Methods and devices for improved measurement of the thermal expansion and/or chemical reactivity of aggregates used in concrete and for similar substances. Aggregate is placed into the chamber of a metallic container having an enlarged opening. The aggregate is placed in a water bath, and a tightly sealable lid is placed onto the container. Sep 30, 2018 The recycled coarse aggregate was obtained from demolished concrete which was used as a foundation for a universal testing machine (UTM) at the Materials Research and Testing Center (MRTC) of the Ethiopian Institute of Architecture, Building Construction and City Development (EiABC), Addis Ababa University.
