Simply stated, no structural concrete can be specified with a strength less than 2500 psi. Other properties of the concrete can be significant for concrete exposed to freeze-thaw conditions, sul-

### Compressive Strength % of 28-day moist-cured

2005-9-21 “Usually your 7-day is 75% of your 28-day strength. Isn't this chart a standard?” The chart is not standard. Say a mix has a quantity of flyash substituted for cement. This mix might reach only 50% at 7 days and only 90% at 28 days. Every mix cures and gains strength at different rates.

### Rate of Strength Gain of Concrete Concrete Strength

2017-2-1 Strength can be defined as ability to resist change. One of the most valuable properties of the concrete is its strength. Strength is most important parameter that gives the picture of overall quality of concrete. Strength of concrete usually directly related to cement paste. Many factors influence the rate at which the strength of concrete increases after mixing.

The strength of concrete is measured in PSI (Pounds per Square Inch). As PSI increases, so do strength and price. Typically, concrete strength ranges from 2,500 PSI to 5,000 PSI, though there are stronger mixes for specialized applications. For many home projects, 2,500 to 3,000 PSI is enough to get the job done. Learn More

### How Thick Does Concrete Need to Be to Hold Up

Structural concrete work is planned to bear loads, or hold weight, but transfer the weight to the soil base beneath the structure. The thickness of concrete is an important factor in load-bearing strength, but to conserve resources and avoid over-building, other factors are also taken into consideration.
