Abstract

The difference between normal and polymer concrete not contain a hydrated cement phase. In present work, behavior and strength of thepolymer concrete composite castellated beam withdifferent openings shape by experimental approach are investigates. Ultimate load strength capacity and deformations of the composite beams specimens are explorations. Ultimate load strength capacity and deformations of the composite beams specimens are explorations. Different parameters are considered such as shape of openings for the castellated beam. Test results showed that the hexagon opening shape gave more strength capacity and less deflection. The full interaction gave more strength capacity and less deflection.It was found that the percentage of increase in ultimate load for the specimen (Geopolymer composite castellated beam with opening 35% for Hexagonal shape with full interaction ) was about (83%) for the reference specimen (Control Composite Castellated), as well as the specimen (Geopolymer composite castellated beam with opening 70% for Hexagonal shape with full interaction), it gave more durability than the reference specimen (Control Composite Castellated) with 48%. As for the fourth model, (Geopolymer composite castellated beam with opening 70% for Rectangular shape with full interaction) gave higher durability than the reference specimen by 24%.
