Construction method for reducing surface bubbles of aluminum alloy formwork concrete

The invention discloses a construction method for reducing surface bubbles of aluminum alloy formwork concrete. The construction method comprises the following steps that Tween20, sodium dodecyl sulfate and water are prepared into a first mixed solution, and simethicone and sorbitan monolaurate are uniformly stirred until the mixed solution is milky white to prepare a second mixed solution; the first mixed solution is slowly added into the second mixed solution, adding is carried out while stirring until the first mixed solution is completely added, then a compound modified additive is added,uniformly stirring and mixing are carried out to obtain a bubble eliminating release agent, the bubble eliminating release agent is directly sprayed on the surface of a formwork, and then concrete ispoured; and the surface tension of foam is changed through the bubble removing release agent, so that small bubbles are gathered into large bubbles, the bubbles are broken to achieve the defoaming effect. The preparation metho
