Compressive Strength of Concrete at 7 days and 28 days. Concrete continues to hydrate and to gain strength for years after it is poured. Concrete gains strength due to the chemistry of the hydration of the cement. Essentially the cement continues to hydrate while there is moisture available which it can simply take from the air in most cases.
