The present invention provides a method for producing cellular concrete without using a special mixer or additional equipment, in which the distribution of bubbles is uniform, the generation of coarse bubbles is suppressed, and the density difference between the upper side and the lower side in the foaming direction is small. The present invention relates to a method for producing cellular concrete obtained by foaming an aqueous slurry obtained by mixing a concrete raw material mainly composed of cement, an aluminum metal powder, a surfactant, and water. . In the present invention, the aluminum metal powder and at least a part of the concrete raw material are mixed in advance to prepare a mixed powder, and then an aqueous slurry is prepared. A homogeneous aqueous slurry can be produced in a shorter time than mixing only the metal powder into the aqueous slurry raw material. [Selection figure] None |
