Even during sealed curing, the relative humidity (RH) within a hardening cement paste may decrease. This self-created change in the RH (autogenous RH-change) may be so forcible that the cement paste cracks if the attached deformation is restrained. This Paper focuses on the influence of silica fume (SF) addition on autogenous RHchange in hardening cement paste. Continuous measurement of autogenous RH-change for more than 1½ years has shown it to be markedly increased by SF addition.
