This research was conducted to evaluate the concrete acid corrosion in the superficial soil layers of urban area at the higher ground temperature owing to the urban heat island effect.The compressive strength properties of concrete specimens

which were held in the situation of temperature 5℃

20℃and 40℃

acid concentration 0%

5%and 10%

and erosion time 30 d and 90 d were studied.And the mechanism of concrete acid corrosion and the urban heat island effect on the concrete strength in superficial soil layers for Nanjing area was analyzed.The test results indicate that the coefficient of corrosion of concrete specimens increases with the increasing of the temperature;and the temperature has an increasingly powerful influence on the coefficient of corrosion with higher acid concentration.Under the situation of sulfuric acid concentration 10%and immersing time 30 d

the coefficient of corrosion of concrete specimen reaches 45.21%at the temperature 40℃

which was almost twice of the corrosion coefficient at temperature 5℃. In other words

the coefficient of corrosion increases 0.64%with the rising 1℃of the environment temperature. The research achievement has a clear meaning to reduce the urban heat island effect in geotechnical engineering.
