Embodiment 1

[0034] Building energy-saving lightweight thermal insulation and anti-cracking cement, the components are as follows in parts by weight:

[0035]

[0036] Manual scraping or mechanical spraying can be used. The average construction thickness is 5-8mm.

Embodiment 2

[0038] Building energy-saving lightweight thermal insulation and anti-cracking cement, the components are as follows in parts by weight:

[0039]

[0040] For construction methods and requirements, refer to Embodiment 1.

Embodiment 3

[0042] Building energy-saving lightweight thermal insulation and anti-cracking cement, the components are as follows in parts by weight:

[0043]

[0044] For construction methods and requirements, refer to Embodiment 1.

[0045] The construction method of the present invention can be manually scraped or mechanically sprayed. Ordinary mortar can only be constructed manually by layered scraping; When the next layer of construction is carried out, it is necessary to wait for the mortar of this layer to reach a certain degree of dryness; the use of mechanical spraying can also save labor and shorten the construction period; the average construction thickness is 5-8mm, and the traditional construction thickness is 15-20mm. It is equivalent to increasing the usable area of ​​the house. Every meter of wall increases the plane usable area by about 0.010-0.015㎡; the dry powder density is 800-1000kg / m 3 , the traditional dry-mixed mortar and wet-mixed mortar are all converted into ...

Abstract

The invention discloses cement paste for buildings with energy conservation, lightweight, insulation and crack resistance. The cement paste comprises the following components: cement, fine sand whose particle size is less than or equal to 0.38mm, stone flour whose particle size is less than or equal to 0.15mm, vitreous beads whose particle sizes are in the range of 0.15 to 0.30mm, HPMC, a thixotropic lubricant, dispersible latex powder, and anti-crack fiber. The cement paste is advantageous in that a scrape coating by manual operation or scrape coating by machine can be used as a construction mode, construction cycle is short, thin layer construction reduces bearing of walls, and bonding strength is high; the cement paste has the effects of wear resistance, corrosion resistance, fire prevention, energy saving and heat insulation, and cracking resistance; the cement paste is not easy to be damaged by worms, and harmful gas is not released.

Description

technical field [0001] The invention relates to the field of building materials, in particular to the field of lightweight, crack-resistant high-performance cement materials. Background technique [0002] With the development of the residential market, people have higher and higher requirements for living comfort, so the requirements for the performance of new energy-saving materials for interior walls are getting higher and higher. In addition to high strength, wear resistance, corrosion resistance, fire prevention, insect resistance, In addition to notable features such as no harmful gas release, it also requires thin-layer construction to increase the usable area, light weight to reduce the weight of the wall, have certain thermal insulation performance, good crack resistance, save labor costs, and shorten the construction period. At present, neither cement and sand scraping with traditional on-site mixing, nor wet-mixed mortar, dry powder ordinary plastering mortar can m...
