Quantifying the efficiency and quality of air void distributions in concrete
(2022-05)
This work establishes new ways to measure and examine the air bubble distribution within concrete. This is important to provide freeze thaw durability and resistance to oxychloride formation. These bubbles decrease the ...
Impact of water and C3A on Portland cement hydration
(2020-07)
The water-cement ratio (w/cm) is one of the most influential parameters to determine the quality of concrete. A new test method, the Phoenix, has been developed that uses external heat to evaporate the water from the ...
Application of surrogate modeling methods in simulation-based reliability and performance assessment of civil structures
(2020-12)
Structures and infrastructure systems are subjected to various deterioration processes due to environmental or mechanical stressors. Proper performance assessment approaches capable of detecting potential structural damage ...
Biostimulation of trichloroethene dechlorination by organohalide respiring bacteria with enzymatically produced organochlorides
(2021-12)
Anaerobic microcosms were set up for trichloroethylene (TCE) dechlorination with solvent extractable or water extractable organic matter (OM) reacted with the enzyme chloroperoxidase (CPO). CPO-reacted water-soluble OM was ...
Diversity and inclusion of women in the construction industry
(2020-12)
The construction industry has been growing for many years and is expected to continue expanding over the next decade. However, it has experienced a concurrent "widespread and significant shortage" in workers over the past ...
Total quality management and integration of heterogeneous sewer inspection databases for asset management
(2021-07)
Understanding the current condition of sewer pipe networks is a critical step in improving national wastewater systems. Several studies have attempted to develop deterioration models for sewer pipes, and a common concern ...
Sustainability in agricultural practices: Carbon footprint of agricultural groundwater pumping, and microbial denitrification in agricultural soils
(2022-12)
This study aims to identify agricultural energy, water, and nutrient management practices that decrease greenhouse gas (GHG) emissions from irrigated agriculture. Irrigation water and agricultural improvements like fertilizer ...
