The test results shall be average of 3 specimens. Individual variation should not be more than +15%
Compressive Strength: The mean strength from any group of 4 consecutive test results shall be as below:
For M:15 - it shall be > 1= Fck+  
0.825 x S.D.  
Or
fck+ 3 N I mm2 whichever is Greater

Provided individual test results shall be > /= Fck-
3 N I mm2

For M: 20 or Above –
It shall be >/=  Fck + 0.825 x S.D.
Or
Fck + 4N /mm2
whichever is Greater
Provided individual test results shall be > /= Fck+
4 N I mm2
Note: In case S.D. is not established then assumed S.D. as per Table-8 shall be considered.
