Abstract

The effects of air entraining agent on the durability of high performance concrete based on sulphoaluminate
were studied. The effects of air entraining agent on durability (frost resistance, carbonization resistance, etc.) of
sulphoaluminate cement-based concrete were studied. And the mechanism was analyzed by SEM and pore
structure analysis. The results show that the frost resistance of high performance concrete based on
sulphoaluminate cement increases gradually with the increase of entraining agent in microscope environment.
However, under the microscope environment, with the increase of the amount of air entraining agent, the
carbonation resistance of high performance concrete based on sulphoaluminate cement decreases gradually.
