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 ...

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 ubiquitous presence and chronic effect of pharmaceuticals is one of the emerging issues in environmental field. As a result of incomplete removal by sewage treatment plants, pharmaceuticals are released into the ...

The presence of pharmacologically active and persistent compounds in drinking water sources is an environmental and public health concern. Sources of pharmaceuticals in the aquatic environment include wastewater treatment ...

Production rates are significantly important for contract time determination procedures as these are essential for estimating the duration of every activity needed to complete a highway construction project. For this reason, ...

The traffic assignment problem (TAP) represents the final and most computationally difficult step in the Urban Transportation Modeling System (UTMS). Prior work has studied several means of solving this problem quickly. ...

Construction Sustainability involves the processes, decisions, and actions during the construction phase of capital projects that enhance current and future environmental, social, and economic needs while considering project ...

Prime coats have been in use for many decades to help protect the base before the subsequent application of bituminous surface treatments. Prime coat is an application of a low viscosity binder onto the base to help protect ...
