Question
Design a concrete mix for construction of an elevated water tank.
Required Slump = 3”. Maximum Size of Aggregate is 19mm.
The specified design strength of concrete is 30 MPa at 28 days measured on standard cylinders.
The specific gravity of FA and C.A. are 2.65 and 2.7 respectively.
The dry rodded bulk density of C.A. is 1600 kg/m3, and fineness modulus of FA is 2.80.
Ordinary Portland cement (Type I) will be used. S.G. = 3.15
C.A. is found to be absorptive to the extent of 1% and free surface
