Embodiment 1-6

[0026] As shown in Table 1, weigh and mix the raw materials according to the mass percentage, add 22-25% of water and stir to form a uniform non-agglomerated thick mixture.

[0027] Table 1

[0028]

Embodiment 1

[0029] In Example 1, a relatively large amount of dry sand and thermal insulation filler are used, and its thermal conductivity is the lowest under the guarantee of compressive strength and bond strength; in actual mechanical construction, compared with other examples, its pumping performance is slightly worse.

Embodiment 2

[0030] Embodiment 2 On the basis of Embodiment 1, the consumption of fly ash and redispersible latex powder is gradually increased, and the consumption of vitrified microspheres is reduced. The compressive strength and tensile bond strength increase, but the thermal conductivity also increases. significantly increased.

Abstract

The invention relates to masonry mortar for autoclaved aerated concrete. The masonry mortar is prepared from the following components in percentage by mass: 25%-30% of cement, 30%-50% of dry sand, 10%-30% of heavy calcium carbonate, 0-10% of fly ash, 0-2% of thermal-insulating filler and 0.2%-2% of an additive. According to the masonry mortar, on the premise that identical performance of the masonry mortar for the autoclaved aerated concrete is guaranteed, the mechanical construction performance of the masonry mortar is improved, the problem of difficulty in construction mortar application to aerated concrete block masonry is solved, mortar on the masonry surface is applied uniformly, the masonry quality is guaranteed, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a masonry mortar for autoclaved aerated concrete. Background technique [0002] The popularization and application of autoclaved aerated concrete blocks as a new wall material reduces the load-bearing quality of building structures, and its thermal insulation properties improve the energy-saving effect of buildings. The large-volume specification design, which is different from traditional bricks, improves the progress of production, transportation and construction. However, in actual masonry construction, due to the large size of a single block, manual sizing is difficult, and it is easy to cause uneven smearing, which affects construction. quality. [0003] Based on this, the present invention is proposed. Contents of the invention [0004] In view of the above-mentioned technical problems of the prior art, the object of the present invention is to pr...
