Abstract
The invention discloses a mechanically sprayed plastering mortar. The mechanically sprayed plastering mortar comprises, by weight, 25% of P.O42.5 general portland cement, 10% of secondary fly ash, 20% of dry machine-made medium sands, 44.2% of dry natural medium sands, 0.5% of re-dispersible latex powder, 0.2% of starch ether and 0.1% of lignocellulose. The mechanically sprayed plastering mortar produced through after reasonably optimizing the proportions of above components has the advantages of strong adhesion stress between a plastered layer and a substrate, effective solving of the hollowing, cracking and peeling problems of walls, realization of reliable quality, fastness and convenience in plastering construction, obvious shortening of the construction period, work efficiency increase, labor intensity reduction, labor cost reduction, and improvement of the construction working environment.
Description
Technical field
The present invention relates to building material technical field, particularly to a kind of mechanically spraying motar.
Background technology
Mechanically spraying motar is applicable to architectural engineering wall cylindrical surface, ceiling, roofing, flooring and general
The mechanically spraying plastering construction on structures surface, but the denseness of existing mortar and water retention are difficult to control to rationally
In the range of, and aggregate size scope and modulus of fineness unreasonable, thus cause comprcssive strength and the bonding of mortar
Intensity can not meet corresponding performance requirement.
Summary of the invention
The problem low for solving existing machinery spray plaster consistency of mortar, water retention and comprcssive strength, the present invention
Disclosing a kind of mechanically spraying motar, the component of this mechanically spraying motar and percentage by weight be:
P.O42.5 common portland cement 25%, second class powered coal ash 10%, it is dried mechanism medium sand 20%, is dried natural
Medium sand 44.2%, redispersable latex powder 0.5%, starch ether 0.2%, lignocellulose 0.1%.
As a further improvement on the present invention, described redispersable latex powder is ethylene, being total to of vinylacetate
Polymers, makees protecting colloid with polyvinyl alcohol.
As a further improvement on the present invention, the composition of described second class powered coal ash be silicon dioxide, aluminium oxide with
And ferric oxide.
As a further improvement on the present invention, the production temperature of described mechanically spraying motar is for being less than
60 DEG C, temperature is used to be 5-35 DEG C.
The invention has the beneficial effects as follows:
The proportioning of the various component of reasonably optimizing of the present invention, uses this mechanically spraying motar, coat of plaster and base
Layer cohesive force is strong, it is possible to effectively solves wall hollow drum, ftracture and the problem such as decortication, plastering construction reliable in quality,
Efficient and convenient, can substantially the reduction of erection time, improve work efficiency, reduce and reduce recruitment while labor intensity and become
This, and construction operation environment can be improved.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that retouched
The embodiment stated is only a part of embodiment of the present invention rather than whole embodiments.
A kind of mechanically spraying motar, the component of this mechanically spraying motar and percentage by weight be:
P.O42.5 common portland cement 25%, second class powered coal ash 10%, it is dried mechanism medium sand 20%, is dried natural
Medium sand 44.2%, redispersable latex powder 0.5%, starch ether 0.2%, lignocellulose 0.1%.
Wherein, redispersable latex powder is the copolymer of ethylene, vinylacetate, protects with polyvinyl alcohol
Colloid；The composition of second class powered coal ash is silicon dioxide, aluminium oxide and ferric oxide；This mechanically spraying is plastered
The production temperature of mortar is less than 60 DEG C, uses temperature to be 5-35 DEG C.
The product performance index of the present invention is as follows:
Above-mentioned each achievement data and construction reference perform with reference to following national standard or industry standard:
JC890-2001: " steam-pressing aero-concrete masonry mortar and decorative mortar "
JG/T230-2007: " premixing mortar "
GB/T25181-2010: " premixing mortar "
JGJ/T220-2010: " motar technical regulation "
JGJ/T105-2011: " mechanically spraying plastering construction code "
JG/T291-2011: " dry-mixed mortar of building by laying bricks or stones and plaster for building "
The proportioning of the various component of reasonably optimizing of the present invention, uses this mechanically spraying motar, coat of plaster and base
Layer cohesive force is strong, it is possible to effectively solves wall hollow drum, ftracture and the problem such as decortication, plastering construction reliable in quality,
Efficient and convenient, can substantially the reduction of erection time, improve work efficiency, reduce and reduce recruitment while labor intensity and become
This, and construction operation environment can be improved.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
