RISUtilization of CO2-Cured Waste Cement Powder to Enhance the Properties and Microstructure of Cement Mortar and Paste
Publisher: ASCE
Abstract: Utilization of waste concrete has been become an urgent requirement for sustainable development due to the huge amounts of construction waste. The most promising strategy is to treat construction wastes by CO2 curing. This ...
Influence of Internal Corrosive Defect on the Burn-Through of In-Service Welding on Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the course of the service of long-distance oil/gas pipelines, due to corrosion, abrasion, and other reasons, the possibility of pipeline leakage is growing. In-service welding is an advanced technique employed in the ...
Study on the Failure Mechanism of Burn-Through During In-Service Welding on Gas Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We conclude on the governing mechanism of burn-through and identify the area of highest risk for burn-through occurrence due to a specific combination of loading in this area. In order to investigate the mechanism of ...
Removal of Azo Dyes Reactive Brilliant Red X-3B by Zero-Valent Iron Enhanced by a Weak Magnetic Field: Efficiency and Mechanism
Publisher: ASCE
Abstract: The removal kinetics and mechanism of azo dye Reactive Brilliant Red X-3B (X-3B) by a weak magnetic field (WMF)–enhanced zero-valent iron (ZVI) were explored. The results show that the reaction rate of zero-valent iron ...
