The interfacial interaction between defoamer and air entraining agent was investigated by calculating the composition of mixed interfaces, the interaction parameter (β), and the free energy of additional adsorption and comparing the solution and hardened mortar performance of defoamer and air entraining agent in various proportions. The results show that compounding a suitable defoamer in a certain proportion into air entraining agent increases the interfacial free energy of the bubbles, resulting in a decrease in the stability of the foam and the air content of the mortar. The defoamer can also effectively reduce the air-void diameters and spacing factors of the hardened mortar, and improve the compressive strength of the mortar.
