Physico-chemical studies of the influence of additives on the biodiversity of structures

Abstract

The article proves that the biodamage of concrete to sewer collectors is due to the activity of microorganisms (bacteria). As a rule, biological production of concrete is equipped with injected products in the metabolism of microorganisms and less in small types of non-average mechanical injections of biological organisms.Bacteriodestruction is caused by representatives of almost all groups of microorganisms. The nature of the damage is determined by the operating conditions in which the concrete works. It was found that the biostability of concrete can be ensured by two complex methods: prevention of surface cracking; creating "bioimmunity" of concrete to the activity of microorganisms. The concrete of the exploited canalizing collectors is fed to the inflows of agressive middlings. When preparing concrete pipes of a special designation, it is especially important to reduce the penetration of the surface ball to concrete. Adjustment of the exploitation characteristics of concrete can be done by adding cement systems and active components to the warehouse, chemically changing the cement with minerals. When interconnecting a complex modifier with cement pieces, the structure and power of the modifier is aware of the difference. The statistic presents the results of the advanced porosity of the modified cement matrix. It has been established that in the newly approved modified cement matrix concrete does not change 5% with calcium hydroxide, but it is necessary to wash away the corrosion-resistant material. As a result of the analysis of modern technologies, it was established that the physical modification can be seen by the way of the winter water and the reduction of the potential power of the cement for the improvement of power, concrete and waterproofness. in the process of damaging the sum.
