| Abstract: | A study has been made of the influence of calcium salts, as set-controlling admixtures, on the hydration of tricalcium silicate. It is found that some admixtures modify the morphology of C-S-H gel and for calcium hydroxide. Changes in capillary porosity distribution can be correlated with changes in the morphology of the outermost C-S-H gel. It is concluded that capillary porosity, as controlled by the degree of hydration is still the dominant factor controlling tensile strength. |
