Question
Concrete is strongest when subjected to: O A) Tension O B) Bending O9 Torsion O D) Compression If a peak load of 250 kN was exerted on a 100 mm x 200 mm test cylinder, the compressive strength of the concrete is: OA) 28.6 MPa O B) 35.2 MPa O9 31.8 MPa O D) 32.4 MPa The approximate volume percentages of the principal components of a concrete mixture are: 6%, 11%, 41%, 26%, 16%. Which of the following lists matches the correct order of these main components? Start with the one at 6% and end with the one at 16%. O Air, Water, Coarse Aggregate, Fine Aggregate, Cement O Water, Coarse Aggregate, Fine Aggregate, Cement, Air O Air, Coarse Aggregate, Fine Aggregate, Water, Cement O Air, Cement, Coarse Aggregate, Fine Aggregate, Water Under ideal conditions, concrete should be batched and placed within after mixing, when retarding admixtures are not used. OA 90 minutes O B) 1/2 hour OC 4 hours O D) 120 minutes
