Scientists have developed a new, ultra-strong type of concrete material that is 30% more durable, less prone to cracking, and when they appear, it can even self-repair.
Team from the Polytechnic University of Valenciaachieved this by improving the structure of the cement mixture, crystalline additives, aluminum oxide nanofibers and nanocellulose. In addition to increased strength and self-regeneration of cracks, the new material also requires less maintenance and frequency.holding.
It can serve much longer than usual, about 50 years, which is optimal for structures exposed to aggressive environmental influences.
When checking the material, it was used inconstruction of six large-scale experimental facilities, which are currently being evaluated in real-world structural operations. Two of them are in the Valencian Community, two more in Italy and one each in Malta and Ireland. To monitor strength indicators in real time, autonomous sensors were installed on them.
Earlier, we also reported on the development by Russian scientists of an additive for concrete, which allows it to be poured at temperatures below zero without loss of quality.
