3. TRANSFER LENGTH

The transfer length of prestressing strands at the ends of the girders was determined by measuring the strains in a ‘‘strain gage bar” (SGB) embedded in each girder. Bars used in girders C4, D4, and B4 had eight strain gages, while the bar used in girder A4
had nine strain gages. The gages were read with a standard strain gage indicator after the concrete had cured and just before detensioning, in order to obtain the initial readings. The gages were then read immediately after detensioning. The change in strain for each gage is plotted in relation to its distance f..................[:=> Show Contents <=:]

High performance concrete (HPC) is defined as a concrete mixture which posses high workability, high strength, high modulus of elasticity, high dimensional stability, low permeability and resistance to chemical attack.
There is a little controversy between the terms “high strength concrete” and “high performance concrete”. High performance concrete is also a high strength concrete but it has a few more attributes specifically designed as mentioned above. It is there for logical to describe by the more widely embracing term “high performanc..................[:=> Show Contents <=:]
