After curing for 28 days, 15% to 20% of the hydrated portland cement paste is calcium hydroxide. Therefore, there is large amount of calcium hydroxide normally available that can be converted to C-S-H. All that is needed to make this happen is a source of silica. Add some fly ash to your portland cement before hydration for this purpose.
