Title: DEVELOPMENT, VERIFICATION, AND VALIDATION OF AN APPLIED ELEMENT METHOD SIMULATION FRAMEWORK FOR GLASS LITE FRACTURE, FRAGMENTATION, AND DEBRIS FIELD PREDICTION
Author: Moss, Jonathan
Date Created: 2020
Subjects--Topical: Mechanical engineering, Engineering
Description: In the aftermath of an explosive event, forensic investigators are presented the challenge of characterizing the properties of the explosive device, including the charge size and epicenter of the detonation. Although surrounding infrastructure dam...

Title: DURABILITY OF PAVEMENT CONCRETE WITH REPLACEMENT OF CEMENT BY FLYASH AND PORTLAND LIMESTONE CEMENT
Author: Medlin, Clayton
Date Created: 2016
Subjects--Topical: Civil engineering
Description: The durability of concrete can be directly related to the permeability of the concrete. While the permeability is not the only characteristic that can relate to durability, it is amongst the most important predictors of service life. Lower permeab...

Title: Development of Bridge Management Tools for Predicting Bridge Replacement Projects
Author: Alar, Aidan
Date Created: 2018
Subjects--Topical: Civil engineering
Description: One of the responsibilities of the NCDOT is the prioritization of highway bridge replacement projects throughout the North Carolina transportation system. The Priority Rating Index (PRI) is a multi-criteria formula that is currently used to provid...

Title: EVALUATING CORROSIVE SITE PERFORMANCE AND POLICY WITH CONCRETE ADMIXTURES
Author: Violette, Keith
Date Created: 2020
Subjects--Topical: Civil engineering
Description: The coastline of North Carolina (NC) is home to a large number of state-owned concrete structures such as bridges that can be adversely affected by the aggressive, chloride-rich environments in which they are constructed. To delay the corrosion-re...

Title: EXPERIMENTAL ASSESSMENT OF THE EFFECT OF SODIUM CHLORIDE DEICING AND ANTI-ICING SOLUTIONS ON EXPOSED, COATED, AND REINFORCING STEEL IN HIGHWAY BRIDGES
Author: Diep, Thanh-tu
Date Created: 2014
Subjects--Topical: Engineering
Description: In North Carolina, winter roadway maintenance strategies vary across the state, with some areas using brine for anti-icing pre-treatment, some using granular salts for deicing, and some using a mix of granular salts with traction enhancing materia...

Title: Evaluating Corrosive Site Performance, Service Life, and Policy of Coastal Bridges
Author: Al-Salihi, Taiseer
Date Created: 2022
Subjects--Topical: Civil engineering
Description: Many state-owned concrete structures, such as bridges, line the coast of North Carolina (NC), and these structures are vulnerable to corrosion and degradation in the aggressive, chloride-rich environments where they were built. The North Carolina ...

Title: Hydration of Binary and Tertiary Fly ash and Quicklime Blended Cement Paste System
Author: Ojaruega, Akpovona
Date Created: 2018
Subjects--Topical: Civil engineering
Description: The hydration kinetics in blended cementitious systems with fly ash are quite different from those in conventional cementitious systems. The pozzolanic nature of fly ash not only reduces the rate of hydration in cement-fly ash blends, but also rea...

Title: Optimized Aggregate Gradation Concrete Mixtures with Cementitious Material Reduction
Author: Theilgard, Peter
Date Created: 2022
Subjects--Topical: Civil engineering, Materials science
Description: Optimized aggregate gradation concrete mixtures with reduced cementitious materials are emerging in concrete mixture design in an effort to reduce costs and CO2 emissions while improving the concrete’s durability characteristics. Optimizing the ag...

Title: Performance of Portland cement concrete containing chemically beneficiated high loss on ignition fly ashes with air entrainment
Author: Ojo, Taye
Date Created: 2018
Subjects--Topical: Civil engineering
Description: The use of fly ash as a partial replacement of Portland cement in concrete production has been widely accepted and has been proven to be a successful practice that enables production of economical durable concrete. However, following the Clean Air...

Title: RAPID AND DYNAMIC LOAD TESTING OF INSTRUMENTED PZ27 STEEL SHEET PILES
Author: Rice, Corey
Date Created: 2020
Subjects--Topical: Civil engineering
Description: Pile foundations are typically used for structures underlain by weaker soils in order to increase the soil resistance and, subsequently, the axial capacity. In bridge abutments, sheet piles are typically used as facing elements for soil retention ...

Title: Sensitivity Analysis of Production Variables of Geopolymer Cement Concrete to Mechanical and Durability Characteristics
Author: TREJO, MARIA
Date Created: 2016
Subjects--Topical: Civil engineering
Description: Geopolymer cement is an alternative binder manufactured from fly ashes that can fully replace portland cement in traditional reinforced concrete applications. As a viable material for precast components, geopolymer features very rapid strength dev...
