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 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...
