05/07/2017  High strength concrete has extraordinary rheological properties and hence the development of strength is more complex in nature majorly due to the physiochemical effects of the pozzolans that would be added in most times to achieve such high strength [1-4]. Some good attributes of high strength concrete includes: high workability, high modulus of elasticity, high density, low

The use of high-strength concrete for pretensioned con-crete girders is common because of its engineering and economic benefits. As concrete strength and prestress level increase, accurate estimation of long-term prestress loss becomes more important. Overestimation could lead to ex-cessive prestress and camber, while underestimation could lead to bottom fiber cracking under service
