RISStudy on the Physical and Mechanical Properties of Mortar with Added Silica Fume, Nano-CaCO<sub>3</sub>, and Epoxy Resin under the Action of Salt and Freeze–Thaw
Publisher: ASCE
Abstract: Many engineering problems are caused by the destruction of cement-based materials through the combination of salt mixtures and freezing/thawing. To improve the performance of cement-based materials under harsh environmental ...
Mechanical and Microstructural Properties of Nanoconcretes Exposed to Low-Temperature Curing
Publisher: ASCE
Abstract: Low-temperature curing significantly affects the performance of concrete. This study explored the mechanical and microstructural characteristics of concretes modified with three kinds of nanoparticles [i.e., nano-CuO (NC), ...
Deterioration Behavior of Geopolymer-Stabilized Soil under the Coupling Action of Freeze–Thaw Cycles and Chloride Salt Erosion
Publisher: American Society of Civil Engineers
Abstract: Geopolymer-stabilized soil is a low-carbon material widely used in engineering, but it often faces complex engineering environments. In cold regions, factors such as low temperature curing, chloride salt erosion, and ...
Effect of Freeze–Thaw–Dry–Wet Cycles on the Shear Behavior of Silty Clay Salinized in Wetting Processes
Publisher: American Society of Civil Engineers
Abstract: In cold and arid saline areas, the mechanical properties of soils are usually significantly affected by some complicated conditions, especially the coupled effects of the freeze–thaw–dry–wet (F–T–D–W) cycles and soil ...
Estimating Unfrozen Water Content in Frozen Soils Based on Soil Particle Distribution
Publisher: ASCE
Abstract: The unfrozen water content is a result of soil freezing, and its variation is closely related to temperature. To study the change in unfrozen water content, a relationship between water pressure and ice pressure is built ...
