Abstract:
Two series of lightweight concrete mixes made with expanded shale and slag aggregates were prepared for heat exposures between 300 C and 1000 C (572 F to 1832 F)/ To some concretes microfillers such as fly ash, silica flour, and calcined shale dust were added to replace 25 and 40% of the portland cement in the binder.
