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
