Because actual compression strength of concrete core is taken as 0.85 times of specified cylindrical strength. cylindrical strngth is given by 0.85fck As per your question :- 0.75 fck, Fck :- characteristic strength of concrete. Yani ki 0.75 × 25 ( 25 Grade of Concrete) 18.75 N/mm2 is individual strength but average strength not less than 0.85 fck 0.85 × 25 :- 21.25 N/mm2..
