Abstract:
In order to investigate the relationship between the microstructure of hydrated cement paste and its effective performances, based on the Jennings-Tennis (J-T) model on distinction of two kinds of calcium silicate hydrate(C-S-H), quantitative formulas for volume fraction of hydrated products in Portland cement are given. The harden cement paste with water to cement ratio of 0. 23, 0. 35 and 0. 53 are used to validate the formulas proposed and the results are compared with those obtained by Powers model. It is shown that the volume fraction ratio of low density C-S-H to high density C-S-H in hydrated cement paste with water to cement ratio of 0. 23, 0. 35 and 0. 53 are 0. 24, 0. 54 and 3. 24, respectively. The volume fraction of capillary porosity and unhydrated cement is in agreement with that from Powers model, which verifies the reasonableness of the calculation formulas proposed.
