Nuclear magnetic resonance relaxation analysis of liquid water 1H nuclei in real porous media (carbonate rocks) with different pore space architecture, polluted with calcium nitrate, is presented to study the kinetics of water condensation and salt deliquescence inside the pore space. These phenomena are responsible for deterioration of porous materials when exposed to environmental injury by pollution in a humid atmosphere. The experiment is performed by following in time the formation of liquid water inside the pore space by T1 and T2 relaxation time distributions. volume ratio.

Abstract

Nuclear magnetic resonance relaxation analysis of liquid water 1H nuclei in real porous media (carbonate rocks) with different pore space architecture, polluted with calcium nitrate, is presented to study the kinetics of water condensation and salt deliquescence inside the pore space. These phenomena are responsible for deterioration of porous materials when exposed to environmental injury by pollution in a humid atmosphere. The experiment is performed by following in time the formation of liquid water inside the pore space by T1 and T2 relaxation time distributions. volume ratio.
