Study on degradation of macro performances and micro structure of concrete attacked by sulfate under artificial simulated environment

Based on the similarity principle, the similarity criterion of concrete attacked by sulfate corrosion was deduced, and the change laws of concrete sulfate attack under natural condition and artificial simulated environment were revealed. The variations of micro structure, morphology and compositions of concrete before and after sulfate attack were investigated by Environmental Scanning Electron Microscope (ESEM), Mercury Intrusion Porosimetry...
