Factors Affecting Fuel Transport of Firefighting Foam
… gaps, identifying the properties and features of surfactants used in firefighting foam that will prevent the transport of liquid fuel through the surfactant solution was imperative. To achieve that, this research was performed exclusively on single surfactants that have applications in …

Multiscale Investigation of Surfactant-Driven Fuel Resistance
… stems from the unique ability of fluorinated surfactants, including per- and polyfluoroalkyl substances (PFAS), to rapidly spread across fuel surfaces and form stable barriers that prevent vapor release. However, increasing evidence of PFAS toxicity, persistence, and environmental accumulation …

Development of foamed concrete : enabling and supporting design
… stress, plastic viscosity, material fineness and surfactant types. The bubble diameters have been shown to range between 0.1 to 0.5 mm. Bubbles less than 0.35 mm in diameter correspond to stable mix with a drop in level of less than 5% in height in densities of 1000 kg/m3 and higher. The big …
