Answer ALL Questions
Physical and mechanical properties of civil engineering materials, their behaviour and characteristics
in design and construction works. Answer below questions using your own words and understanding.
(a)
(i)
Design a concrete mix for the following given data:
A mean 28-day compressive strength (measured on standard cubes) of 45 MPa
Slump = 40 mm, Uncrushed aggregate with maximum size of 20 mm
Specific gravity of aggregate = 2.64
Fine aggregate passes through the 600 µm sieve = 48%
No air entrainment required, ordinary Portland cement to be used.
