The relaxation strength of pore surfaces (ρ2) plays a pivotal role in transforming the nuclear magnetic resonance (NMR) T2 spectrum into size distribution, rendering it an indispensable parameter for characterizing microstructure via NMR techniques. In this study, spontaneous imbibition (SI) experiments, real-time measurements, and mercury intrusion porosimetry (MIP) tests were conducted on three sandstones with different porositirs. We propose novel approach calculating ρ2 using capillary...
Understanding the spontaneous water imbibition mechanism in coal of varying ranks has substantial implications for hydraulic operations and safe, efficient extraction coalbed methane. During imbibition, low-field nuclear magnetic resonance techniques were used to test T2 spectra imaging (MRI) samples, enabling determination signal distribution samples at different time intervals. By combining this with pore structure, we explored migration characteristics during from a microscopic...
With the development of human beings, geothermal exploitation, nuclear waste storage and underground structure fire prevention have received extensive international attention. Currently, magnetic resonance (NMR) tests rocks concrete after exposed to different high temperature conditions been conducted in laboratory field, but there are few reports on studies concrete- rock combination (CRC) samples treatment at (25 o C, 100 300 500 700 C). In order evaluate inferior microcosmic properties...
Tidal effects and vehicle load forming a complicated stress condition in coastal regions have huge effect on the stability of engineering structure. It is therefore necessary to understand physical mechanical behavior for rock-concrete combined body under conditions safety structure design. Therefore, test samples with different roughness carried out this paper. Results show that hysteresis occurred stress-strain curves test. With increasing confining pressure, loop area increases. Besides,...
