FLEXURAL PROPERTIES OF REINFORCED POLYESTER CONCRETE MADE WITH RECYCLED PET

The flexural strength of steel-reinforced polymer concrete (PC) beams using unsaturated polyester resins based on recycled poly(ethylene ter ephthalate), PET, is reported in this paper. Investigation included mo de of failure, moment-curvature response, variation of neutral axis de pth with moments and the effect of tensile and compression steel reinf orcement on the strength and ductility of the beams. This evaluation i s not only important from the standpoint that resins based on recycled PET were used, but also because very few investigations have been don e in this area with steel-reinforced PC using virgin resins.
