Problems solved by technology

The construction thickness of conventional gypsum-based self-leveling floor mortar is usually 3-5mm, and the lightweight aggregates used are mostly low-strength ceramsite, thermal insulation perlite, etc., making its strength not enough to adapt to the long-term load-bearing and durability of the floor. Affected by wear and tear requirements, it can only be used as a surface decoration of the floor or as an auxiliary thermal insulation and sound insulation method used in conjunction with other thermal insulation materials

Abstract

The invention discloses sound insulation terrace mortar and relates to the technical field of building decoration materials. The sound insulation terrace mortar is technically characterized by comprising, by weight, 80-90 parts of alpha gypsum, 10-20 parts of volcanic rock lightweight aggregate, 0.5-3 parts of a water retaining agent, 0.5-3 parts of a retarder and 0-10 parts of cement; the densityof the volcanic rock lightweight aggregate is 200-500 kg/m<3>, and the strength of the volcanic rock lightweight aggregate is 1-5 MPa; the 28d compressive strength of the cement is higher than or equal to 52.5 MPa. The sound insulation terrace mortar has the advantages of being lightweight, great in sound insulation performance, high in compressive strength and capable of facilitating construction. The invention also correspondingly discloses a preparation method and application of the sound insulation terrace mortar. In addition, the invention also correspondingly discloses a sound insulation terrace construction method. The sound insulation terrace construction method comprises the steps of mortar modulation, filling of reinforced steel bars, scraping or spraying, caring and the like, and the construction process is simple and efficient; a constructed terrace has the advantages of good sound insulation effect, great heat preservation effect and excellent pressure resistance and water seepage resistance.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, more specifically, it relates to a sound-insulating floor mortar, a preparation method thereof, and a sound-insulating floor construction method. Background technique [0002] Insulation system is of great significance for building energy saving and noise reduction. Conventional building insulation systems are mainly divided into the following two categories according to the different insulation materials used: [0003] One is paving insulation boards, such as extruded polystyrene foam (extruded board), molded polystyrene foam (ordinary foam board), rigid polyurethane insulation board, mineral wool (rock wool), foam Glass, phenolic resin board, etc. In the prior art, the authorized notification number is CN207419940U Chinese patent disclosing the sound insulation, heat preservation and wear-resistant decorative floor system, which adopts the mode of heat insulation and sou...
