Construction method of matched thick paste type cement-based self-levelling terrace for assembled building

The invention discloses a construction method of a matched thick paste type cement-based self-levelling terrace for an assembled building, and belongs to the technical field of the assembled building.The method comprises the following steps of (1) cleanly cleaning the surface of a floor before construction; coating an aqueous interface agent; and preparing the thick paste type cement self-levelling construction after the aqueous interface agent is completely dried; (2) preparing slurry according to the water-to-material ratio of 0.15 to 0.21; performing uniform stirring; then adding aggregates; and pumping the mixture to the construction floor after the uniform stirring; (3) after the mixture reaches the construction floor, performing construction surface casting by moving a pump pipe; and (4) uniformly spreading the mixture by construction personnel wearing spiked shoes by using a big tooth rake according to the elevation projected by a laser leveling instrument so that the materialrealizes the self leveling
