Abstract: Ultra-high-performance concrete (UHPC) refers to cement-based materials exhibiting
compressive strength higher than 150 MPa, high ductility and excellent durability. High
cracking tendency of UHPC derived from autogenous shrinkage can be a concern due to its
high binder content and low water to binder ratio. This paper reviews early hydration and
shrinkage development of UHPC. The effect of supplementary cementitious materials, such
as silica fume, slag, fly ash, limestone powder, rice husk ash and nano-materials, on
hydration and microstructure are reviewed. The effect of cement, water content, aggregate,
chemical admixtures, supplementary cementitious materials (SCMs), curing conditions, and
fiber on autogenous shrinkage of UHPC were summarized. Different methods have been
developed to compensate and/or reduce the early-age shrinkage of UHPC.
