The construction of various specialized institutions of military and civil protection involves the use of such building materials that have increased protection against various environmental threats. That is why a team of material engineering specialists from the Federal Far Eastern University in Russia today presented a prototype of their new concrete under the preliminary designation “rubber concrete”. The fact is that, in contrast to the use of any solid connector, the development team decided to bring something non-classical to the structure of concrete and a special rubber alloy was used.
In fact, the word "rubber" here means the use of not rubber itself, but only a set of chemical elements, which in their properties actually repeat the same degree of density and stability as rubber. Because instead of a solid connector, the team used a mixture of rice husk slag, limestone crushing waste and quartz sand, which ultimately led to the creation of a conceptually new material that is characterized by a really impressive level of resistance to cracks and impacts, including those caused by technology .
Moreover, after conducting some additional testing and strength testing of the new concrete formula, specialists noticed that instead of starting to crack, the structure begins to stretch, thereby preventing the critical mark of the crack from growing – and this in turn can provide a high degree counteracting various external shocks and even strong earthquakes.
It is worth noting that concrete itself is something unusual and unique even in the context of many similar developments – taking into account the fact that so far Russian researchers continue to improve the chemical structure of concrete, it becomes clear that most likely very soon a commercial version will be presented. Of course, we are talking about the use of such new concrete exclusively in the framework of various military and civilian developments of a special type.
