RISEffect of Damage on Moisture Transport in Concrete
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an experimental and analytical study on the effect of distributed cracks (damage) on moisture transport in concrete. Specifically, the writers investigate the following: (1) how damage ...
Assessment of Mitigation Measures against Benzene Breakthrough into Subsurface Concrete Pipe
Publisher: ASCE
Abstract: Work in this paper investigates the efficacy of mitigation measures to minimize the contaminant ingress into subsurface concrete pipes. The 3D study model of the concrete pipe and the soil domain are implemented in Visual ...
Water Absorption and Critical Degree of Saturation Relating to Freeze-Thaw Damage in Concrete Pavement Joints
Publisher: American Society of Civil Engineers
Abstract: Fluid ingress is a primary factor that influences freeze-thaw damage in concrete. This paper discusses the influence of fluid ingress on freeze-thaw damage development. Specifically, this paper examines the influence of ...
Restrained Shrinkage Cracking in Concrete Elements: Role of Substrate Bond on Crack Development
Publisher: American Society of Civil Engineers
Abstract: Several specimen geometries have been used to assess restrained shrinkage-cracking behavior of concrete materials. This paper used a series of restrained slab tests to illustrate the importance of specimen geometry on the ...
Characterizing Lightweight Aggregate Desorption at High Relative Humidities Using a Pressure Plate Apparatus
Publisher: American Society of Civil Engineers
Abstract: This paper describes the results of an experimental study that was performed to obtain desorption isotherms for a wide range of fine lightweight aggregates that are used commercially in North America. The desorption isotherms ...
Quantitative Interpretation of Half-Cell Potential Measurements in Concrete Structures
Publisher: American Society of Civil Engineers
Abstract: The interpretation of half-cell potential measurements in reinforced concrete structures can be a major challenge for civil engineers. The main reason for this is that half-cell potential mapping provides information to ...
Abrasion Resistance of Concrete Exposed to Organic Acids
Publisher: ASCE
Abstract: The objective of this study is to investigate how exposure of concrete to organic acids affects its resistance to mechanical abrasion and to identify the most important factors contributing to its abrasion resistance under ...
Factors Affecting Multiphase Benzene Breakthrough into Drainage Concrete Pipe in the Unsaturated Subsurface Profile
Publisher: ASCE
Abstract: Analyses presented herein explore transport aspects related to benzene breakthrough into gasketed subsurface concrete pipe embedded in an unsaturated soil profile. A series of three-dimensional numerical analyses were ...
Wireless Crack Detection in Concrete Elements Using Conductive Surface Sensors and Radio Frequency Identification Technology
Publisher: American Society of Civil Engineers
Abstract: This paper describes the results of an experimental study that uses radio frequency identification (RFID) technology to detect cracking in concrete elements. A RFID-based sensor is used to monitor the change in electrical ...
