Compressive Strength Of Concrete For 7 Days Cylinder

7-day compressive strength test results are often used to monitor the gain of early strength and they are estimated to be about 64 to 70 of the 28-day strength.As such, it serves as a warning signal to both concrete producers and contractors should the 7-day compressive strength test results are far less than 75 of the 28-day strength.

Concrete Compressive Strength An Overview

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 watercement ratio lower than 0.42, hydration stops when there is no more water to hydrate the cement particles.Below this critical value of 0.42, very fine cement particles can be fully hydrated but only the surface of the coarsest ones.
