RISNovel Foam Insulation Material Produced by Calcined Phosphogypsum and H2O2
Publisher: ASCE
Abstract: A novel foam insulation material was prepared using calcined phosphogypsum (CPG) as the raw material and hydrogen peroxide (H2O2) as a foaming agent. Stable foaming of H2O2 in a CPG-based suspension was achieved. The effects ...
Performance Prediction of Gel Water Shutoff in Horizontal Wells Using a Newly Coupled Reservoir–Wellbore Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Water shutoff is a commonly used method to mitigate the early breakthrough in horizontal wells. Gel is frequently used as an effective water shutoff agent in mature fields, especially for horizontal wells in recent years. ...
Stress-Strain Curves of Structural and Reinforcing Steels after Exposure to Elevated Temperatures
Publisher: American Society of Civil Engineers
Abstract: For the evaluation of damage to a structure after exposure to fire, the residual mechanical properties of structural materials need to be evaluated first. Many factors can affect the post-fire behavior of structural and ...
Restrained Torsion of Thin-Walled Beams
Publisher: American Society of Civil Engineers
Abstract: A first-order torsion formulation for closed thin-walled (CTW) beam subjected to restrained torsion is developed to consider the warping deformation and restrained shear stresses on cross section and their effect on the ...
Rheological and Structural Evolution of Rubberized Asphalts under Weathering
Publisher: American Society of Civil Engineers
Abstract: Rubberized asphalt has been widely used for extending the service life of pavement. Understanding the weathering mechanism of rubberized asphalt is useful for selecting appropriate rubberized asphalt. This paper examines ...
3D Discrete Solid-Element Method for Elastoplastic Problems of Continuity
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a novel three-dimensional (3D) discrete solid-element method (DSEM) to calculate the extremely large deformation and high material nonlinearity of continuity. In DSEM, the material is discretized into ...
On-Line Leakage Detection in Buried Tap Water Distribution Pipes Using Distributed Temperature Sensing
Publisher: ASCE
Abstract: The aim of this study was to test the feasibility of the distributed temperature sensing (DTS) method, which is based on Raman scattering, for detecting small leakages of tap water pipes. The temperature drop caused by ...
Enhancement of Bond Performance of FRP Bars with Seawater Coral Aggregate Concrete by Utilizing Ecoefficient Slag-Based Alkali-Activated Materials
Publisher: ASCE
Abstract: To effectively utilize marine resources on reefs or islands and to improve the bearing capacity and serviceability of fiber-reinforced polymer (FRP) reinforced seawater coral aggregate concrete (CAC) structures in marine ...
Winter–Summer Transition in the Southern South China Sea Western Boundary Current
Publisher: American Meteorological Society
Abstract: The winter–summer transition in the southern South China Sea (SCS) western boundary current (WBC) is studied. Two categories have been identified. In case 1, the southern SCS WBC transition in the lower layer (below the ...
Simulated Mid-Holocene and Last Interglacial Climate Using Two Generations of AWI-ESM
Publisher: American Meteorological Society
Abstract: Numerical simulations allow us to gain a comprehensive understanding of the underlying mechanisms of past, present, and future climate changes. The mid-Holocene (MH) and the last interglacial (LIG) were the two most recent ...
