Concrete Compressive Strength  Know More
Concrete compressive strength does not depend on the full hydration of its cement particles but essentially on their closeness 10,11 In a concrete having a water/cement ratio lower than 042, hydration stops when there is no more water to hydrate the cement particl Below this critical value of 042, very fine cement particles can be fully hydrated but only the surface of the coarsest ones ....
