Abstract:In response to the shortcomings of traditional concrete crack repair materials, a new generation of repair materials has been developed - a microbial repair material based on sodium alginate modification. The method adopts a brushing technique to fix the microorganisms on the cracks to be repaired so that they can deposit calcium carbonate in situ to repair the cracks. This paper carried out a study of the fundamental properties of the repair material, as well as studied the macroscopic morphology and surface … Show more
