Answer / mohammed aaqhil inayath
It depends on the grade of concrete you use. If it is M25
then 65% of the total strength(i.e. 65% of 25 n/mm2)

Answer / saumik mallick
After 7 Days the test result will be 67% of the Target Mean
Strength and after 28 days the test result will be 100% or
more than target mean strength.
i.e Target mean Strength (fck')= fck+(1.65*S)=
25+(1.65*5)=33.25 Mpa.
