Answer: D. All the above
Shrinkage in concrete can be reduced by using low water-cement ratio, less cement in the concrete and proper concrete mix.
Solution
Shrinkage in concrete mainly depends on the following factors:-
- Water-cement ratio- If the water-cement ratio increases, then shrinkage of concrete increases and vice versa.
- Time- The rate of shrinkage rapidly decreases with time.
- Type of aggregate- The shrinkage rate decreases with the increase in the aggregate size.
- Environmental condition- Shrinkage occurred due to the drying condition of the atmosphere.
- Admixture- With the addition of accelerating admixture like calcium chloride, shrinkage of concrete increases.
Shrinkage in concrete also depends on some other factors like type and quantity of cement, the strength of concrete, methods of curing etc. Shrinkage in concrete can be reduced by using low water-cement ratio, less cement in the concrete and proper concrete mix.
