### The 28-Day Myth - National Precast Concrete Association

Oct 28, 2013 · It is estimated that concrete reaches 75% of this 28-day compressive strength in seven days, and its strength will remain stable or even increase over time (2). A specific ratio can be determined for each specific mix design and curing process to fine-tune this arbitrary age so that the mix design dictates the 28-day compressive strength.
