RISDevelopment of Preplaced Alkali-Activated Coral Concrete for a Marine Environment
Publisher: ASCE
Abstract: The use of coral aggregate (CA) in marine concrete can greatly reduce project costs and periods. An environmentally friendly alkali-activated material (AAM) was used to grout CA to produce preplaced alkali-activated coral ...
A Novel Model for Shear Strength Prediction of a Steel–UHPC Composite Structure Considering Interface Friction
Publisher: American Society of Civil Engineers
Abstract: Existing studies have shown that the interface friction force positively affects and improves the shear behavior at the stud-connected steel–ultrahigh performance concrete (UHPC) interface. However, the effects of the ...
Effect of Synthesized Sol-Type Nano-SiO2 on the Mechanical Properties and Drying Shrinkage of Fly Ash–Slag-Based Geopolymer
Publisher: ASCE
Abstract: In this study, nano-SiO2 was synthesized using the sol-gel method to modify the properties of fly ash-slag geopolymers (FASGs). FASGs with six contents of sol-type nano-SiO2 (0, 0.1%, 0.2%, 0.3%, 0.4%, and 0.5%) and two ...
Mechanical and Electromagnetic Shielding Properties of Amorphous FeSiB Ribbon–Reinforced Gypsum Composite Board
Publisher: American Society of Civil Engineers
Abstract: Gypsum-based composite boards reinforced with mono- and multilayer perforated amorphous Fe78Si9B13 ribbons were fabricated by pouring gypsum slurry directly into molds with prelaid epoxy-resin-coated amorphous ribbons. The ...
Nanomechanical Experiments and Molecular Dynamics Explorations for the Deterioration Evolution of Asphalt Driven by Chloride Salt Erosion
Publisher: ASCE
Abstract: The salt erosion environment will lead to the deterioration of asphalt pavement performance and seriously restrict the service life and sustainability of asphalt pavement. In this research, the evolution mechanism of asphalt ...
