Magnetic resonance imaging (MRI) reveals water distribution in concrete during freezing. This study quantifies frozen and evaporable water using the SPRITE sequence, achieving submillimetric resolution.

Area of Science:

  • Materials Science
  • Civil Engineering
  • Physics

Background:

  • Understanding water transport in porous materials like concrete is crucial for durability.
  • Freezing conditions significantly impact the physical and chemical properties of concrete.
  • Non-invasive imaging techniques are needed to study water behavior in concrete at low temperatures.

Purpose of the Study:

  • To investigate water density and T2* profiles in hardened concrete and mortar during freezing using magnetic resonance imaging (MRI).
  • To quantify the distribution of frozen and evaporable water within these materials.
  • To achieve submillimetric resolution of proton-density and T2*-relaxation parameters as a function of temperature.

Main Methods:

  • Utilized magnetic resonance imaging (MRI) with a single-point ramped imaging with T1 enhancement (SPRITE) sequence.

  • Obtained water density and T2* profiles in concrete and mortar samples under freezing conditions (-50°C to 11°C).
  • Quantified water distribution by analyzing profile magnitudes and relaxation parameters (T2* < 200 µs, T1 < 3.6 ms).

    • Main Results:

    • Successfully acquired MRI water density and T2* profiles during concrete and mortar freezing.
    • Quantified the spatial distribution of frozen and evaporable water within the samples.
    • Achieved submillimetric resolution for proton-density and T2*-relaxation parameters across the studied temperature range.

    Conclusions:

    • The SPRITE MRI sequence is effective for studying water in porous media with short relaxation times.
    • Detailed insights into water behavior during concrete freezing were obtained.
    • This method provides a valuable tool for assessing material durability under cryogenic conditions.
