Abstract

The invention relates to the technical field of building materials, and discloses a preparation method for floor ground insulation and leveling integrated self-leveling mortar. The preparation methodcomprises the following steps that S1, raw materials are obtained, wherein the raw materials include 21-32% of a cementing material, 55-75% of aggregates, 11-20% of a mineral admixture and 3-5% of anadditive; S2, all the raw materials including the cementing material, the aggregates, the mineral admixture and the additive are weighed in proportion and sufficiently dry-mixed; S3, the base surfaceof the floor ground is treated, and floating ash is cleared away. The self-leveling mortar has that advantages that the comprehensive mechanical properties are good, the fluidity is high, the maintenance time is short, the strength is high, the surface is flat, the shrinkage deformation is low, the binding strength is high, and the cost is low. After a day, the compressive strength can reach 7 MPa, and after 28 days, the compressive strength can reach 27 MPa, which fully meets the requirements of floor ground construction for the early strength of the self-leveling mortar. The initial fluidityis higher than 300 mm, and the fluidity changes little 20 minutes; by observing the newly mixed self-leveling mortar, no segregation and bleeding phenomena are caused, and the color is uniform.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing floor and floor thermal insulation and leveling integrated self-leveling mortar. Background technique [0002] In 2015, my country's building energy consumption accounted for about 20% of the national energy consumption, and building energy conservation is an important development direction in the future. In order to reduce the energy consumption of buildings, it is necessary to do a good job of thermal insulation measures for buildings so as to be truly warm in winter and cool in summer. At present, my country's building insulation measures are mainly focused on interior and exterior walls, roofs, windows, etc., and less is done on floor insulation. Studies have shown that floor heat dissipation accounts for about 20% of the overall heat dissipation energy consumption of a house. Insulated floors can effectively reduce floor heat dissipation an...
