How can I calculate the Compressive strength of cubes after 28
days of curing?Is there any formula or ration ?
Answer Posted / done
Seriously I can't believe it. The formulas u r giving is for therotical value of compressive strength . u can calculate that value without making any cube. But for 28 day compressive strength there is machine which applies increasing load untill cube gets failed that load per unit area is nothing but compressive strength. Nowadays we don't have to wait for 28 days as these test are done after 2-3 days on labs n they put these result n their software which will ultimately give the final compressive strength
