Embodiment 1

[0023] A mechanical jetting wet-mixing plastering mortar, the mass parts of each component of the mortar are as follows: 180 parts of cement, 180 parts of fly ash, 1200 parts of sand, 240 parts of water, and 6.6 parts of admixture.

[0024] The admixture includes raw materials in the following mass ratio, and the mass ratio of water reducer: retarder: thickener is 60:5:1.

[0025] After the above-mentioned cement, fly ash, sand, water, and additives are weighed according to the mass fraction, the mortar described in the present invention can be obtained after being stirred by a mortar mixer for 2 minutes. The mortar has strong cohesiveness, suitable consistency, and relatively high viscosity Large, good water retention, controllable opening time, no bleeding. The results of the mortar performance test are shown in Table 1.

Embodiment 2

[0027] A mechanical jetting wet-mixing plastering mortar, the mass parts of each component of the mortar are as follows: 220 parts of cement, 140 parts of fly ash, 1200 parts of sand, 250 parts of water, and 6.3 parts of admixture.

[0028] The admixture includes raw materials in the following mass ratio, and the mass ratio of water reducer: retarder: thickener is 45:15:3.

[0029] After the above-mentioned cement, fly ash, sand, water, and additives are weighed according to the mass fraction, the mortar described in the present invention can be obtained after being stirred by a mortar mixer for 2 minutes. The mortar has strong cohesiveness, suitable consistency, and relatively high viscosity Large, good water retention, controllable opening time, no bleeding. The results of the mortar performance test are shown in Table 1.

Embodiment 3

[0031] A mechanical jetting wet-mix plastering mortar, the mass parts of each component of the mortar are as follows: 220kg of cement, 160kg of fly ash, 1250kg of sand, 270kg of water, and 5.3 parts of admixture.

[0032] The admixture includes raw materials in the following mass ratio, and the mass ratio of water reducer: retarder: thickener is 40:10:3.

[0033] After the above-mentioned cement, fly ash, sand, water, and additives are weighed according to the mass fraction, the mortar described in the present invention can be obtained after being stirred by a mortar mixer for 2 minutes. The mortar has strong cohesiveness, suitable consistency, and relatively high viscosity Large, good water retention, controllable opening time, no bleeding. The results of the mortar performance test are shown in Table 1.

Abstract

The invention belongs to the field of building materials, and particularly relates to mechanical injection wet-mixing plastering mortar and a preparing method thereof. The mechanical injection wet-mixing plastering mortar is prepared from, by weight, 180-240 parts of cement, 140-180 parts of flyash, 1200-1300 parts of sand, 4-6.6 parts of additives and 240-300 parts of water. The additives include a water reducing agent, retarder and a thickening agent by the mass ratio of (30-60):(5-20):(1-5). The mechanical injection wet-mixing plastering mortar is suitable in consistence, high in water-retaining property and stable in quality, and the opening time is controllable; on the basis of ensuring and improving building engineering quality, the construction efficiency can be effectively improved, the construction period can be effectively shortened, and construction organization can be effectively improved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a mechanically sprayed wet-mixed plastering mortar and a preparation method thereof. Background technique [0002] The construction of ecological civilization is one of the important contents of the "13th Five-Year Plan", and saving resources and protecting the environment are China's basic national policies. The concept of developing circular economy, protecting the ecological environment, and building a resource-saving and environment-friendly society has become a broad consensus in the society. With the improvement of the modernization level of building construction, my country has begun to promote green buildings, and issued the "Evaluation Standards for Green Buildings", especially involving energy conservation and emission reduction. As a new type of green building material, wet-mix mortar has broad market prospects, and through mechanical spraying, it can be ...
