Novel methods of quantifying curing influence and freeze thaw cycles in the field
(2022-05)
This work developed a flexible resistivity sensor that provides a novel perspective to develop a deep understanding of two important problems for concrete, i.e. curing influence on concrete hydration and freeze-thaw cycles ...
Development of precast, prestressed concrete pavement technology
(2013-12)
Precast prestressed concrete pavement (PPCP) can provide many advantages over other pavement alternatives whether asphalt or concrete. The possible advantages are thinner pavement, faster construction, increased durability, ...
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 ...
Investigating resistivity testing as a method for quality control of concrete mixtures
(2018-05)
Concrete is a composite material. It is a mixture of cement, sand, rocks and water. It is the second largest consumable product in the world. Unfortunately, many of the concrete structures before completing the designed ...
Influence of time dependent properties and temperature effects on the performance of composite bridge girders
(2019-12)
This dissertation seeks to understand the mechanical properties of concrete, and its interaction with steel bridge girders with the purposes of deepening our understanding of the behavior of steel girder bridges made ...
