Characteristics of the hydrated pastes including mechanical strength, degree of hydration, microstructure, pore structure, bound water and the chemical composition of C-S H are reported. 0.26 and 0.90 wt% of ZnO in C3S promote the hydration of C3S and the growth of C-S-H needles, resulting in a higher degree of hydration and enhanced compressive strength up to 7 days. Evidence from the XRD quantification and BSE-EDS indicates the change of the chemical composition of the C-S-H from the early age to later ages. BSE-EDS results further revealed the location of the incooperated Zn2+ in the C-S-H structure. Correlation of total heat release, MIP porosity and BET total pore volume to compressive strength/DoH were analyzed. Impact of ZnO amount on the hydration enhancement was also discussed.Construction & Building TechnologyMaterials Science, MultidisciplinaryMaterials Sciencec3shydrationznoc-s-hmorphologymicrostructuretricalcium silicatecrystal-structurecement hydrationpart izincimmobilizationpolymorphismdiffractionsolubilitymetalstext::journal::journal article::research article
