RISImpact and Improvement of Crushed Tuff Sand on Sulfate Resistance of Cement Concrete at Low Temperature
Publisher: American Society of Civil Engineers
Abstract: Experimental tests were conducted to study the thaumasite formation of sulfate attack (TSA) erosion resistance of cement concrete made with crushed tuff sand. Different specimens made with either crushed tuff sand or river ...
Influence of Accelerator Dosages on the Viscosity–Time–Temperature Characteristics, Morphology, and Mechanical Properties of Hot Mix Epoxy Asphalt
Publisher: American Society of Civil Engineers
Abstract: AbstractTo address the contradiction between high-temperature construction retention time
and normal-temperature curing time of hot mix epoxy asphalt (HEA), in this paper,
2,4,6–tris (dimethylaminomethyl) phenol (TAP) was ...
Causality of the Drought in the Southwestern United States Based on Observations
Publisher: American Meteorological Society
Abstract: AbstractSlow feature analysis is used to extract driving forces from the monthly mean anomaly time series of the precipitation in the southwestern United States (1895?2015). Four major spectral scales pass the 95% confidence ...
Effect of Laser Parameters on Microstructure and Fracture Properties of Repaired Cracks with Micro/Nano Material Addition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compact tension specimens with prefabricated cracks are repaired by laser with micro/nano materials added at the crack tip. Different combinations of laser parameters, i.e., laser power, laser spot diameter and heating ...
Performance-Based Mix Design of Epoxy-Modified Fully Recycled Asphalt Mixture and Feasibility of Its Application in the Middle Surface Layer
Publisher: American Society of Civil Engineers
Abstract: AbstractThe exceptional mechanical properties and bonding ability of epoxy asphalt make it
a cutting-edge modifier for hot-in-plant recycling. This study presented a novel epoxy
modifier (EM) that can be mixed at temperatures ...
