Abstract:Foamed concrete, comprising a cementitious paste or mortar together with preformed foam, has many attractive properties, perhaps the most useful being its excellent thermal insulation properties, and therefore it can be classified as controlled thermal fill (CTF). Although widely used as a simple backfill, foamed concrete can be designed easily for particular densities (800–1600 kg/m3), flow characteristics (100–300 mm spread), strength (typically less than 10 MPa), and thermal insulation performance (0.2–0.6 … 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.
