This work presents the analysis of a dynamic neutron tomography experiment. The goal is to visualize the internal water flow in a variety of cement-based materials that contain superabsorbent polymers.
During hardening of the cement paste, the polymers seem to release their entrained water for internal curing purposes.
Per-pixel analysis of the time attenuation curve using piecewise-constant functions clearly visualizes this feature and may lead to interesting results and optimization of the material.
