Relationship Between Seven- and 28-Day Strengths| Concrete ...

Concrete, by Mindness and Young, gives a general rule: The ratio of 28-day to seven-day strength lies between 1.3 and 1.7 and generally is less than 1.5, or the seven-day strength is normally between 60% to 75% of the 28-day strength and usually above 65%.
