Answer Posted / himanshu sekhar pradhan
Actuall all grade of concrete design upon its target
strength. Then for M20 we have to design the mix on
26.6N/mm2 and all grade of concrete should achive its 60 -
75% strength in 7days. Then the actual strength of M20
grade of concrete at 7days should be 17 -20 N/mm2.
Otherwise there is chance of fail.
