Abstract:This study deals with the application of the filter paper method to determine water retention curves for mortar and concrete samples. A water retention curve exhibits the relationship between water content and energy state in interstitial water, normally expressed as a negative value when compare to normal conditions of temperature and pressure, being referred to as suction. Considering the water retention curve as a basic characterization tool for unsaturated soils, its usage in the engineering field concerni… 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.
