Question 3 (Prof. Fevziye Akz Group) :(30 marks) For an industrial structure, 360-dose concrete will be produced using the materials which their properties are given in the Table 3. Table3. Material B (kg/dm") (kg/dm) A1 A2 A3 Cement 1,60 1,57 1,57 1,15 2.50 2.50 2.56 3,10 a) Calculate the amount of theoretical material quantities required for 1 m of fresh concrete with an air gap of 1.5%, using the mix ratios (a1, a2, a3) of the aggregates and the fineness module (FM) of the mixture you set in Question2. (a1=292 a2=3000 a3=547 FM=3.94 ) b) Calculate the amount of water from the correlation below, Wwater=30(10-FM) c) Since the desired slump in the 10 liter test mixture is provided with 1.98 It of water and the unit weight of the fresh concrete is 2.325 kg/dm3; Calculate the actual amount of materials required for 1 m3 of fresh concrete. d) According to the test of 15/30 cm sized cylinder samples, concrete is produced on the 28th day, with an average load of 460 kN. The concrete class is C18, C20, C25 or C30 ?
