The use Immobilized Bacteria-Alginate-Chitin for crack remediation

Autor: H. Hermawan, N.A. Rajiani, Ahmad Zaeni, I. N. Sudiana, Prima Endang Susilowati

Publikováno v: IOP Conference Series: Earth and Environmental Science. 299:012010

Cracks in concrete allow water and chemicals to enter, a process that may lead eventually to the unwanted damage of the concrete structure. However, this material is that it easily cracks due to its low tensile strength. The potential of self-healing
