RISModeling of Ionic Diffusivity for Cement Paste with Solid Mass Fractal Model and Lattice Boltzmann Method
Publisher: American Society of Civil Engineers
Role of ITZ in the Degradation Process of Blended Cement Concrete under Magnesium Sulfate Attack
Publisher: ASCE
Abstract: Although the importance of the interfacial transition zone (ITZ) to sulfate attack is obvious, the relation between the ITZ and the rate of degradation is still unclear. The impact of ITZ volume content on the degradation ...
Analysis of the Bearing and Damage Mechanism in Steel–Steel Fiber–Reinforced Concrete-Composite Member
Publisher: ASCE
Abstract: In order to avoid certain construction difficulties in a traditional steel reinforced concrete (SRC) structure, like the interference between reinforcing steel and rebars or poor concrete pouring quality, steel–steel ...
Numerical Investigation of Grouting of Rock Mass with Fracture Propagation Using Cohesive Finite Elements
Publisher: American Society of Civil Engineers
Abstract: The grouting of a rock mass is frequently adopted in engineering to enhance the strength and integrity of jointed rock. Based on the principle of hydraulic fracturing, grouting slurry with high pressure is injected into ...
Two-Step Seismic Calculating Method and Seismic Features of SRC-RC Hybrid Frame Structure
Publisher: American Society of Civil Engineers
Abstract: For further improving the seismic design of steel-reinforced concrete (SRC)—RC frame structures, a two-step seismic calculating method is proposed as a supplement to the current Chinese standard for structural seismic ...
Interactions between Organic Chelation Agents and Ions in Seawater for Accelerating Self-Healing of Cracks in Cement Paste
Publisher: ASCE
Abstract: To improve the durability of cracked concrete structures in a marine environment by self-healing of cracks, the efficiency and speed of self-healing need to be increased. In this study, the interactions between organic ...
Effects of Drying-Wetting Cycles on the Mechanical Behavior of Reconstituted Granite-Residual Soils
Publisher: ASCE
Abstract: In Central South of China, granite residual soil (GRS) is one of the main subgrade soils for transportation infrastructures. To further understand the effects of drying and wetting (D-W) cycles on the mechanical responses ...
Effect of Excavation Disturbance on Clayey Soil Mechanical Properties and Pile Capacity
Publisher: ASCE
Abstract: Excavation causes disturbance to the surrounding soil, affecting the soil’s mechanical properties. This study presents a case study to investigate the effect of excavation disturbance on soil properties and pile capacity ...
Study on the Mechanical Properties of Steel Slag Cement–Solidified Silt Soil and the Law of Chloride Ion Transport under Different Erosion Times
Publisher: ASCE
Abstract: To study the influence of chloride erosion on the mechanical properties of steel slag cement–solidified silt soil and the law of chloride ion migration, indoor tests were carried out on the physical and mechanical properties ...
Study on Strength Characteristics and Hardening Mechanism of Alkali Residue–Based Lightweight Soil
Publisher: ASCE
Abstract: The accumulation of alkali residue has led to significant contamination of soil, air, and water, posing a hazardous threat to the environment. To address this issue, a technology and method for producing alkali residue–based ...
