The results revealed that the performance slightly increased by 1.46 % and 1.96 % at 5 % and 10% of crumb rubber replacement compared to ordinary concrete.","PeriodicalId":50415,"journal":{"name":"Gradevinar","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66958978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ispitivanje je pokazalo da je pri modeliranju ponašanja pukotina potrebno uzeti u obzir međudjelovanje (u vremenu i prostoru) grupe razdjelnica.
