Elements made of reinforced concrete have proved their unquestionable usability. However, in certain cases, the traditional approach involving the use of ribbed bars made of unalloyed steels fails to provide desirable results. The extension of the service life of structures exposed to seawater or road salt is possible through the use of concrete-reinforcement bars made of corrosion-resistant steels. The study presents mechanisms triggering the corrosion of structures made of reinforced concrete, corrosion-resistant steels used in the fabrication of reinforcement bars and exemplary applications of the above-named bars.","PeriodicalId":184101,"journal":{"name":"Biuletyn Instytutu Spawalnictwa","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129756604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, parameters of the above-named functions (power, voltage, resistance) depended on one selected disturbing parameter (length, gas mass stream, gas pressure). To this end, approximations based on power functions were used. The simulation of processes in circuits with forced sinusoidal current and electric arc involved the use of the Pentegov mathematical model. Selected parameters of created models were disturbed using specific rates of change.
