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 13 and 17 and generally is less than 15, or the seven-day strength is normally between 60% to 75% of the 28-day strength and usually above 65% The cylinder that broke at 1980 psi is 66% of the specified 3000 psi According to ....
