Title: A discrete element approach to predicting the uniaxial compressive response of plain concrete
Author: Tannu, Nakul
Date Created: 2017
Subjects--Topical: Mechanical engineering
Description: Discrete element method (DEM) has become the method of choice for modeling the mechanical response of materials with granular structure. The method consists of representing the material as a collection of particles that interact with each other by...

Title: Chemical Characterization of Recycled Concrete Aggregates Using a Handheld X-Ray Fluorescence Device
Author: Dey, Arindam
Date Created: 2020
Subjects--Topical: Civil engineering
Description: Recycled concrete aggregates (RCA) are an important source of material that can be used in construction to mitigate the problems associated with use of virgin aggregates. The volume of waste generated by the construction industry is increasing at ...

Title: Determination and Evaluation of Inputs for Portland Cement Concrete Pavement to Support Local Calibration of MEPDG for North Carolina
Author: Blanchard, Edward
Date Created: 2016
Subjects--Topical: Engineering, Civil engineering
Description: The Mechanistic-Empirical Pavement Design Guide (MEPDG) is a state-of-the-practice tool that is used for the analysis and design of pavements, using mechanical and statistical models that have been developed over the past several decades for the p...

Title: Development of Early-Age and Shrinkage Specifications for Durable Concrete
Author: McEntyre, Memoree
Date Created: 2019
Subjects--Topical: Civil engineering
Description: Historically, concrete strength has been one of the primary properties specified to ensure concrete quality. As the construction industry advances, owners and major stakeholders are increasingly desiring longer lasting, durable concrete pavements ...

Title: Evaluating Corrosive Site Performance of Coastal Bridges
Author: Newsome, Ross
Date Created: 2020
Subjects--Topical: Civil engineering
Description: Corrosion of reinforcing steel in concrete structures, such as bridges, has historically been a concern in coastal environments. Such environments are chloride-rich due to proximity to the salt water found in oceans and brackish water further inla...

Title: Evaluation of J-Rox as a Supplementary Cementitious Material for Concrete Applications
Author: Summers, Allison
Date Created: 2021
Subjects--Topical: Civil engineering, Engineering, Materials science
Description: Supplementary cementitious materials (SCMs) provide a variety of benefits to fresh and hardened concrete. These materials can be found in naturally occurring substances or from by-products or co-products of a variety of industries. However, some o...

Title: Freeze-Thaw Durability Specification for Highway Concrete
Author: Ocampo, Joseph
Date Created: 2022
Subjects--Topical: Civil engineering
Description: The Super Air Meter (SAM) is a new method of testing that correlates to how well concrete can resist damage from freeze-thaw stresses. This test is a modified Type B pressure meter that undergoes a set of sequential pressure steps. The equilibrium...

Title: Internally Cured Concrete Mixtures and Specifications for Highway Infrastructure
Author: Leach, Jacob
Date Created: 2017
Subjects--Topical: Civil engineering
Description: Internal curing is a relatively simple approach to reduce the shrinkage and cracking potential of concrete mixtures, accomplished by placing reservoirs of water within the concrete to provide additional moisture to facilitate hydration of the ceme...

Title: Quality Assurance of Bridge Deck Concrete Overlays using Surface Resistivity Testing
Author: Dillworth, David
Date Created: 2020
Subjects--Topical: Civil engineering
Description: Through years of heavy usage, critical transportation components such as bridge decks are repeatedly subjected to stresses from freeze-thaw cycles, chemical attack and the physical loads. These continual stresses and deterioration mechanisms actin...

Title: Recycled Brick Masonry Aggregate Concrete: Use of Recycled Aggregates from Demolished Brick Masonry Construction in Structural and Pavement Grade Portland Cement Concrete
Author: Cavalline, Tara
Date Created: 2012
Subjects--Topical: Civil engineering
Description: Reuse of construction waste as aggregates is becoming increasingly popular for a number of environmental and economic reasons. In this study, structural- and pavement-grade portland cement concrete (PCC) mixtures were developed using crushed recyc...

Title: Thermal Performance of Precast Concrete Connections Exposed to Fire
Author: Blackstone, Jonathan
Date Created: 2019
Subjects--Topical: Civil engineering
Description: Today, most structural design for fire is governed by the International Building Code. Prescriptive code has proven to be efficient and simple to employ for structural design purposes. However, critical connecting elements in structures can be lef...
