Answer / sathish

eventhough we did everything correctly in the mix design
there may be a deviation from our manual calculation to the
field hence we need different samples for the cube testing
and the average values of the different samples serves as
the evidence of our work.the deviation value which i said
will occur due to several reasons such as improper mixing,
water content, properties of cement, sand and aggregate and
even due to properties of water.
