Abstract:In the present study, samples of excavated waste clays were thermally activated at 550 °C and 650 °C, these clays with low kaolinite content and presence of dickite have a limited industrial exploitation but are widely availability in developing countries and have the potential to use as pozzolanic material. The effects on the calcium hydroxide fixation and the compressive strength were evaluated in lime pastes and mortars blended with calcined excavated clays. The experimental results and statistical modellin… 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.
