The cured mortar specimens were imaged by X-ray CT on different days of the experiment. Utilizing Hounsfield Unit values as guides, void volumes and ratios were identified and measured by Matlab software. SEM images supported the X-ray CT results. It is shown that X-ray CT analysis is capable of assessing the development of macro voids in the mortar specimens.</dc:description><dc:publisher>ELSEVIER SCI LTD</dc:publisher><dc:date>2012</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/bayburt/14016</dc:identifier><dc:identifier>https://doi.org/10.1016/j.conbuildmat.2012.02.084</dc:identifier><dc:identifier>0950-0618</dc:identifier><dc:language>en</dc:language><dc:relation>Construction and Building Materials</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/14016</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
