Abstract
The pore structure ofβ‐C2S, C3S, and portland cement pastes was investigated using mercury porosimetry and H2O and N2 adsorption. The β‐C2S had more total macro‐ and mesoporosities than C3S and portland cement pastes of a similar degree of hydration. C3S and portland cement pastes had similar total porosities but differed in the porosity size distribution. In the mesopore range, the various test methods gave different results. These differences are discussed on the basis of the various models proposed for cement paste. It is shown that shrinkage could be correlated with the volume of pores <0.03 μm, but not with total porosity.Keywords
