The dataset presented in this paper comprises compressive strength test results for PO42.5 Portland cement mixed with mine water containing sulfate, magnesium, and bicarbonate ions. tests are designed to systematically assess the impacts of these ions, both individually combination, on long-term mechanical properties cement. Furthermore, X-ray diffraction (XRD) scanning electron microscopy (SEM) analyses were conducted investigate microstructural characteristics cement-based materials under...

Fiberglass porous ceramics were prepared via a foam-gelcasting method. The relationship between the rheology of slurries and structure specimens was investigated. results show that when content dispersant 0.25 wt %, exhibit excellent fluidity. thixotropic behavior strongly influenced by foam stabilizer agent solid content. Furthermore, as fluidity foaming increased, size pores increased. At same time, thickness pore walls decreased gradually. In addition, promoting uniform distribution...

This study was conducted to theoretically analyze the overturning axes of curved box-girder bridges with three equal spans and single-column piers per influence curvature radius bearing eccentricity on axis. The theoretical analysis is verified by a model bridge experiment. results show that axis can be effectively determined according connecting line either bearings at central or outmost abutments as influenced eccentricity. In other words, no are outside All but two located inner side For...

The article studied the changes of active and nutritional ingredients Pinellia Ternata ingested by a pheasant. In process field experiment, it was accidentally found that pheasants liked to feed on P. ternata bulbil. To understand effects pheasant feeding ternata, an experiment designed immediately after feeding. results showed contents alkaloid, β-sitosterol, Phenylalanine ammonia-lyase activity, soluble sugar, free amino acid, protein in aboveground bulbil tubers were significantly...

To eliminate the effects of image’s light and shade difference when separating distinguishing material composition, a method is put forward, namely, ring‐type partitions threshold segmentation. It means setting up different segment for areas same image then combining these into one image. Furthermore, by analyzing CT before after RLWT rutting test drilling specimen Marshall taking volume air voids angle (alpha) between max main axis X axis, differences two kinds specimens’ macrotest results...

This paper introduces the factor of stability against overturning (FSO) for curved bridges, and examines influence curvature radius bearing eccentricity on FSO under self-weight vehicle loads as well other important parameters. The results show that variation rules are indeed affected by eccentricity. Lane identified crucial parameters in resistance bridges. Bearing influences inner side outer reactions abutment bearings, but optimal can ensure uniform torque distribution; said is expressed...

Abstract Carbonate electrolytes have been extensively used as commercial in lithium‐ion batteries (LIBs) because of its high oxidative stability. However, the organic‐inorganic solid electrolyte interphase (SEI) formed on lithium (Li) metal surface is too fragile to endure huge volume fluctuation during Li plating/stripping cycles carbonate electrolytes. Herein, a chemically stable inorganic‐rich SEI was constructed anodes by dissolving 5.5 M LiNO 3 N,N‐dimethylformamide (DMF) into an...

An adaptive fuzzy robust controller is designed to improve the electrode control of three-phase electric arc furnace regulator system. The design process system proposed in detail. impacts tracking error and approximation parameter law are considered. approximate external disturbances compensate controls adopted. simulation results show that this algorithm has good dynamic response stable-control accuracy, a strong robustness for structural uncertainty.

Taking the curved continuous rigid frame bridges (CRFBs) with high piers as research object, construction stability of four different styles main were analyzed by finite element (FE) method in three stages including segment 0 stage, largest cantilever and finished bridge stage. Rules governing stabilities various pier styles, height, slenderness ratio established. At stages, type height affect structural differently. Wind loads have little influence on at any accidental events more than...

On the basis of computational ghost imaging (CGI), we present a new technique, feature (FGI), which can convert color information into distinguishable edge features in retrieved grayscale images. With extracted by different order operators, FGI obtain shape and objects simultaneously single-round detection using one single-pixel detector. The distinction rainbow colors is presented numerical simulations verification FGI's practical performance conducted experiments. Furnishing perspective to...

Ca-based geopolymers are a principal product of introducing calcium into geopolymers. Analyzing structural and mechanical properties aids in optimizing mix design In this paper, partially reacted low-polymerization fully high-polymerization models were constructed to examine the with varying contents via molecular dynamics simulations. Results show that contain pentacoordinate aluminum tricluster oxygen which is more brittle makes structure loose. models, an increase content accelerates...
