Do you know differenence between design mix and nominal
mix?
Answer Posted / adersh v s
Nominal mix means mixing cement, fine aggregates and coarse
aggregates based on volume
Eg: 1:2:4 mix means mixing one volume of cement with two
volumes of sand and four volumes of coarse aggregates.This
is normally used when the the volume of concrete work to be
done is less.
Design mix is a trial and error procedure.Here the
characteristics of the aggregates cement and water used for
concrete is first analysed and these are mixed in ratio of
their weights and is tested for the design strength.Here
better quality control is maintained and also the
unnecessary wastage of materials is less.
A Design mix is that mix which uses minimum quantity of
components to attain the designed strength of concrete
whereas in a nominal mix attanining the characteristic
compressive strength is the criteria of mix proportioning.
