Description
Technical field
The invention belongs to building material fields, and in particular to a kind of mechanical injection wet-mixing plastering mortar and preparation method thereof.
Background technology
Ecological Civilization Construction is one of the important content of " 13 " planning, and it is the base of China to economize on resources with environmental protection
This state basic policy.It develops a circular economy, preserves the ecological environment, the theory built a resource-conserving and environment-friendly society has become society
It can know together extensively.With the promotion of construction modernization level, China starts to carry out green building, and puts into effect《Green building
Evaluation criterion》, it has been related specifically to energy-saving and emission-reduction.And wet mixing mortar has wide city as novel green construction material
Field foreground, then pass through mechanically spraying, it is contemplated that the application of injection wet-mixing plastering mortar will bring the significant innovation of field of mortar.
Wet-mixing plastering mortar sprayed using flush coater, instead of the full handwork of traditional mortar, realizes the commercialization and construction of mortar
Mechanization is conducive to improve civilized construction, reduces dust airborne dust, improve construction quality, accelerate speed of application, thus to promote hair
Exhibition circular economy and realization energy-saving and emission-reduction provide safeguard.
Mechanical injection wet-mixing plastering mortar is the synthesis of wet mixing mortar and mechanized operation.Currently, wet mixing mortar is most
It is produced, only need to be simply transformed in original mixing plant Equipment Foundations, raw material is not necessarily in the mixing plant of production concrete
Drying, matches accurate, stable quality, and centralized production not will produce secondary pollution.It is used flush coater to spray, is replaced traditional
Handwork and the missing for making up plasterer ensure construction quality under the premise of lifting construction speed.For presently, there are
Scene from sand cutting starch, the easy bleeding of mortar, performance-sensitive causes construction quality to be more difficult to get guarantee, in addition, in production process
In can cause a large amount of airborne dusts and noise pollution.Therefore, mechanical injection wet-mixing plastering mortar has both economic benefit and environmental benefit, is
The green construction material of novel practical.
The associated documents for forbidding Site mortar were assigned in China in 2007, and " prohibiting existing " is gradually carried out in each department, to sand
The research in slurry field is more and more deep, some economically well-developed provinces are more mature in the application of field of mortar.But cut-off mesh
Before, the key technology of mechanical injection wet-mixing plastering mortar and application study do not draw attention also in China, not yet form production so far
Industry.Once mechanical injection wet-mixing plastering mortar obtains practical application, it can not only drive the development of related Manufacturing, and expand according to this
Exhibition extend to form a complete industrial chain so that China's mortar industry development integrates with advanced international standard, constantly reduce with
The gap of developed country, and recruitment famine problem existing for current building trade can also be alleviated, ensure the sustainable development of construction industry
Exhibition.This not only conforms with the development trend of national green construction material and product mechanized operation, also complies with China in " 13 "
The requirement of Ecological Civilization Construction in planning.Therefore, for there are civilized construction degree low, long construction period and the plastering of current industry
The present situations such as worker's deficiency design and develop out a kind of mechanical injection wet-mixing plastering mortar.
Invention content
The present invention be directed to the deficiencies in the prior art, and it is an object of the present invention to provide a kind of mechanical injection wet-mixing plastering mortar and
Preparation method, can solving scene, there are dust airborne dust, noise pollution, plasterer are short from sand cutting slurry and dry-mixed mortar
Lack, long construction period the defects of.
For achieving the above object, the technical solution adopted in the present invention is：
A kind of mechanical injection wet-mixing plastering mortar is mixed by cement, flyash, sand, additive and water, each component
It is calculated by weight as：180~240 parts of cement, 140~180 parts of flyash, 1200~1300 parts of sand, 4~6.6 parts of additive,
240~300 parts of water.
In said program, the additive includes water-reducing agent, retarder and thickener, the water-reducing agent, retarder and increasing
Thick dose of mass ratio is 30~60：5~20：1~5.
In said program, the water-reducing agent is polycarboxylic acids dehydragent, and solid content is 8 ± 2%, and chloride ion content is little
In 0.1%.
In said program, the retarder is one or more of phosphate, calcium lignosulfonate, sodium gluconate and white sugar.
In said program, the thickener is hydroxypropyl methyl cellulose ether and/or xanthans.
In said program, the sand is sand in the screenings after 4.75 millimeters of sieve pores are sieved, the fineness modulus of the sand
It is 2.3~2.7.
In said program, the water is tap water or drinking water, is met《Concrete water standard》The requirement of JGJ63.
In said program, the cement is Portland cement, is met《Common portland cement》GB175-2007's
It is required that.
In said program, the flyash is II grade of flyash, is met《For the flyash in cement and concrete》GB/
The requirement of T1596-2005.
Beneficial effects of the present invention：Mechanical injection wet-mixing plastering mortar of the present invention, consistency is suitable, water-retaining property is strong,
Open hour are controllable, stable quality, on the basis of ensureing and improving construction engineering quality, can effectively improve construction efficiency,
Shorten construction period, improve construction organization；Mechanical injection wet-mixing plastering mortar of the present invention is a kind of environmentally protective production
Product may replace the handwork of traditional mortar, make up the deficiency of plasterer, be conducive to raising civilized construction, reduction dust is raised
