SPbPU researchers have created new technologies for self-repair of concrete🤩 The first method is the use of Hay-Bacillus bacteria. They are activated when cracks appear and produce calcite. It fills all the cracks, restoring the structure of concrete. The second method is the use of microcapsules with grout. When a crack forms, the capsules burst, releasing the contents and filling the crack. Such formulations are capable of multiple repairs. Thanks to the development, the service life of concrete structures — foundations, bridges and others — will increase, and the cost of repairing them will decrease. Now scientists are conducting numerous tests and plan to adapt the material for specific applications in construction. The work is being carried out under the guidance of leading researcher of the Laboratory of Self-Repairing Structural Materials Sabri Mohanad Muayad Sabri and chief researcher Vatin Nikolay Ivanovich.
