Assessing the Trade-Off Between Sustainability and Resiliency of Reinforced Concrete Alternatives in Corrosive Conditions: An LCA-System Dynamics Approach

Creator:: Moreno Rangel, Erick D.
Abstract:: Concrete has been categorized as a key contributor of CO2 (carbon) emissions into the atmosphere. This is mostly associated with the production of ordinary portland cement (OPC). The concrete and cement industries are pursuing a path to reduce their carbon emissions generally in accordance with the climate change goals outlined...

Influence of Concrete and Construction Parameters on Chloride Test Measurements and Critical Chloride Threshold Limits

Creator:: Vaddey, Naga Pavan
Abstract:: The issue of chloride-induced corrosion of reinforcing steel in concrete and its economic impacts are well-known. Chlorides that cause reinforcement corrosion can be from constituent materials used to prepare concrete or can enter the hardened concrete when the structure is exposed to chloride environments. To minimize the risk of reinforcement...

Critical Assessment of Chloride States and Quantities in Ordinary Portland and Specialty Cements

Creator:: Ahmed, Ahmed Abdulhaq
Abstract:: The constituent materials of concrete often contain chlorides. The presence of chlorides in sufficient amounts can disrupt the passive layer, also known as the passive film, that protects the reinforcing steel in concrete. This disruption can lead to premature corrosion of the reinforcing steel in concrete. To minimize the risk...

Development of a Reliability-Based Framework and Empirical Models for Justifying Allowable Chloride Limits and Quantifying Critical Input Variables for Predicting the Service Life of Reinforced Concrete Structures

Creator:: Shakouri Hassanabadi, Mahmoud
Abstract:: Significant progress has been made over the past 20 years in developing models to estimate the service-life of reinforced concrete systems. The basic understandings of the mechanisms that control the transport of ions and moisture in concrete systems have been well researched and models for determining corrosion initiation, specifically chloride-induced...

The Effects of Construction Practices on Concrete Construction Joint Performance

Creator:: Panduranga Setty, Shreyas
Abstract:: Concrete is the most widely used construction material in the world. When constructing large concrete structures, concrete may have to be placed in multiple lifts. In these cases, fresh concrete is placed on hardened concrete. The interface that is formed between these two lifts of concrete is known as a...

Synergistic Effects of Alkali Silica Reaction (ASR) and Fly Ash on the Corrosion Characteristics of Reinforced Concrete Systems

Creator:: Mazarei, Vandad
Abstract:: Alkali silica reaction (ASR) and corrosion of reinforcement are two deterioration mechanisms in reinforced concrete (RC) structures. These deterioration mechanisms can significantly damage a RC structure and reduce its service life. Supplementary cementitious materials (SCMs) are commonly used to improve the durability of RC systems containing reactive aggregate that are...

Development of a new mixture proportioning method and assessing the influence of material characteristics on flowing concrete mixtures

Creator:: Hendrix, Greg
Abstract:: Cast-in-drilled-hole (CIDH) piles are often constructed to depths that are inaccessible to internal vibration of the concrete. Internal vibration is necessary to consolidate the concrete and, if not performed, then typically inspection pipes are necessary to detect the presence of voids in CIDH piles. Void detection is critical to assessing...

Influence of transport parameters on the fresh and hardened characteristics of ready-mixed concrete

Creator:: Chen, Jiaming
Abstract:: Most specifications for ready-mix concrete (RMC) limit mixing time to 90 minutes and/or truck drum revolution counts (DRC) to 300 before discharge. These specifications have been in place for many years with the objective of ensuring the quality and performance of the finished concrete product. However, limited research has been...

Chemical transformation of rice husk ash for sustainable, constructable, and durable binary cementitious system

Creator:: Prasittisopin, Lapyote
Abstract:: The production of cement and concrete results in the production of large amounts of CO₂ emissions which can have significant negative environmental impacts. Using supplementary cementing materials (SCMs) as a cement replacement is an effective solution to reduce these negative environmental impacts, as most SCMs are waste by-products from other...

Assessing the seismic performance of corroding RC bridge columns

Creator:: Guo, Yisen
Abstract:: Corrosion of reinforcement is recognized as the predominant factor that limits the service life of reinforced concrete (RC) structures exposed to aggressive environments. This corrosion deterioration can lead to damage resulting in capacity loss or even failure. For structures exposed to coastal marine environments or deicing or anti-icing applications, this...

Digitalization of Construction-Phase Information Management by Project Owners

Creator:: Jahanger, Qais K.
Abstract:: Construction is a strategically important industry and its productivity has a significant impact on a nation’s economy. However, productivity in the US construction industry has been widely reported to be on the decline. Among several causes identified, the lack of innovation in project management practices has been described as having...

Performance of High-Strength Steel Reinforcement in Shear Friction Applications

Creator:: Matus Casanova, Nicolas A.
Abstract:: The use of high strength steel reinforcement has the potential to provide economic and constructability benefits when used in reinforced concrete structures. However, more research is needed to justify and confidently allow its use. Current design provisions limit the nominal yield strength of reinforcing steel bars to 60 ksi (420...

High Strength Reinforcing Bars : Concrete Shear Friction Interface Behavior

Creator:: Nielson, Drew R.
Abstract:: Use of high-strength steel (HSS) reinforcing bars could provide constructability and economic benefits for the construction of structures, reducing the initial and ultimately the life-cycle cost of bridge and building structural elements. This thesis summarizes work performed in a research project on the use of HSS reinforcing bars for concrete...
