Bacteria often confront us with extreme conditions. From boiling water sources to glaciers, bacteria hard conditions we know they love it. The last one, added to all the discoveries made so far, revealed that bacteria can also live in concrete, which we may not even think is possible.
In fact, thanks to some studies carried out in the past, we knew that bacteria made a ‘nest’ in concrete. But new research has shown that bacteria not only nest and live in concrete, but also there. that they continue their development proved. The study also enabled the detection of bacterial species living in concrete.
Study will help prevent ‘concrete cancer’:
The data obtained in the study will help prevent alkali-silica reactions known as concrete cancer. Concrete cancer, in a way, deteriorates the quality of concrete over time. causing them to ‘rot’. This leads to loss of quality in many structures in the long run.
In the study carried out by microbiologist Julie Maresca of the University of Delaware and her team, a large number of concrete molds were examined regularly over two years. As a result of the research, Proteobacteria, Firmicutes and Actinobacteria three types of bacteria was found to live intensely in concrete.
The team thinks that the bacteria in the concrete is largely the source of the gravel and derivative materials in the concrete. In the first place, the results obtained from the study ‘in the determination of concretes with deterioration potential’ is planned to be used.
In the future, it is a substance produced by these bacteria living in concrete and suitable for filling the cracks and pores in the concrete. thanks to calcium carbonate It is hoped that a solution can be produced for concrete cancer. The team says that bacteria do not cause any damage to the concrete, but rather may be a solution to remedy the situation.
