Abstract This study focuses on the early-age shrinkage of ultra-high performance concrete (UHPC) with high-volume mineral admixtures. Two low cement UHPC mixtures, which have similar compressive strength with control mixture, were obtained with high-volume ground granulated blast furnace slag (GGBFS) or fly ash (FA) replacements. The effects of exposure temperature on autogenous shrinkage of sealed specimens and drying shrinkage were studied at early-age (
