The conventional practice is to use thermal insulation and sound insulation board and cast-in-place conventional concrete as leveling layer to meet the design requirements. In the implementation process, the existing technology uses the method of laying thermal insulation and sound insulation board and leveling layer, which will cause a large number of cracks and hollowing problems in the later stage, resulting in poor quality of building floor and short service life.
