Concrete Curing Time Chart – The 7 To 70% Rule

This is because concrete will reach 70% of its overall strength after 7 days after the concrete being placed. We can see that in the first 7 days of concrete being placed and finished, the concrete will reach 70% of its potential strength. Over the next 21 days, the concrete should reach 90% of its overall compression strength, and the last 10% ...
