RISNumerical Simulation of Wind Fields at the Bridge Site in Mountain-Gorge Terrain Considering an Updated Curved Boundary Transition Section
Publisher: American Society of Civil Engineers
Abstract: To investigate the characteristics of wind fields at the bridge site in mountain-gorge terrains more accurately and rationally, an updated curved boundary transition section (BTS) was proposed in this study. The flow ...
Effect of Synthesized Fe(OH)3 in Aluminum Sulfate Alkali-Free Liquid Accelerator on the Properties of Portland Cement
Publisher: American Society of Civil Engineers
Abstract: Aluminum sulfate alkali-free liquid accelerators are shotcrete admixtures used in the construction of tunnels and culverts. However, the hydration rate of ordinary portland cement (OPC) with aluminum sulfate alkali-free ...
Dosage Control of the Fenton Process for Color Removal of Textile Wastewater Applying ORP Monitoring and Artificial Neural Networks
Publisher: American Society of Civil Engineers
Abstract: Textile wastewater containing a high level of color and refractory chemical oxidation demand (COD) is difficult to treat using traditional wastewater treatment processes. Typically, a chemical process was suggested as a ...
Effect of Synthetic Ettringite on the Hydration of Sulfoaluminate Cement-Based Grouting Materials
Publisher: ASCE
Abstract: Ultrafine ettringite (UE) can accelerate the hydration of sulfoaluminate cement-based grouting materials (SCGMs). However, the mechanism of UE on the hydration of SCGM is not clear. Many researchers believe that ultrafine ...
