CRACKING IN PRESTRESSED CONCRETE BEAMS DUE TO ASR IN CABLE GROUT

The manifestation of cracking observed in prestressed concrete beams has been explained as due to ASR phenomenon occurring within the cable ducts. Using finite element modelling technique, it has been shown that the macro-cracking in concrete will initiate inside the beam and progress to the outer surface. The cracking not only increases the risk of corrosion to prestressing steel but also alters stress levels and deformation characteristics. (A) For the covering abstract see IRRD 871351.
