Coupling Transport Codes with Geochemical Models
(2006-12-15)
Multi-dimensional reactive transport models are needed for understanding the fate and transport of the metal contaminants in groundwater aquifers. The goal of this research is to develop a framework for coupling the MINTEQ ...
Creep and Shrinkage Behavior of Concrete in Segmental Bridge Applications
(2020-11-23)
The objective of this study is to accurately predict creep and shrinkage behavior of concrete in the I-59/I-20 segmental bridge located in downtown Birmingham, Alabama. In order to quantify creep and shrinkage, four different ...
Creep and Shrinkage Behavior of Concrete in Segmental Bridge Construction
(2018-11-15)
This thesis is aimed at quantifying the shrinkage and creep behavior of the I-59/I-20 segmental bridge located in downtown Birmingham, Alabama. Also, two laboratory concrete mixtures of different coarse aggregate types ...
Creep Behavior of Self-Consolidating Concrete
(2008-08-15)
Self-consolidating concrete (SCC) is a highly flowable material that has the ability to improve the quality and durability of structures; however, much is still unknown about the hardened properties of this material, ...
Data Usage Optimization for Cost Estimating in Asphalt Paving Projects Using a Cost Indexing System
(2018-04-30)
During the last decade, the transportation construction industry has seen an increase in the implementation of historical bid-based cost estimating practices by various state transportation agencies (STAs). The American ...
Decreasing Lead Bioaccessibility In Soils With Phosphate Amendments
(2006-08-15)
Ingestion of Pb-contaminated soil has been proposed as a primary exposure pathway for elevated blood Pb levels in young children (Dudka and Miller, 1999). Children are often exposed to soils contaminated with toxic metals ...
Degradation of Estradiol in Water and Soil Using a New Class of Stabilized Manganese Dioxide Nanoparticles and Hydrodechlorination of Triclosan Using Supported Palladium Catalysts
(2015-07-29)
Pharmaceuticals and personal care products (PPCPs), such as 17 beta-estradiol (E2) and triclosan (TCS), are endocrine disruptors that have been found in surface water and groundwater. The low concentration of these endocrine ...
Degradation of Metronidazole by carboxymethyl cellulose stabilized iron sulfide nanoparticles in water and soil phases
(2018-05-16)
The removal of Metronidazole (MNZ) from water and soil phases by iron sulfide (FeS) nanoparticles was investigated. From the results, for the batch test, 10 mg/L MNZ in the solution can be fully removed by the 350 mg/L FeS ...
Degradation of Phenolic Compounds Using Laccase or Peroxidase Enzymatic Treatment
(2010-07-16)
To remove ammonia from wastewater most refineries use biological treatment employing suspended biomass because there is no secondary pollutant. The main purpose of biological treatment is to accelerate the oxidation process ...
Desiccation Cracking Behavior of Sustainable and Environmentally Friendly Reinforced Cohesive Soils
(2020-04-17)
Desiccation cracking of cohesive soils is the development of cracks on the soil surface as a result of a reduction in soil water content. The decrease in soil surface area owing to the desiccation of cohesive soils has an ...
Design & Construction Planning of Rapid Bridge Deck Replacement Systems for I-59 Bridges at Collinsville, AL
(2011-12-13)
Many bridges in the Birmingham area have deteriorated decks that need to be rehabilitated or replaced. Several of these are major interstate bridges that carry large volumes of traffic. Rehabilitation or replacement of the ...
Design and Characterization of Cold Recycled Foamed Asphalt Mixtures with High RAP Contents
(2018-04-24)
Cold recycling with foamed asphalt has been considered as a sustainable pavement rehabilitation technology. Although different mix design methods have been proposed, there is no widely accepted standard. The effects of ...
Design and Construction of a Rainfall Simulator for Large-Scale Testing of Erosion Control Practices and Products
(2017-04-14)
Soil erosion and the resulting sediment deposition constitutes one of the greatest pollutants in our nation’s waterways. Construction projects often generate large areas of exposed soil that remain disturbed throughout the ...
Design Guidance and Development of Construction Stormwater Technologies
(2020-10-19)
As one of the largest sources of nonpoint source pollution, soil erosion has become an increasingly important topic in the U.S. Construction sites. Erosion and sediment control (ESC) practices are commonly used on ...
Design of Lateral Support for Non-Integral Wing Walls of Culverts
(2017-11-20)
Traditionally, culverts are built with integral wing walls. This style of culvert has shown consistent issues at the joint where the wing wall frames into the culvert bodies due to differential settlement and inadequate ...
Destruction of Perchlorate and Nitrate by Stabilized Zero-valent Iron Nanoparticles and Immobilization of Mercury by a New Class of Iron Sulfide Nanoparticles
(2007-12-15)
This research compares representative standard strong-base anion (SBA) and weak-base anion (WBA) exchangers, a bifunctional resin (A-530E), a class of polymeric ligand exchangers (PLE’s), and an ion-exchange fiber (IXF) ...
Determination of Elastic Constants and Damage in Ceramic Matrix Composites Using Ultrasonic Wave Speed Measurements
(2006-12-15)
