A concrete for a weave breaker is to be designed at a w/c ratio
of 0.45.
A maximum size of aggregate of 25 mm was used hence a water content
of 200 kg/m3 (with 2% air) was required to achieve satisfactory
workability.
Both the coarse and fine aggregate conform to the grading
requirements of ASTM C33.
The fine aggregate having a fineness modulus of 2.4, and an
absorption of 2%, a BSG (SSD) of 2.6, whereas the coarse aggregate
have a bulk density of 1500 kg/m3; an absorption of 3% and a BSG
(SSD) of 2.50.
The moisture content for both aggregate is 2%. Compute mixture
proportions (in kg/m^3) before and after moisture corrections
following ACI procedure.

A concrete column is to be designed at a w/c ratio of 0.40 in an
environment where an aggressive F/T persists. A maximum size of
aggregate of 19 mm was used. A slump of 30 mm was required to
achieve satisfactory workability. Both the coarse and fine
aggregate conform to the grading requirements of ASTM C33. The fine
aggregate having a fineness modulus of 2.8, and an absorption of
2%, a BSG (SSD) of 2.5, whereas the coarse aggregate have...

A concrete mix is required for reinforced concrete wave breaker
at seashore where frequent mild freezing and thawing is
dominant.
A specified compressive strength of 25 MPa is required at the age
of 28 days, and the size of the section and reinforcement dictate
using a maximum aggregate size of 19 mm.
The company had no history of testing concrete used.
The coarse aggregate meets the ASTM grading requirements. It has
absorption of 2%, a BSG (D) of 2.70 and...

A concrete mix was designed for a concrete road pavement (i.e.
heavy mass concrete). A 28-day strength of 26 MPa is required. The
exposure classification for durability purposes is C. One hundred
laboratory test results on the controlling mix show a standard
deviation of 5.3 MPa (k=1.65). The density of crushed coarse
aggregate is 2850 kg/m3 and its dry rodded density is
1600 kg/m3 and the maximum size to be used is 10 mm. The
specific gravity of fine aggregate...
