Which of the following statements are correct with reference to ensuring minimum shrinkage of prestressed concrete?1. The water-cement ratio and proportion of cement paste should be kept minimum to reduce shrinkage.2. Aggregates of larger size, well graded for minimum void, need a smaller amount of cement paste, and attendant shrinkage will be smaller.3. Harder and denser aggregates of low water absorptions and high modulus of elasticity will exhibit small shrinkage.
