A process method for a building floor backfill spacer with foamed concrete as the bottom layer of the building floor backfill spacer. The method comprises: filling the ground with foamed concrete to form a foamed concrete layer (1); treating the surface of the foamed concrete layer (1), and applying composite mortar on the treated surface of the foamed concrete layer (1) to form a high-strength solidified protective layer (2). Also disclosed is a structure of the building floor backfill spacer. The structure of the building floor backfill spacer comprises the foamed concrete layer (1), a treating interface layer formed on the treated surface of the foamed concrete layer (1), and the high-strength solidified protective layer (2) formed by the composite mortar. The structure of the building floor backfill spacer is light and capable of insulating sounds, protecting the environment and saving energy, and can effectively avoid the phenomena of cracking, dusting, hollowing and the like. |
