Concrete Mix Design - ACI Method 1. Concrete is required for counterweights on a lift bridge that will not be subjected to freezing and thawing conditions. An average 28-day compressive strength of 31 MPa will be required. Placement conditions permit a slump of 50 to 75 mm. at point of placement and a nominal maximum size aggregate of 25 mm. An investigation of economically available materials has indicated the following: Cement: ASTM C150 Type I (non-air entraining), SG = 3.15 Fine aggregate: Specular hematite, FM = 2.30, SG (Bulk SSD) = 4.95, Abs = 0.045% Coarse aggregate: Hematite, SG (Bulk SSD) = 4.65, Abs = 0.075%, dry-rodded weight = 2,600 kg/m³, nominal maximum size = 25 mm. Calculate the quantities of ingredients per cubic meter of concrete using ACI Method (absolute volume basis only for fine aggregates).

Concrete Mix Design-ACI Method The concrete will be non-air entrained since the structure is not exposed to severe weathering. Required average strength will be 24 MPa with slump of 75 to 100 mm. The coarse aggregate has a nominal maximum size of 37.5 mm and dry-rodded mass of 1600 kg/m. Other properties of the ingredients are: cement -- Type I with specific gravity of 3.15; coarse aggregate bulk specific gravity 2.68 and absorption 0.5 percent; fine aggregate-bulk specific gravity 2.64, absorption 0.7 percent, and fineness modulus 2.8.

To evaluate the effect of a certain admixture on the flexure strength of concrete, two mixes were prepared, one without admixture and one with admixture. Three beams were prepared of each mix. All the beams had a cross sectionof 0.15 m by 0.15 m and a span of 0.45 m. The third-point loading flexurestrength test was performed on each beam after 7 days of curing. The loads atfailure of the beams without admixture were 32.8, 34.5, and 31.7 kN, whilethe loads at failure of beams with admixture were 39.4, 35.6, and 35.0 kN.Determine:a. The modulus of rupture of each beam in MPa.b. The average moduli of rupture of the beams without and with admixture.c. The percent of increase of the average modulus of rupture due to addingthe admixture.
