The rapid sulphuration test of concrete in typical industrial environment was carried out. Variations of concrete sulphuration depth with water-cement ratio， temperature and SO₂ volume fraction were studied. The prediction model of concrete sulphuration depth in typical industrial environment was established. The sulphuration mechanism of concrete was analyzed by means of scanning electron microscope （SEM） and X-ray diffraction （XRD）. The results show that the sulphuration depth of concrete increases with increasing sulphuration age. When the temperature is 50 ℃ and the SO₂ volume fraction is 0.9%， the sulphuration depth of concrete with a water-cement ratio of 0.57 reaches 5.27 mm at the age of 20 days. The sulphuration product is acicular crystal ettringite at the initial stage of sulphuration， and a large number of plate crystal gypsum is formed in the specimen at the age of 20 days.
