RISMesoscale Analysis of Stress Distribution along ITZs in Recycled Concrete with Variously Shaped Aggregates under Uniaxial Compression
Publisher: American Society of Civil Engineers
Abstract: Recycled aggregate concrete (RAC) has attracted tremendous attention from engineering practice and academic research throughout the world as an effective way to resolve the problems caused by the construction and demolition ...
A Modified Low-Reynolds-Number k-ω Model for Recirculating Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A modified form of Wilcox’s low-Reynolds-number k-ω model (Wilcox, 1994) is proposed for predicting recirculating flows. The turbulent diffusion for the specific dissipation rate, ω, is modeled ...
Field Study of Overload Behavior of an Existing Reinforced Concrete Bridge under Simulated Vehicle Loads
Publisher: American Society of Civil Engineers
Abstract: Overload attributable to increased vehicle loads is becoming an increasingly serious issue in highway transportation. Overload results in damages to bridge structures, degradation of their load-carrying capacities, and ...
Metakaolin-Based Geopolymer Features Different Pore Structure Characteristics from Ordinary Portland Cement Paste: A Mechanistic Study
Publisher: ASCE
Abstract: Metakaolin (MK)-based geopolymer is an emerging alterative to cement, but the quantitative understanding of its pore structure is lacking. Prior studies are limited to phenomenological investigations of the influence of ...
Modeling the Behavior of an Aggregate Skeleton during Static Creep of an Asphalt Mixture Based on a Three-Dimensional Mesoscale Random Model
Publisher: ASCE
Abstract: The aggregate skeleton and its evolution under external loads are crucial to evaluate the mechanical properties of the asphalt mixture. This study developed a method to identify the three-dimensionally (3D) aggregate ...
Monotonic and Fatigue Response of RC Beams Strengthened with Near-End Enhanced Embedment Prestressed CFRP Strips
Publisher: ASCE
Abstract: This paper presents a new prestressing reinforcement technique based on prestressed near-end enhanced embedment (NEEE) carbon fiber–reinforced polymer (CFRP) strips for concrete beams. This technique offers significant ...
Experimental Study of the Geopolymeric Recycled Aggregate Concrete

The Effects of Temperature Cyclic Loading on Lead-Free Solder Joints of Wafer Level Chip Scale Package by Taguchi Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the effects of the temperature cyclic loading on three lead-free solder joints of 96.5Sn–3.5Ag, 95.5Sn–3.8Ag-0.7Cu, and 95.5Sn–3.9Ag-0.6Cu bumped wafer level chip scale package ...
Synthesis and Reaction Mechanism of an Alkali-Activated Metakaolin-Slag Composite System at Room Temperature
Publisher: American Society of Civil Engineers
Abstract: Synthesis of geopolymer using metakaolin (MK) usually requires a relatively high curing temperature, which limits the application of MK-based geopolymers in the practice of civil engineering. With the goal of developing a ...
Experimental Investigation of Bond between Near-Surface-Mounted CFRP Strips and Concrete under Freeze-Thawing Cycling
Publisher: American Society of Civil Engineers
Abstract: The technique of prestressing near-surface-mounted (NSM) carbon fiber–reinforced polymer (CFRP) has good potential and future prospects for structural strengthening due to its improvement of the bond between the CFRP and ...
