What is Wet Basement? How can we avoid it?
First of all 28 days strength is the definition of compressive strength. So it's obvious to test concrete on 28 days for strength. Concrete reaches 99% of its full potential strength in 28 days and 28 is also a round figure (4 weeks). Hence, it is chosen for the definition. Now, 3, 7, and 14 day areRead more
First of all 28 days strength is the definition of compressive strength. So it’s obvious to test concrete on 28 days for strength. Concrete reaches 99% of its full potential strength in 28 days and 28 is also a round figure (4 weeks). Hence, it is chosen for the definition.
Now, 3, 7, and 14 day are both round figure in terms of percentage of strength development and also round figure in weeks. 
The reason for testing concrete before 28 days on these days as well is that suppose the concrete strength falls fairly inadequate on let’s say 7 or 14 days. Then, the concrete may straight away be discarded or another mix design be made. Or else, better curing can be done. This will save time, money and effort. That’s why generally three tests are done during the 28 day cycle.

The presence of moisture due to various reasons is simply the meaning of the wet basement. In the area of the basement, efflorescence will occur. Efflorescence means the deposition of white powder on the surface due to the presence of alkalies.
