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.

Concrete Compressive Strength Variation with Time

Jan 05, 2015 Variation of Concrete Strength with Time As per studies and researches, the compressive strength of the concrete will increase with age. Most researches were conducted to study the 28th-day strength of concrete. But in reality, the strength at 28th day is less compared to the long-term strength that it can gain with age.

Curing Concrete How Long it Takes & How To Cure The

Mar 02, 2010 But curing is more than that-it is giving the concrete what it needs to gain strength properly. Concrete strength depends on the growth of crystals within the matrix of the concrete. These crystals grow from a reaction between Portland cement and water-a reaction known as hydration. If there isn't enough water, the crystals can't grow and the
