Abstract:Synopsis The resistance to crack propagation in glass-fibre-reinforced cement paste has been assessed by using a technique developed for measuring the fracture toughness of unreinforced cement pastes and mortars. The values measured with the fibrous material are not true toughness values but can be treated as such for small crack growths or used for relative assessment of the resistance to cracking over a larger range of growth. The material tested was an OPC/pfa matrix with chopped glass-fibre distributed at… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
