Experiment on the Bending Performance of Sea Sand Concrete Beam under the Artificial Climate Environment
Through the experiment on the durability of sea sand concrete beam which is subject to climate conditions and indoor environment, the change of deflection, beam load-deflection curve, ductility and crack are studied. The results show: concrete beams that are mixed with sea sand are deteriorated by the chloride ion and their load-deflection curves as well as stiffness and ductility are reduced in different degree. But other beams that are mixed with desalinated sea sand are reduced not obviously. Otherwise, because of the bad environment accelerating degradation of the component mechanical performance and the sea sand desalination technology increasing the ability to resist environmental erosion, the component mechanical performance and the sea sand desalination technology take great influence to the component mechanical performance.
