AB Reducing cement CO2 footprint is a societal need. This is being achieved mainly by replacingan increasing amount of Portland clinker by supplementary cementitious materials. However,this comes at a price: lower mechanical strengths at early ages due to slow pozzolanic reaction(s).This is being addressed by using accelerator admixtures. In this context, calcium silicate hydratenucleation seeding seems to have a promising future, as it can accelerate cement and pozzolanicreactions at early ages, optimising their microstructures, without compromising late strength anddurability performances. In fact, these features could even be improved. Moreover, other uses arelow temperature concreting, precasting, shotconcrete, etc. Here, we focus on reviewing recent reportson calcium silicate hydrate seeding using commercially available admixtures. Current knowledgeon the consequences of nucleation seeding on hydration reactions and on early and late mechanicalstrengths is discussed. It is noted that other features, in addition to the classic alite hydration acceleration,are covered here including the enhanced ettringite precipitation and the very efficient porosityrefinement, which take place in the seeded binders. Finally, because the seeded binders seem to bedenser, durability properties could also be enhanced although this remains to be properly established.
