Design a concrete mix for the superstructure of a
building using DoE mix design method requiring a characteristic
strength of 40MPa at 28days and a slump of 30-60mm. The materials
available are ordinary Portland cement, and uncrushed fine and
coarse aggregates of specific gravity of 2.65. The maximum nominal
size of coarse aggregate is 10mm and fine aggregate confirms to the
grading zone III. Neglect the effect of standard deviation and
other factors.

Why concrete mix proportions need to be
designed? After completing the design mix process,
explain what are the next steps to be done?
If the same concrete mix proportions calculated in
(a) is to be used for application near marine environment or in
heavy industrial area, suggest with justification
the possible modification that can be
done.

Design a concrete mix for reinforced concrete beams of a
structure. The structure is located in a locality wherein water has
excess of chlorides in it. Required average compressive strength of
concrete has been determined to be 4700 psi. Beams have
cross-section of 9 in. x 21 in. reinforced with 4 # 6 bars.
Reinforcement has a concrete cover of 1.25 in. and there is a clear
space of 1.0 in. between form surface and steel bars. Fine
aggregate has...

Example of Mix design proportion calculation
• You need to design the mix proportion of a grade 40 for a column
with workability of 50
mm slump and w/c not more than 0.55. The maximum size of gravel
aggregate is 10 mm
and the fine aggregate is quarry blast sand. The moisture content
of the aggregate is as
follow:
• The gravel aggregate is in moist condition with moisture content
of =3.5%, dry density
= 1700 kg/m3
• The sand...
