RISTreatment of Landfill Nanofiltration Concentrated Leachate by Flocculation Combined with a Multistage Ozone/Bioreactor Based on a Field Scale
Publisher: ASCE
Abstract: Nanofiltration concentrated leachate (NFCL) is a high-concentration organic wastewater produced from landfill leachate during the process of membrane advanced treatment, which is more difficult to treat than landfill ...
Impact of Elevated Temperatures on the Performance of High-Strength Engineered Cementitious Composite
Publisher: ASCE
Abstract: Engineered cementitious composite (ECC) is a relatively recent construction material with characteristics of high ductility and energy dissipation capacity. Such ductility is fulfilled by adding polymeric fibers, such as ...
Experimental Investigation on Reservoir Sediment Flushing through a Bottom Tunnel with an Initially Covered Intake
Publisher: ASCE
Abstract: Reservoir sedimentation is of worldwide concern, involving not only reservoir benefits, but environmental and ecological issues. Sediment flushing is one of the most common and effective methods for alleviating sedimentation ...
Performance of Concrete Placing in Hong Kong Buildings
Publisher: American Society of Civil Engineers
Abstract: A study was made in the early 1990s of the utilization of labor and equipment resources in the in situ concreting of buildings in Hong Kong. The study involved close observation of 154 pours on building construction sites ...
Properties of Polyvinyl Alcohol-Steel Hybrid Fiber-Reinforced Composite with High-Strength Cement Matrix
Publisher: American Society of Civil Engineers
Abstract: Mechanical properties of polyvinyl alcohol–steel hybrid fiber–reinforced engineered cementitious composite (ECC) with a high-strength cement matrix are experimentally investigated in this paper. Effects of additional steel ...
A Multifield Model for Early-Age Massive Concrete Structures: Hydration, Damage, and Creep
Publisher: ASCE
Abstract: A multifield model of the early-age behavior of massive concrete structures is presented. The hydration process and the thermal evolution are both described through a coupled chemo-thermal model that predicts the degree ...
Optimizing a High-Speed Railway Operation Plan Based on Train Capacity and Service Frequency
Publisher: ASCE
Abstract: In this paper, a model to optimize a high-speed railway operation plan by dividing it into a train route plan and train stop schedule plan was developed based on the train capacity and service frequency. To capture the ...
Investigation on the Distribution Characteristics of Partial Carbonation Zone of Concrete
Publisher: ASCE
Abstract: This paper aims to investigate the distribution characteristics of the partial carbonation zone of concrete. A series of experimental carbonation tests considering the effect of external temperature, concentration of CO2, ...
Study of Self-Cleaning and Anticorrosion Superhydrophobic Coating on Cement Mortar Using Milled Coral Waste Powder
Publisher: ASCE
Abstract: To reduce and reuse waste, the use of coral waste has attracted more and more attention from researchers. In this study, a method of preparing environmentally friendly superhydrophobic coating with coral waste and stearic ...
