DEVICE FOR DETERMINATION OF PARAMETERS OF STATE OF CONSTRUCTIONS MADE OF CONCRETE AFFECTED BY AGGRESSION FROM SULFURIC ACID, CONCRETE COROSIMETER

The invention relates to area of industrial, civil and municipal construction and can be used for diagnostics of state of concrete wastewater pipelines. Device for determination of parameters of state of constructions made of concrete that are affected by effect of sulfuric acid aggression includes measuring solid phase electrode that consists of body at one end of which tip is arranged, and at the opposite end the body is closed with cover, current contact and active substance , and comparison electrode that consists of body at one end of which contact tip is provided, at opposite one the body is closed with cover, current contact, weight, active substance, both electrodes are connected by means of cables to device-transformer that includes liquid crystal display and control panel at the end of which split contacts for connection of electrodes are placed. As solid phase electrode antimony-acid electrode is used, bodies of measuring solid phase electrode and comparison electrode are made of plastic by means of process of casting, weight of comparison electrode is made continuous, body of comparison electrode is equipped with pipe that is elongation of contact tip, at that length of the pipe is smaller than length of the body. The invention is based on technical problem of development of device for determination of parameters of state of constructions made of concrete that undergo effect of sulfuric acid aggression where due to new construction of measuring electrode and comparison electrode one should achieve technical result that is in formation of possibility ot measurement of pH on surface of construction made of concrete in any place and at any position of the device, this at the end provides increase of area of application. Винахід належить до галузі промислового, цивільного і комунального будівництва і може бути використаний для діагностики стану бетонних каналізаційних трубопроводів. Пристрій для визначення параметрів стану споруд із бетону, які зазнають впливу сірчанокислотної агресії, містить вимірювальний твердофазний електрод, що складається із корпусу, на одному кінці якого виконаний контактний носик, а на протилежному кінці корпус закритий кришкою, струмопідводу і активної речовини, та електрод порівняння, що складається із корпусу, на одному кінці якого виконаний контактний носик, на протилежному корпус закритий кришкою, струмопідводу, гніта, активної речовини, обидва електроди з'єднані за допомогою кабелів з приладом-перетворювачем, який міс
