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.

Design a concrete mix using ACI Method required for an exterior
column to be located above ground level in an area where it will be
wet and subjected to substantial freezing and thawing. The concrete
is required to have an average 28-day compressive strength of 30
MPa. For the conditions of placement, the slump should be between
25 and 100 mm. The column is 300 mm square with a minimum clear
space for aggregate of 50 mm. The properties of...

Using the absolute volume method, a colleague started a mix
design for a simple concrete foundation in a mild climate and got
through Step 5 and has asked you to finish the work. They have
already determined the mix needs:
• a w/c ratio of 0.45
• a 2” slump
• 1830 lb of gravel in the oven dry conditions,
• and 3.5% air provided by air entrainer.
The available gravel (coarse aggregate) is subangular with a NMSA =
3⁄4”....

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

a. Design a concrete mix for construction of a water
tank using ACI Committee 211.1-year 1991. The specified design
strength of concrete is 30 MPa at 28 days. Standard deviation can
be taken as 4 MPa. The specific gravity of fine aggregate and
coarse aggregate are 2.65 and 2.7 respectively. The dry rodded bulk
density of the coarse aggregate is 1600 kg/m3 and the fineness
modulus of fine aggregate is 2.80. Ordinary Portland cement (Type
I) will be used. A...
