Compressive Strength of Concrete - CivilWeb …

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. Therefore there is a problem with deciding exactly ...

Generally, concrete compressive strength decreases with an increasing specimen section size. Meanwhile, a decreasing rate remains almost constant beyond a certain size limit. Cube compressive strength is normally higher than that measured from a cylinder, but the effect of specimen shape on the size effect is somewhat indecisive [3].
