Lime sludge replaces cement in various amounts to provide the appropriate mechanical properties. The resulting material is then compared to standard concrete. The research on supplemental cementation resources that equivalent Portland cements's potency without compromising stability. According to the Indian standard (IS 10262–2009), the study used M20, M30, and M40 concrete. Lime sludge replaced cement 0 %, 10 %, 20 %, and 30 %. Also investigated were lime sludge and fly ash mixtures of 10 %, 20 %, and 30 % by weight. Mechanical parameters of concrete classes M20, M30, and M40 were measured at 7 and 28 days. The grades show that the 10 % lime sludge out performed normal concrete. This work represents can be applied as unique additional cementitious substance up to the definite proportions.</div></div>","PeriodicalId":100233,"journal":{"name":"Chemistry of Inorganic Materials","volume":"4 ","pages":"Article 100065"},"PeriodicalIF":0.0,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142322097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
