A rather interesting study was presented today as part of a new project by a team of chemical engineering specialists from the DARPA research agency in the USA. The fact is that for the first time they managed to create a “live” cement, made up of several bacterial colonies and able to recover on their own when damaged – this, of course, sounds like some kind of a fantastic novel, but the results of the experiment clearly demonstrate that this is the current reality . Moreover, the research team has already done some preliminary testing using this bacterial cement.
The new type of cement mortar is based on the use of a major bacterial group called Synechococcus cyanobacteria, which has been previously studied in detail by its properties and has become the most suitable candidate for a mortar base. This bacterial group is placed in a special solution of gelatin and sand, and then, under the influence of mineralization and hydrocarbon, the final composition of the solution forms a sufficiently strong cement, which is not inferior in strength to the traditional one – and taking into account its self-healing abilities, it becomes clear that these “living cement blocks ”from DARPA may soon become the new standard in construction work.
Moreover, preliminary studies in this regard have demonstrated that living cement blocks have their own peculiarities and properties – for example, they can quite effectively convert carbon dioxide into oxygen, in the presence of some third-party cheap catalysts.
It is worth noting that the use of this type of cement blocks has its own unique and promising capabilities, not to mention the fact that in this way it is possible to quickly cope with the problems associated with the stability of cement at high humidity. Whatever it was, so far the study of the abilities and properties of the new cement mortar continues, and the team hopes for even more excellent results!
