Pretensioned concrete girders are currently fabricated using 0.5- or 0.6-in. diameter prestressing strands. In recent years, however, it has become of interest to employ larger-diameter 0.7-in. diameter strands to reduce ...

Increasing municipal and regional water demands have reduced freshwater inflows to the Nueces Delta. These flow reductions impair the marsh ecosystem’s functionality. As part of a United States Army Corps of Engineers ...

This thesis presents the investigation towards increasing the understanding of the effect of polycarboxylate (PCE) High-Range Water-Reducers (HRWRs) on the performance of concrete mixtures, with a special focus on concrete ...

There is a need to continue refining single media fate and transport models used in risk assessments and management. Periodic reviews are required to minimize subjective assumptions and to select and integrate new data ...

Today’s metropolitan areas see changes in populations and land development occurring at faster rates than transportation planning can be updated. This dissertation explores the use of a new dataset from the location-based ...

The long-term performance of the materials that create the building envelope is essential to the long-term durability of buildings and structures. This thesis summarizes published literature on various cladding and ...

The characterization of the swell potential of expansive clay is complicated by the fact that traditional swell testing methods require an excessive amount of time for specimens to swell to their maximum heights. As a ...

Safety reviews of existing roads are becoming a popular practice of many agencies nationally and internationally. Knowing road safety information is of great importance to both policymakers in addressing safety concerns ...

Within the last few decades, the amount of vehicle miles traveled within the US has increased approximately 40% with the construction of new roads only increasing 4% during this same time period. This dramatic increase ...

Alkali-silica reaction (ASR) and delayed ettringite formation (DEF) are expansive reactions that can lead to the premature deterioration of concrete structures. Both have been implicated in the deterioration of numerous ...
