Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days.

The compressive strength is the ability or the strength of the concrete to withstand the compressive forces or stresses without getting crushed or destroyed. Crushing strength is the ultimate withstanding ability (Yield point) of concrete up to the point of the concrete getting fractured or crushed under the influence of the applied force.

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%.
