Per §5.3.1, the SINGLE most important factor governing the workability of fresh concrete is:
AThe compressive strength target
BThe water content of the mix
CThe age of the cement bag used
DThe colour of the coarse aggregate
Answer & Solution
Correct answer: B. The water content of the mix
1. §5.3.1 opens: 'The single most important factor which governs the workability is the water content.'
2. The same paragraph warns that arbitrarily adding water reduces strength and may cause segregation and bleeding
if more water is added, a proportional cement increase is needed to keep w/c constant.
