摘要

In the field of construction materials, cracking is amajor problem for the durability of concrete. In this study, atreatment method for concrete based on the biomineralizationusing bacteria could make an effective effect on the structure andthe compressive strength. B. subtilis (natto) with spore-formingability was used to decompose urea to ammonia and carbondioxide. The urease activity of Bacillus subtilis (natto) and thebiomineralization to form calcium carbonate were studied. Also,through the compressive strength and the recovery effect of usingbacterial solution, the self-healing in the concrete microstructurecan be clarified.
