LOSS OF PRESTRESS IN LIGHTWEIGHT CONCRETE CONSTRUCTIONS /IN RUSSIAN/

RESULTS ARE COMPARED OF TESTS CARRIED OUT ON AUTOCLAVED PRESTRESSED CONCRETE MEMBERS WHICH WERE PREPARED WITH LAYERS OF ORDINARY CONCRETE AND EXPANDED CLAY CONCRETE. THE NEED FOR TAKING INTO ACCOUNT THE DIFFERENCE IN SHRINKAGE BETWEEN VARIOUS TYPES OF CONCRETE IN ORDER TO DETERMINE THE LOSS OF PRESTRESS IN THE REINFORCEMENT IS EMPHASIZED. THE BENEFICIAL INFLUENCE OF A SEALING COAT FOR PROTECTING CONCRETE STRUCTURES IS STRESSED: IT REDUCES THE LOSS OF PRESTRESS CAUSED BY CREEP IN LIGHTWEIGHT CONCRETE TO A THIRD OF WHAT IT WOULD HAVE BEEN AND THE LOSS OF PRESTRESS DUE TO SHRINKAGE IN HIGH-STRENGTH CONCRETE TO ONE TENTH. /LCPC/RRL/
