A significant amount of waste is generated during the sandstone mining process. This study explores use red as a supplementary cementitious material to address environmental concerns in cement production. The experimental methods include isothermal calorimetry, compressive strength testing, thermogravimetric analysis, X-ray diffraction, infrared spectroscopy, scanning electron microscopy, high-temperature damage testing (200, 600, and 900 °C), mesoscopic image analysis. findings reveal...
In recent years, deep learning-based detection methods have been applied to pavement crack detection. practical applications, surface cracks are divided into inner and edge regions for pavements with rough surfaces complex environments. This creates difficulties in the image task. paper is inspired by U-Net semantic segmentation network holistically nested network. A side-output part added decoder that performs extraction supervision. model combining two tasks can output results of different...
Nano silica (NS) has been found to have a positive impact on enhancing the microporous structure of Ultra-High-Performance Concrete (UHPC). However, there is lack effective methods accurately characterize regulatory improvement mechanism NS pore UHPC. In this study, our objective investigate influence various characteristic parameters in UHPC, including porosity, average size, box fractal dimension, and multifractal spectral parameters. To analyze these effects, we employ combination X- CT...
Graphene oxide/cement composite was prepared using a graphene oxide aqueous solution. The workability and mechanical properties of with different concentrations for the ratio water to cement were investigated. results observed fluidity pastes decreased noticeably addition increased increase in all tested samples contents. It is indicated that noticeable inverse correlation between concentration observed, positive linear relationship also obtained. compressive strength significantly improved...
A cement-based piezoelectric composite, modified by graphene oxide (GO), was prepared to study piezoresistive capacity. The testing confirms that GO is more effective than other carbon nanomaterials at improving sensitivity of composites, because the content in cement paste much lower used previously published research. Further investigation indicates addition significantly improved stability and repeatability for capacity under cycle loads. Based on experiment results, this composite...
Due to the low content of silicon and aluminum in red mud reaction activity mud, when it was used prepare composite cementitious materials, necessary assist other aluminosilicates improve their by certain methods. In this study, proposed add slag increase percentage system, reactivity system through activation effect sulfate phosphogypsum. The effects phosphogypsum contents on mechanical properties microstructures materials were studied. X-ray diffraction analysis (XRD), thermogravimetric...
Taking advantage of the strong adsorption characteristics coffee grounds (CGs) and ground biochar (CGB), this research employed equal amounts 2%, 4%, 6%, 8% CGs CGB to replace cement. This study thereby examined impacts on cement compressive strength, as well their abilities adsorb chloride ions formaldehyde. X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TG−DTG), scanning electron microscopy (SEM), X−ray photoelectron (XPS) were...
