The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

Краткое описание

The large number of ways to mix and use concrete and its reinforcement with steel is in contrast to the number of technologies for the destruction of old construction substances. Especially for buildings or constructions, made of heavy concrete with a high degree on steel-reinforcement (i.e. nuclear reactors, bunkers, industrial smoke stacks), the number of usable and affordable technologies is very small. Different from known technologies an additional/alternative method and technology was developed, which uses a DC-Plasma torch with non-transferred arc. As a first step of a project a special designed DC-plasma torch with a power of approx. 40 kW was used. To reduce the costs, the torch was runned with nitrogen only or mixtures of mainly nitrogen with a small amount of argon. The generated thermal plasma with its high kinetic energy was able to melt and cut any construction material, independent from the presence and degree of steel reinforcements up to large depths and with a high velocity. In various tests the destruction of steel-reinforced concrete plates up to a thickness of 200 mm was successfully demonstrated by continuous cutting or defined hole drilling. In the latter case the samples were finally deconstructed to small blocks by thermally induced cracks between the holes. Another tested application is the decorative treatment of surfaces of natural stones (i.e. Granite) or the selective separation of such materials by thermally induced cracks.
