RISSimulating the Long-Term Performance of Multifunctional Green-Pervious Concrete Pavement in Stormwater Runoff–Induced PAHs Remediation
Publisher: ASCE
Abstract: Stormwater runoff–induced polycyclic aromatic hydrocarbons (PAHs) increasingly raise concerns about groundwater quality and safety. Among stormwater management infrastructures and facilities, pavement plays an important ...
Hydration of Portland Cement Pastes Containing Untreated and Treated Hemp Powders
Publisher: ASCE
Abstract: In this study, the residual of hemp products as biomass wastes has been ground into powders to be used in cement-based materials. The effect of untreated and alkaline-treated hemp powders on the hydration of portland cement ...
Raman Spectroscopy Study on the Hydration Behaviors of Portland Cement Pastes during Setting
Publisher: American Society of Civil Engineers
Abstract: In the research reported in this paper, an in-situ observation on the hydration of cement pastes with various water-to-cement (
A Vibration Absorption Method for Alleviating Impact of the Flexible Robotic Arm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Impact may excite intense vibration responses of the flexible robotic arm and thus deteriorate its working performance. A vibration absorption method is put forward to alleviate impact influence of the flexible robotic ...
Prediction of Early Age Normal Concrete Compressive Strength Based on Dynamic Shear Modulus Measurements
Publisher: American Society of Civil Engineers
Abstract: In this research, the relationship between the compressive strength,
Phase Change of Carbon Atoms in Surface Layer Under Nanocutting During Diamond Lapping Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lapping is still an efficient and economical way in diamond shaping process, which is important in both industrial and scientific applications. It has been known that the material removal originates from the phase change ...
Sulfate Attack Induced Dry–Wet Failure Modes and a Constitutive Model for Mortar Specimens with a Single Intermittent Fracture
Publisher: ASCE
Abstract: Cracks will be introduced into mortar specimens and embedded copper sheets to simulate fractured concrete according to the designed 20 mm crack lengths and angles. By taking into consideration the actual environment of a ...
Signal Processing for Operational Modal Analysis of a Jacket-Type Offshore Platform: Sea Test Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Operational modal analysis (OMA) has been widely used for large structures. However, measured signals are inevitably contaminated with noise and may not be clean enough for identifying the modal parameters with proper ...
Optimal Bid Model for Price-Time Biparameter Construction Contracts
Publisher: American Society of Civil Engineers
Abstract: Construction clients are increasingly calling for bids that require competing contractors to submit both the bid price and contract time. In such situations contractors are faced with the problem of deciding which combination ...
Techno-Economic Assessment of Enamel Heat Pipe Exchanger in a Combined Heat and Power Plant With Back Pressure Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The enamel heat pipe exchanger (EHPE) is a promising technology for waste heat recovery of coal-fired flue gas due to its abilities to resist acid corrosion, erosive wear, and ash deposit. This article presents a techno-economic ...
