2/3 OF THE 28 DAYS STRENGTH IS THE STRENGTH OF 7 DAYS .
RELATION WILL NEVER GET ALTERED DUE TO VARIOUS WATER CEMENT
RATIOS . IF THE WATER CEMENT RATIO CHANGES 28 DAYS STRENGTH
ALSO CHANGES ......................FINALLY AGAIN 7 DAYS
STRENGHT IS 2/3 OF THE FINAL 28 DAYS STRENGTH AFTER THE
WATER -CEMENT RATIO IS ALTERED

Answer / ramir v. agustin
In concrete testing samples aged in seven days should yield
70 percent of the specified strengt requirment and 28 days
sample should yield 100 percent of the compressive strength
required.Water cement ratio and amount of cement plays a
very important role in the production of good concrete.The
stregth of concrete depends on its water cement ratio
