Problems solved by technology

[0002] In current construction projects, after the dry-hanging process of pasting tiles and panels indoors and outdoors, it is the process of filling cement mortar. -5, limestone sand 60-75, additive 0.24-0.40; specific gravity is about 1700-1800Kg / m3, thermal conductivity is 0.93W / (m·K 25℃)) has a large self-weight, and the gravity is transmitted to the back, after adding water and stirring The flow performance is poor, it is difficult to fill the various parts behind the panel, and the one-time accumulation is too high, which increases the external thrust of the bottom, causing the tile or panel to tilt, resulting in deviation, and it is difficult to be dense and uniform, and the adhesive performance is poor, and there are voids in more than 50% drum phenomenon
Secondly, due to the heavy weight of the existing mortar, there are many consumables, the burden of vertical transportation is heavy, the thermal conductivity is high, there is no energy-saving effect, and the workability is poor.

Embodiment 1

[0036] Take each component according to the weight shown in Example 1 in Table 1, and the production process is as follows: ordinary Portland cement, aluminate cement with a model of CA-50, gypsum, light aggregate, heavy aggregate, and D-type compound The additives are mixed according to the above specific gravity, stirred evenly by mechanical means, packed in paper bags or packed in bulk, and the lightweight superfluidity filled mortar of this embodiment can be obtained.

[0037] Dilute the light super-fluidity filling mortar obtained above with 100 kg of mortar and 30 kg of water, stir it mechanically or manually until it is evenly mixed, and reach a viscosity suitable for mechanical spraying or manual construction, then carry out mechanized spraying or manual work.

[0038] The performance test results are shown in the corresponding data of Example 1 in Table 2, wherein the test basis for dry surface density is GB / T 20473-2006, the test basis for thermal conductivity is GB / T...

Embodiment 2

[0040] Get each component with the weight shown in Example 2 in Table 1, repeat the production process described in Example 1 (only each component weight changes) to obtain the lightweight superfluidity filled mortar of Example 2; Repeat in Example 1 The construction method is to dilute 100 kg of mortar with 40 kg of water, stir mechanically or manually until it is evenly mixed, and then carry out mechanized spraying or manual work. The performance test was performed based on the basis described in Example 1, and the results are shown in the corresponding data of Example 2 in Table 2.

Embodiment 3

[0042] Get each component with the weight shown in Example 3 in Table 1, repeat the production process described in Example 1 (only each component weight changes) to obtain the lightweight superfluidity filled mortar of Example 3; Repeat in Example 1 The construction method is to dilute 100 kg of mortar with 50 kg of water, stir mechanically or manually until the mixture is uniform, and then carry out mechanized spraying or manual work. The performance test was performed based on the basis described in Example 1, and the results are shown in the corresponding data of Example 3 in Table 2.

Abstract

A light super-fluidity padding mortar used indoor and outdoor is formed by mixing 28 to 32 parts by weightof R325 type or better ordinary Portland cement, 5 to 10 parts by weightof CA-50 type aluminate cement, 4 to 5 parts by weightof gypsum having a fineness more than 75 meshes, 8 to 12 parts by weightof light aggregate, 40 to 50 parts by weightof heavy aggregate (river sand), and 1.0 part by weight of compound auxiliary agent, wherein the light aggregate is an inorganic vitrified hollow pore material which has a fineness less than 100 meshes, and the compound auxiliary agent is formed by mixing 0.5 part by weightof air entraining agent, 0.3 part by weightof cellulose ether, 0.1 part by weightof re-scattering latex powder and 0.1 part by weightof water reducer. The padding mortar is diluted by adding 30 to 50 percent by weight of water and then the mixture is mixed uniformly by mechanically or manually stirring so as to reach a viscosity fit for mechanically coating or manually constructing in order to coat mechanically or construct manually. The mortar uses the specific light aggregate so the mortar has the advantages of light weight, good fluidity, excellent pasting property, difficulty to form empty drum, low heat conducting factor, energy saving, low manufacturing cost for unit area, wide indoor and outdoor application and great popularizing value.
