Abstract

Nanotechnology will serve as a suitable solution to achieve high performance in future construction and construction. Using this new technology, creativity and innovation can be achieved in the building industry. one of these new technologies of smart concrete is that in recent years, many researches and experiments have been done in scientific research centers around the world, so that the concrete itself is recovered. This is an undeniable fact that concrete structures are prone to cracking. Natural processes caused a crack in the concrete, and through these cracks the harmful substances entered the concrete and caused the corrosion of steel corrosion. to tackle this issue in the conventional method of concrete restorative materials, especially polymers, are used which are also harmful to the environment as well. The method of substitution that scientists have achieved is to use bacteria in concrete and to produce self-healing concrete using bacteria, in addition to reducing the problems associated with the maintenance of concrete for the environment, contributing to the durability and performance of the concrete and increase the useful life of the concrete.
