Behavior of Post-Tensioned Polymer-Impregnated Concrete Beams
This study was conducted to investigate the behavior of post-tensioned polymer-impregnated concrete (PIC) beams. Three major areas of behavior were studied by experimental and theoretical analyses: flexure, shear, and time-dependent deflections. Test results were compared to values calculated according to ACI Standard 318-71 and to results from numerical analyses for inclined cracking and ultimate shears, moment capacity, and tendon stress increase. The beams were dried to remove the moisture from the concrete voids, impregnated with the monomer system, and polymerized by thermal-catalytic methods. The tendons were stressed to about 70 percent of the ultimate strength prior to the testing. Nineteen simply-supported beams with I-shaped cross sections were tested using two symmetrically placed concentrated loads.
