The MSW is a very fine powdery material, and in this case, it was used as a partial replacement of fine aggregate in the mixture. The reference ordinary concrete mixtures without MSW were created for evaluation. The results of concrete density, compressive strength, electrical resistivity, and rapid chloride permeability were obtained and some of them were measured continuously to determine the influence of the chemical admixtures on these characteristics over time. It was found that in general, the MSW substitution slightly lowers the mechanical and durability parameters, but MSW in combination with the chemical admixtures improves the compressive strength in comparison to the reference concrete with the addition of AEA.<\/jats:p>","DOI":"10.3390\/ma15238287","type":"journal-article","created":{"date-parts":[[2022,11,22]],"date-time":"2022-11-22T08:29:58Z","timestamp":1669105798000},"page":"8287","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effect of Chemical Admixtures on Mechanical and Degradation Properties of Metallurgical Sludge Waste Concrete"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1478-5027","authenticated-orcid":false,"given":"Petr","family":"Lehner","sequence":"first","affiliation":[{"name":"Department of Structural Mechanics, Faculty of Civil Engineering, VSB-Technical University of Ostrava, Ludv\u00edka Pod\u00e9\u0161t\u011b 1875\/17, 708 33 Ostrava, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9218-5484","authenticated-orcid":false,"given":"Marie","family":"Hor\u0148\u00e1kov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Structural Mechanics, Faculty of Civil Engineering, VSB-Technical University of Ostrava, Ludv\u00edka Pod\u00e9\u0161t\u011b 1875\/17, 708 33 Ostrava, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8877-5334","authenticated-orcid":false,"given":"Jan","family":"Pizo\u0144","sequence":"additional","affiliation":[{"name":"Department of Building Processes and Building Physics, Faculty of Civil Engineering, Silesian University of Technology, Akademicka Street 5, 44-100 Gliwice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4110-5581","authenticated-orcid":false,"given":"Jacek","family":"Go\u0142aszewski","sequence":"additional","affiliation":[{"name":"Department of Building Processes and Building Physics, Faculty of Civil Engineering, Silesian University of Technology, Akademicka Street 5, 44-100 Gliwice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"012021","DOI":"10.1088\/1755-1315\/444\/1\/012021","article-title":"Sustainability Assessment of Concrete Mixes","volume":"444","author":"Hrabova","year":"2020","journal-title":"IOP Conf.
