Repair Effect and Repair Mechanism of Microbial Composite Materials on Concrete Surface Cracks

Abstract

This study focused on solving the efficiency problem of microbial repair materials in concrete crack filling. Sodium alginate with a proportion of 1.5% and β-cyclodextrin with different proportions (0%, 0.25%, 0.5%, 0.75%, and 1%) were introduced into traditional microbial repair materials, and a new microbial-sodium alginate-β-cyclodextrin composite system was successfully constructed. The basic properties, durability and microstructure of the modified microbial remediation material were comprehensively analyzed. The experimental results show that the production of calcium carbonate is up to 2.5 g after the addition of β-cyclodextrin, which is 8.5% higher than that of the control group (2.3 g) in the absence of β-cyclodextrin. The water absorption of the material decreases to 54.7%, which is 17.7% lower than that of the control group (66.5%). The thermal shrinkage rate decreases to 0.4%, which is 69.2% lower than that of the control group (1.3%). This synergistic effect significantly improves the durability of the repaired specimens. The mass loss rate after freeze-thaw cycles is reduced to a minimum of 0.8%, which is 36.9% lower than the 1.3% of the unrepaired specimens. The loss rate of compressive strength after freeze-thaw cycles decreases to 4.7%, which is 65.9% lower than that of the unrepaired specimen (13.9%). In addition, after UV aging treatment, the water absorption of the material only increases slightly from 54.7% to 56.8%, an increase of 3.8%.
