engineering recuitment PPSC JE Civil Mock Test 2022 Reinforced Concrete Structures Prestress Concrete
For pre-stressed structural elements, high strength concrete is used primarily because
1
Both shrinkage and creep are more
2
Shrinkage is less but creep is more
3
Modulus of elasticity and creep values are higher
4
High modulus of elasticity and creep values are lower
