnar crystals decreases crystal surface becomes smooth with decrease.Moreover, changed growth direction equiaxed a-hemihydrates were obtained in pH=2 solution.Furthermore, effect different additives, such as Portland cement...
