[0040] The present invention will be further described in conjunction with the following examples:
[0041] The non-burning fly ash foamed sound-absorbing panel is a rectangular plate-like body 1, composed of a built-in frame 2 and a fly ash cement foaming agent 3. The built-in frame 2 is designed with 6 short steel pipes 5; the built-in frame 2 Lay flat on the mold 4, after the short steel pipe 5 in the built-in frame 2 is inserted into the column 6, the fly ash cement foaming agent 3 is used to pour the outside of the built-in frame 2, and the built-in frame 2 is completely embedded in the fly ash cement foaming agent 3. After the interior of the cement product, it is the semi-finished product of the non-burning fly ash foamed sound-absorbing panel; after the static curing treatment, the semi-finished product of the non-burning fly ash foamed sound-absorbing panel is taken out of the mold, and is cured and packaged according to the conventional curing methods of cement products ...
