Most lubricants are produced from petroleum oil which is poorly biodegradable and toxic in nature. Hence these lubricants are highly undesirable due to environmental hazards and the health and safety of the operator. Bio-Lubricants like Castor Oil have found a potential scope in research and are being used in various applications as a substitute for these chemical lubricants. This paper examines the Tribological Properties of developed Bio-Lubricants, prepared using Castor Oil and Neem Oil in a mixing ratio of 20%. Wear and Friction analysis has been carried out using Pin on Disc apparatus at varying loads, which has shown that the blend of Castor Oil as a base with 20% Neem Oil has promising properties, with around 70% reduction in wear rate at specific loads, hence showcasing a tremendous capacity for being used in maintenance applications. An overall reduction in wear and coefficient of friction was observed in the developed mixture, making it a potential environment-friendly replacement for chemical lubricants and an upgrade over Pure Refined Castor Oil.","PeriodicalId":42984,"journal":{"name":"Journal of Materials and Engineering Structures","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135953591","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}

Based on this, in this paper, the influence effects and mechanisms of curing methods on early shrinkage and crack resistance of concrete were investigated through indoor tests to simulate strong wind environment and high temperature environment in summer, and the applicability of different curing methods in engineering practice was verified by on-site experiments. The indoor experiment results demonstrated that the concrete was more prone to cracks under strong wind than under high temperature. The indoor and on-site experimental results showed that it was difficult to ensure a crack-free concrete surface by employing traditional geotextile, simply spraying curing agent or using only water-saving moisturizing curing film, among them, utilizing composite geotextile curing film has the best anti crack effect. In addition, incorporating polymer water absorbent resin enables the concrete to be cured internally, so it can be used as a supplementary curing measure to further improve the crack resistance of concrete in strong wind and high temperature weather.","PeriodicalId":42984,"journal":{"name":"Journal of Materials and Engineering Structures","volume":"56 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83479330","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}
