QI: Prepare mix design for given data • The 28-day compressive strength should be 34 MPa, The slump should be between 75 mm and 100 mm and the masimum aggregate size should not exceed 19 mm The properties of the materials are as follows • Cement : Type l, specifie granity - 315 Coarse Aggregate: Bulk specifik gravity- 265: absorption capacity -0.5%: dry-rodded unit weight - 1605 kg'm3, surface moisture - 1% Fine Aggregate: Bulk specific gravity- 2.60; absorption capacity - 1.1%; fineness modulus - 2.70; surface moisture -3% Q2: Repeat Q 1: for max. aggregate size of 37.5 mm. Compare the material cost. Q3: Repeat Q 2: for compressive strength of 41 MPa. Compare the material cost
