RISEstimating Stress Relaxation and Cracking Potential of High-Strength Concrete Reinforced with Polyvinyl Alcohol Fiber at Early Age
Publisher: ASCE
Abstract: High-strength concrete (HSC) with a low water-to-cement (w/c) ratio always exhibits high shrinkage at an early age. Concrete with shrinkage that is subjected to restraint is prone to trigger harmful cracking, which facilitates ...
Strengthened Relationship between Tropical West Pacific and Midsummer Precipitation over Northeast China after the Mid-1990s
Publisher: American Meteorological Society
Abstract: The relationship between the tropical west Pacific (TWP) and East Asian summer monsoon/precipitation has been documented in previous studies. However, the stability for the signals of midsummer precipitation in the TWP sea ...
Seismic Analysis of Nonhomogeneous Slopes with Cracks Using a Discretization Kinematic Approach
Publisher: American Society of Civil Engineers
Abstract: In practice, slopes with cracks are very common, particularly in earthquake-prone areas. The slope soil properties exhibit spatial nonhomogeneity because of the geological and environmental effects. This article investigates ...
Experimental Investigations on Early-Age Stress Relaxation and Cracking Behavior of Supersulfated Cement Concrete with Different Activator Proportions
Publisher: American Society of Civil Engineers
Abstract: As an alternative to ordinary portland cement (OPC), supersulfated cement (SSC) has better properties in terms of being environmentally friendly as well as durability in aggressive environments. Nevertheless, the research ...
Production of Rapid-Hardening Magnesium Oxysulfate Cement Containing Boric Acid
Publisher: ASCE
Abstract: Rapid-hardening magnesium oxysulfate (MOS) cements were prepared using a high-activity light-burned magnesia (HA-LBM) powder and boric acid (BA). The early hydration, compressive strength, phase composition, microstructure, ...
Effect of Direct Liquid Cooling Technology With Flow Guide Integration on Avionics Devices Thermal and Electrical Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the application of various highpower electronic devices to improving aircraft comprehensive performance, there has been a significant interest in the use of high heat flux dissipation technology to maintain an effective ...
