Q1: 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 maximum aggregate size should not exceed 19 mm The properties of the
materials are as follows:

Cement : Type I, specific gravity = 3.15

Coarse Aggregate: Bulk specific gravity= 2.65; 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

Q4:Repeat Q 3: For slump value of 40mm. Compare the material cost.

Q5: Repeat Q 1: For fineness modulus of the fine aggregates 3.00. Compare the material cost.
