Experiment on Bending Performance of Double Mixing HPC Concrete Beam under the Artificial Climate Environment

Abstract:

Through the experiment on HPC beam which is subject to artificial climate conditions and indoor natural environment, section strain, beam load-deflection curve, failure and cracks are studied. The results show: compared with ordinary concrete beam, the HPC beam which has been subject to artificial climate conditions has higher stiffness; the deflection amount and the width of crack of this concrete beam all fall in the confines of ultimate service state under use load; and the beam displays a better ductility in failure
