Chemical Evolution of Pore Solution in Metakaolin Concrete During Water Evaporation

Medžiagotyra, 2023
Metakaolin concrete is a kind of porous material, which contains a variety of chemical ions in the pores. Solutions in these pores are exposed to the atmosphere and exist evaporation and condensation processes, therefore, the pore solution volume of ...

Yield stress fluids method to determine the pore size distribution of a porous medium [PDF]

, 2014
In this paper a new method is presented in order to determine the pore size distribution in a porous medium. This original technique uses the rheological properties of some non-Newtonian yield stress fluids flowing through the porous sample.

Detecting Elevated Pore Pressure due to Wastewater Injection Using Ambient Noise Monitoring

The Seismic Record, 2022
The injection of large volumes of wastewater has induced earthquakes from June 2010 to July 2011 along the Guy–Greenbrier fault in Arkansas. We measure time-dependent changes in seismic velocities underneath three temporary seismic stations, using the ...
