RISExperimental Study of Coal Char–Based Paving Blocks Incorporating Alkali-Activated Fly Ash and Natural Pozzolan
Publisher: American Society of Civil Engineers
Abstract: AbstractThe conventional combustion of coal for energy production is a driver of climate change
and has created environmental concerns. A recent study has found that char derived
from the coal pyrolysis process can be used ...
Multiscale Tip Asymptotics of a Shallow Hydraulic Fracture With Fluid Lag
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study investigates the boundary layer solution in the tip region of shallow hydraulic fractures that propagate with a finite fluid lag. Owing to their proximity to the free surface, shallow hydraulic fractures ...
