Sensitivity of Half-Cell Potential Measurements to Properties of Concrete Bridge Decks
… effects of age, chloride concentration, concrete cover thickness, spatial position, temperature, and presence or condition of epoxy coating on half-cell potential measurements of concrete bridge decks typical of those in Utah. The laboratory testing associated with this research followed a …

Effect of Initial Surface Treatment Timing on Chloride Concentrations in Concrete Bridge Decks
… chloride ingress. In consideration of concrete cover thickness and the presence of stay-in-place metal forms (SIPMFs), the objective of this research was to determine the latest timing of initial surface treatment applications on concrete bridge decks subjected to external chloride loading …

Structural settings inferred from gravity, magnetic and seismic data for Durban Basin, east coast offshore of South Africa
… Zululand Basin. The rift Mesozoic Durban Basin covers an area of about 10 000 km² between Port Shepstone Arch and the Zululand Basin. Structurally, it is complex with multiple fault systems and folds. Its development is a result of early extension of the East African plate, break-up of Godwana …

Exploring light transmission through ice-snow cover and water in lakes
… importance becomes even more critical during ice-covered periods when external forces, like wind, are inhibited by the ice-snow cover. Despite this, a fraction of solar radiation can still penetrate the ice and snow, becoming the main external source of energy. This radiative heating destabilizes …

Field Emissions of Methane and Nitrous Oxide from California Landfills
… and oil and gas operations, population density, cover conditions and percentage of cover types, age of waste, waste profile, landfill style and configuration, and disposal of waste tires. Fifteen representative sites were chosen for the aerial portion of testing, and of those fifteen, five sites …

Development of an Index for Concrete Bridge Deck Management in Utah
… data were analyzed using statistics, and age, cover, and half-cell potential were ultimately selected for inclusion in a new Utah Bridge Deck Index (UBDI); these variables effectively reflect chloride-induced corrosion mechanisms active on Utah bridge decks, are highly correlated to …

Modelización del deterioro de tableros de puentes de hormigón por difusión de cloruros y corrosión de la armadura pasiva
… induces tensile stresses in the concrete cover. Basically, the governing equations in modelling of chloride ingress and transport into concrete refer to ion diffusion, but also to other phenomena like convection (motion of dissolved substances caused by flow of water in pore solution of …
