Filling type sand-free self-leveling mortar with ardealite as main raw material as well as preparation method and application of filling type sand-free self-leveling mortar

The invention discloses filling type sand-free self-leveling mortar with ardealite as a main raw material. The filling type sand-free self-leveling mortar is prepared from the following raw materials in parts by weight: 600-900 parts of compound ardealite powder, 80-600 parts of modified filler and 5-15 parts of an additive, the compound phosphogypsum powder is prepared by mixing alpha-type high-strength gypsum and mixed-phase gypsum according to a mass ratio of 1: (3-3.5). According to the invention, the industrial waste solid-ardealite can be effectively utilized, waste is turned into wealth, energy is saved, the environment is protected, and'carbon reaching peak and carbon neutralization 'is facilitated. The construction method is innovative, and the prepared filling type sand-free self-leveling mortar is high in flowability, can be automatically leveled after being paved on gravel, and is high in flexural and compressive strength after being maintained in the later period. 本发明公开了一种以磷石膏为主要原料的灌入式无砂自流平砂浆，由以下
