Theshrinkageofthecementpastewithlowwater-cementratioatdifferentrelativehumiditywasobservedandanalyzedwithESEManddeformationmaptechnique.ThecrackmorphologywasobservedwithdifferentmagnificationwithSEMandFESEM,andtheformationofthecrackwasobservedwithAFMbetweentwoC-S-Hnanoparticles.Theobservationbymultitechniqueatmultiscaleindicatedthattheshrinkagewasincreasewiththedecreaseofthehumidityduetotheincreaseofthepressureofthecapillarypressure,themorphologyofthecrackinsmallerscalewassimilartothatinthebiggerscale,thesmallercrackdistributedinthelatticeworkofthebiggerones,andthecrackpropagatedalongthegapbetweentwonanoparticlesofC-S-Hwithweakerbonding.
