Abstract:This study aims to determine the compressive strength value of K-175 concrete with variations in theaddition of water hyacinth extraction water. The research method used was a laboratory experiment, bydetermining the cement water factor and the composition of the new mixture. In this study, 24 cube testobjects were made using variation of water hyacinth extrac mixtures of 1%, 3% and 5%. The results of thisstudy were the compressive strength value of the average normal K-175 concrete at the age of 14 and28days … 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.
