On the contrary, the amount of added plastic waste has oscillated up to incorporate 50%, 60% and 70% over the weight of the plaster.\u0000In comparison to a reference sample, the obtained compounds are characterized by having a higher Shore C hardness, a lower absorption by capillarity and a decrease in their values of mechanical resistance.\u0000The addition of plastic waste to a plaster matrix can be considered as a possibility to obtain compounds of greater sustainability to be used in the field of sustainable construction.","PeriodicalId":34803,"journal":{"name":"Darnios Aplinkos Vystymas","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47181691","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}

(2004) internetinės svetainės kokybės vertinimo modelis. Tyrimas atskleidė, jog iš galimų 110 balų, analizuojama internetinė svetainė surinko 87. Tai nėra prastas rezultatas, tačiau internetinė svetainė turi tobulinamų funkcijų, kurios ateityje padės siekti aukščiausio rezultato.","PeriodicalId":34803,"journal":{"name":"Darnios Aplinkos Vystymas","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46376082","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}
