Experiment Study on Shear Behavior of Polymer Concrete Beams

폴리머 콘크리트의 보의 전단거동에 관한 실험적 연구

This research focuses on producing a cheap polymer, and also experiments for marking with the high strength polymer concrete structures. At present only a few tests on shear behavior in polymer reinforced concrete beams(PRC) have been reported. In the current experiments, the reinforced concrete beams with polymer fraction are investigated. The beams in this study are supported by conventional stirrups at appropriate intervals and they are designed to take static loads. The strength of beams are measured and the behavior of beams under each loading are oh served in order to determine some advantages of adding polymer to reinforced concrete beams. The static testing data consist of load, displacement, and strain at specified reinforcement locations, and the support displacement In the static tests, it has been observed that the beams fail in the same way as RC. However, it is observed to he rather weak in impact, hut it can he said that its increase of strength and excellency of repairing are verified. Consequently this work strongly suggests that the steam-curing or the air-curing or the air-curing must be performed to increase the strength.
