Is Cement Paste Modified with Carbon Nanomaterials Capable of Self-Repair after a Fire?

Abstract This manuscript presents preliminary results on the cement paste potential, with and without carbon nanomaterials, to heal high-temperature cracks. Cement beams were subjected thermal loading of 200°C 400°C after 28 days water curing. High temperature caused formation microcrack networks specimen’s surface. Self-healing was achieved by exposing cracked samples cyclic immersion. The efficiency process evaluated based crack closure mechanical properties recovery 24 days. indicated a distinct dependence healing temperature. Carbon nanotubes had positive effect self-repair efficiency.
