A prototype machine developed for this research produced the fibers for the study. Parameters investigated include: volume fraction of the fibers; fiber equivalent aspect ratio; and the compressive strength of the mortar matrix. The high performance fiber reinforced cement composites exhibiting strain hardening and multiple cracking behaviors can be obtained with a proper combination of the parameters. Also provided is a comparison with hooked and straight steel fibers.","PeriodicalId":400110,"journal":{"name":"SP-216: Innovations in Fiber-Reinforced Concrete for Value","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121544587","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}

The microcrack evolution of plain concrete and fiber reinforced concrete were investigated with acoustic emissions and electronic speckle pattern interferometry. When steel fibers are introduced in the concrete mix, the size effects are usually less pronounced on the structural strength and ductility, but the considered size ranges show that the fiber length should be chosen adequately relative to the size of the specimen.","PeriodicalId":400110,"journal":{"name":"SP-216: Innovations in Fiber-Reinforced Concrete for Value","volume":"302 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132117776","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}

Reviewed are the various issues related to spalling, such as reinforcement exposure and impact of safe environment in fire locations. Also reviewed are results from a number of studies to illustrate the critical parameters that govern spalling in HSC structural members under fire conditions. The paper presents data from experimental studies to illustrate the effectiveness of polypropylene fibers in minimizing spalling in HSC structural members.","PeriodicalId":400110,"journal":{"name":"SP-216: Innovations in Fiber-Reinforced Concrete for Value","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121766487","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}
