Abstract
The invention discloses a kind of plastering mortars, by weight, including following component: 50-80 parts of cement, 30-50 parts of flyash, 60-90 parts of sand material, 10-15 parts of black talc powder, 8-12 parts of formic acid calcium powder, 5-8 parts of water-reducing agent, 2-5 parts of hydroxypropyl methyl cellulose ether, 1-2 parts of air entraining agent, 2-4 parts of wood fibre, plastering mortar of the invention have sag resistance, preferable lubricity, water-retaining property, mobility, stronger cohesive force reaches the performance requirement of the pumping of plastering mortar machinery, spraying application；It reduces labor intensity, improve construction efficiency, work efficiency improves two times or more compared with artificial plastering；Wall plastering is constructed using mechanically spraying, and pressure is big and uniformly avoids hollowing, the crack of coat of plaster, improves construction quality.
Description
Technical field
The present invention relates to the field of building materials, especially a kind of plastering mortar.
Background technique
Mainly have two kinds building the plastering mortar used at present: one is building-sites from the plastering mortar mixed, and measures
Low precision, unstable quality be easy to cause the quality accidents such as hollowing, crack；Another kind is that national policy encourages the industry supported
The premixing mortar that metaplasia produces, metering is accurate, quality is stablized, and also has many advantages, such as the useless environmental protection of benefit；But there are also one for above two kinds of mortars
A common drawback: it is low using artificial plastering large labor intensity, construction efficiency, also make wall quality hidden danger caused by working medium amount.
It is very urgent that plastering mortar in view of disadvantages described above develops a kind of pumping of satisfaction, the mortar of mechanically spraying performance.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of plastering mortar.
The technical solution adopted in the present invention is mainly: a kind of plastering mortar, by weight, including following component: cement
50-80 parts, 30-50 parts of flyash, 60-90 parts of sand material, 10-15 parts of black talc powder, 8-12 parts of formic acid calcium powder, 5-8 parts of water-reducing agent,
2-5 parts of hydroxypropyl methyl cellulose ether, 1-2 parts of air entraining agent, 2-4 parts of wood fibre.
As an improvement of the above technical solution, the cement is 32.5 grades of ordinary portland cements.
As a further improvement of the above technical scheme, the sand material is the quartz sand of 50-70 mesh granularity, and water content is small
In 3%.
Further, the flyash is levigate II grades of ash.
Further, the water-reducing agent is naphthalene series high-efficiency water-reducing agent.
The beneficial effects of the present invention are:
A kind of plastering mortar of the invention, with sag resistance, preferable lubricity, water-retaining property, mobility, stronger bonding
Power reaches the performance requirement of the pumping of plastering mortar machinery, spraying application；It reduces labor intensity, improve construction efficiency, with people
Work plastering improves two times or more compared to work efficiency；Wall plastering is constructed using mechanically spraying, and pressure is big and uniformly avoids coat of plaster
Hollowing, crack, improve construction quality.
Specific embodiment
The present invention will be further described in detail with reference to the specific embodiments.

Embodiment 3: a kind of plastering mortar of the invention, by weight, including following component: 80 parts of cement, flyash 50
Part, 90 parts of sand material, 15 parts of black talc powder, 12 parts of formic acid calcium powder, 8 parts of water-reducing agent, 5 parts of hydroxypropyl methyl cellulose ether, air entraining agent 2
Part, 4 parts of wood fibre, wherein cement is preferably 32.5 grades of ordinary portland cements, and sand material is preferably the quartz of 70 mesh granularities
Sand, water content is less than 3%, and flyash is preferably levigate II grades of ash, and water-reducing agent is preferably naphthalene series high-efficiency water-reducing agent.
Plastering mortar of the invention have sag resistance, preferable lubricity, water-retaining property, mobility, stronger cohesive force,
Reach the performance requirement of the pumping of plastering mortar machinery, spraying application；It reduces labor intensity, improve construction efficiency, and it is artificial
Plastering improves two times or more compared to work efficiency；Wall plastering is constructed using mechanically spraying, and pressure is big and uniformly avoids coat of plaster
Hollowing, crack, improve construction quality.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, as long as with essentially identical
Means realize that the technical solution of the object of the invention belongs within protection scope of the present invention.
