RISEffects of Mixing Variables on Early-Age Characteristics of Portland Cement Systems
Publisher: American Society of Civil Engineers
Justifying Materials Selection for Reinforced Concrete Structures. I: Sensitivity Analysis
Publisher: American Society of Civil Engineers
Abstract: A substantial amount of research has been performed on the use of high performance construction materials and their effects on the anticipated frequency of maintenance and on the time to repair or replacement. Practical ...
Justifying Materials Selection for Reinforced Concrete Structures. II: Economic Analysis
Publisher: American Society of Civil Engineers
Abstract: To optimize value, design engineers often need to make decisions on what materials should be used in a reinforced concrete (RC) bridge structure exposed to potentially corrosive environments. Part I of this paper series ...
Economic Value of Building Faster
Publisher: American Society of Civil Engineers
Abstract: Owners, developers, and engineers are often challenged with determining the value of accelerating the construction of a project. There is a cost for accelerating the construction of a project to reduce the time required ...
Effects of Constituent Materials and Quantities on Water Demand and Compressive Strength of Controlled Low-Strength Material
Publisher: American Society of Civil Engineers
Abstract: Controlled low-strength material (CLSM) is a self-compacting, flowable, low-strength, cementitious material used primarily as backfill, void fill, and utility bedding in lieu of conventional compacted fill. Potential ...
Alternative Cap Materials for Evaluating the Compressive Strength of Controlled Low-Strength Materials
Publisher: American Society of Civil Engineers
Abstract: This research investigated the influence of different capping materials on the compressive strength of controlled low-strength material (CLSM). These capping materials included a sulfur compound, gypsum capping compound, ...
Service Life of Corroding Galvanized Culverts Embedded in Controlled Low-Strength Materials
Publisher: American Society of Civil Engineers
Abstract: The service life of culverts is often defined by the time, or some factor thereof, in which it takes for corrosion to perforate the pipe material. Significant work has been performed in developing and modifying existing ...
New Model for Estimating the Time-Variant Seismic Performance of Corroding RC Bridge Columns
Publisher: American Society of Civil Engineers
Abstract: Corrosion of reinforcement is a predominant reason for reduced service lives of reinforced concrete (RC) structures exposed to aggressive environments. This deterioration process can lead to damage resulting in capacity ...
Seismic Performance of High-Strength Steel RC Bridge Columns
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of a testing program developed to assess the performance of circular RC bridge columns constructed with ASTM A706 Grade 80 [550] high-strength steel (HSS) reinforcement. Two pairs of columns ...
Time-Variant Reliability Analysis and Flexural Design of GFRP-Reinforced Bridge Decks
Publisher: American Society of Civil Engineers
Abstract: Glass-fiber reinforced polymer (GFRP) reinforcement is being used in bridge decks as a replacement for steel reinforcement. It is thought that since the GFRP reinforcement does not corrode, it could be a more sustainable ...
