Problems solved by technology

[0003] The traditional wall plastering of aerated block masonry is to use mortar made of cement and yellow sand for plastering and leveling, and then apply ordinary putty. The disadvantage is that the putty material and the wall are not directly bonded, but A layer of mortar material is sandwiched, because the mortar material is easy to spill, pollute the environment, and waste materials; and the mortar layer is prone to cracking, hollowing, and labor-intensive materials; in addition, ordinary putty has low strength, relatively small adhesion, and is easy to crack. Easy to fall off in wet environment

Embodiment 1

[0007] Embodiment 1, the construction method of special putty-based mixture for aerated block masonry application: the first step, wall surface treatment, physical treatment of the uneven part of the wall body, but not leveling with filler, wetting with water; the second step , Prepare a special putty-based mixture and prepare a special bucket with a volume of 50 liters. According to the percentage by weight, put putty powder 67.8%, cement 5.8%, gypsum powder 7.0%, cast stone powder 2.0%, talc powder 4.8%, diatomite 2.7%, water 3.9%, flexible adhesive glue 1.0% into the special barrel in sequence %, anti-cracking additive 5.0%, stir with a portable electric mixer for 3-5 minutes to form a uniform paste, let it stand for 8 minutes, stir again, and then it can be used; the third step is to fill and build with a special putty-based mixture Body mortar joints; the fourth step is to apply a special putty-based mixture at the junction of the concrete and the masonry wall, and paste ...

Embodiment 2

[0008] Example 2, the construction method of the special putty-based mixture for aerated block masonry application: the first step, wall surface treatment, physical treatment of the oversized concave and convex parts of the wall, but not leveling with fillers, wetting with water; the second step , Prepare a special putty-based mixture and prepare a special bucket with a volume of 50 liters. According to the percentage by weight, put 67.4% of putty powder, 6.0% of cement, 7.6% of gypsum powder, 1.9% of cast stone powder, 4.9% of talcum powder, 2.5% of diatomaceous earth, 3.7% of water, and 1.2% of flexible adhesive glue into the special barrel in sequence. %, anti-cracking additive 4.8%, stir with a portable electric mixer for 5 minutes to form a uniform paste, let it stand for 10 minutes, then stir again, and it can be used; the third step is to fill up the masonry ash with a special putty-based mixture The fourth step is to apply a special putty-based mixture at the junction ...

Abstract

The invention discloses a construction method of a special putty-based mixture for coating an aerated block masonry. The construction method comprises the following steps: (1) a concave-convex part of a wall is physically treated, and is moisturized by water; (2) the special putty-based mixture is prepared; putty powder of 62.2-73.8%, cement of 4.8-6.5%, gypsum powder of 6.6-8.0%, cast stone powder of 1.5-2.3%, talcum powder of 4.2-5.5%, kieselguhr of 2.3-3.0%, water of 3.4-4.0%, flexible adhesive glue of 0.9-1.5% and crack resistant additive of 4.2-5.3% are added in a special barrel of 50 L in percentage by weight in sequence, are stirred for 3-5 minutes, and are subjected to still standing for 5-10 minutes; (3) a masonry mortar joint is filled by the special putty-based mixture; (4) a joint of the concrete and a masonry wall surface is filled by the special putty-based mixture, and is bonded with alkali-resisting glass fiber gridding cloth; (5) the special putty-based mixture of 4-6 mm is pressed into the alkali-resisting glass fiber gridding cloth; (6) the special putty-based mixture is used for leveling; and (7) general putty is coated once; and emulsion paint is brushed for two times. The special putty-based mixture is high in strength and great in adhesive force, and is directly combined with the aerated block masonry without being deformed and dropped.

Description

[0001] Technical field [0002] The invention is suitable for building walls, especially for the construction method of the special putty-based mixture for aerated block masonry smearing. Background technique [0003] The traditional wall plastering of aerated block masonry is to use mortar made of cement and yellow sand for plastering and leveling, and then apply ordinary putty. The disadvantage is that the putty material and the wall are not directly bonded, but A layer of mortar material is sandwiched, because the mortar material is easy to spill, pollute the environment, and waste materials; and the mortar layer is prone to cracking, hollowing, and labor-intensive materials; in addition, ordinary putty has low strength, relatively small adhesion, and is easy to crack. In humid environment, it is easy to fall off. Contents of the invention [0004] The purpose of the present invention is to provide a construction method for applying a special putty-based mixture on the a...
