Welcome to 'Characterization of Construction Materials' course !
This lecture introduces mercury intrusion porosimetry (MIP), a technique for measuring pore size distribution and porosity. Learn about:
The principle of MIP: forcing mercury into pores under high pressure, with the pressure required related to the pore size.
The Washburn equation: the relationship between pressure, pore diameter, and contact angle in MIP.
The importance of considering the compressibility of mercury and the sample when interpreting MIP data.
Experimental setup of MIP:
Sample holder containing the material.
High-pressure chamber.
Hydraulic oil for pressurization.
Pressure sensors.
Mercury intrusion volume measurement.
