Description

TECHNICAL FIELD

[0001] The utility model relates to the field of microbial concrete self -repairing technology, especially a kind of microbial concrete self -repairing observation device of simulating dynamic water environment. BACKGROUND

[0002] Microbial concrete refers to adding microorganisms in the form of internal mixing during the preparation of concrete. When the concrete has not yet produced cracks, the microbial spores are in a dry, anaerobic environment and remain dormant. When the concrete begins to crack, water and oxygen will flow into the crack channel and activate the dormant microorganisms. The microbial metabolism can produce sediments to fill the cracks. The self-repairing effect of microbial concrete in different environments is a major concern. For hydraulic microbial concrete, due to the need for service environment, microbial concrete will be subjected to dynamic water erosion for a long time, and its self-repairing effect may be affected. However, there is currently little research on the self-repairing of microbial concrete in dynamic water environment, and the research environment is limited.

[0003] Therefore, there is an urgent need for a microbial concrete self-repairing observation device that can simulate dynamic water environment to solve the above problems. SUMMARY

[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a microbial concrete self-repairing observation device that can simulate dynamic water environment to solve the problems raised in the background art.
