Abstract
A kind of high level pneumatic conveying mortar, including aggregate, inorganic coagulation material and additive through dry screening process, the aggregate uses Machine-made Sand, and 0.075mm powder containing quantity below is more than or equal to 28% in the aggregate, and 1.2mm or more partial size is less than or equal to 25%.The present invention provides a kind of Machine-blasting mortar of pneumatic conveying for being able to achieve high-rise conveying, stability is higher.
Description
Technical field
The invention belongs to dry-mixed mortar fields, and in particular to a kind of Machine-blasting mortar for being able to achieve high-rise pneumatic conveying.
Background technique
Dry-mixed mortar refers to will select standby fine work aggregate, quantitative cementitious material (such as cement) and various high-performance as required
The pulverulent mixture that trace mineral supplement mixes according to a certain percentage, and in bulk in the form of dry mash or packaging finished sand
Slurry.In use, need to only water be added to mix and stir, and quality assurance.
Existing dry-mixed plastering mortar is mostly mortar silo lower section stirring at the scene or dismounts with packaging in construction floor
Construction surface is transported to by cart after the stirring of lower section, dust raising phenomenon is serious in whipping process and waste of material is more, while material exists
The transportational process such as time too long will affect its mortar quality after the completion of stirring.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of machine sandblasting of pneumatic conveying for being able to achieve high-rise conveying
Slurry, stability are higher.
A kind of high level pneumatic conveying mortar, including aggregate, inorganic coagulation material and additive through dry screening process, institute
It states aggregate and uses Machine-made Sand, 0.075mm powder containing quantity below is more than or equal to 28% in the aggregate, and 1.2mm or more partial size is less than
Equal to 25%.
Further, using Machine-made Sand total amount as radix 1, the Machine-made Sand grade screening aperture and ratio are as follows: 2.4mm,
(2 ± 2) %；1.2mm, (18 ± 3) %；0.6mm, (15 ± 3) %；0.3mm, (15 ± 3) %；0.15mm, (10 ± 3) %；
0.075mm, (10 ± 3) %；Chassis, (30 ± 2) %.
Further, 0.075mm powder containing quantity 28%-32% below in the aggregate, 1.2mm or more partial size 20%-
25%.
Further, the additive is not more than 3 kinds.
Further, the additive is cellulose ether, thixotropic lubricant and water-reducing agent.
Further, the aggregate further includes the glass fibre of 1%-2%.
Further, the fiberglass size is less than 3mm.
Compared with prior art, the invention has the following advantages:
1. this dry-mixed mortar gradation has preferable Modulatory character, and can guarantee it compared to the uncontrollability of common river sand
Stablize.Mortar can be delivered directly to floor construction surface from construction site silo by pneumatic transport equipment and stirred by this dry-mixed mortar
It mixes, with mixing with can transport to 150 meters or more of floor use to reduce the wasting phenomenon of material during transportation.
The haulage time for eliminating mortar simultaneously makes mortar that can use the matter that ensure that mortar in construction surface at the first time after discharging
Amount.
2. additive control of the invention is within 3, practice is obtained, additive level is bigger, product workability
It is more unstable with other performances, in the market other mostly dominate modified product ratio by additive, the present invention in aggregate proportion and
It is adjusted in structure, so that stability is higher, is more suitable pneumatic transportation and machine spray is used.
3. part glass is added in this product, it can preferably realize that ball-type continuously sprays during machine sprays.
Specific embodiment
The present embodiment uses the conveyance conduit of mortar for 50mm, discharge pressure be 1.8 megapascal, guarantee mortar can strength
Transporting is the main technical point of mortar, by multiple pneumatic conveying experiments have shown that realize in pneumatic conveying mortar first
0.075mm powder containing quantity below can not be less than 28%, as being less than in 28% transmission process containing component for 0.075mm will appear plugging
Phenomenon, 1.2mm or more partial size can not be greater than 25% in mortar, such as larger than 25% mortar be delivered to construction surface can generate it is serious from
Analyse phenomenon.Wherein 0.075mm powder containing quantity 28%-32% below, 1.2mm or more partial size 20%-25% is best.
It is as follows that powder containing quantity influences part test data to pneumatic conveying:
According to above-listed list data can be seen that the powder containing quantity in mortar pneumatic conveying and mortar material be it is closely related,
Powder containing quantity is lower than easy line clogging in 28% transmission process and material heels in pipeline is more.
Influence for 1.2mm or more partial size Machine-made Sand to pneumatic conveying mortar goes out basis in experiment laboratory test first
Data are transported according to basic data, convey actual measurement, analyzed using actual shipment case, for pneumatic conveying occurs
The component ratio variation with dry-mixed mortar in the transport storehouse after pneumatic conveying is further analyzed before, part test data
It is as follows:
Actual measurement experiment carries out height increase test after measuring optimum data range on the basis of 25 floor high conveying heights.
Measured data is excessive, and only disclosure portion fractional data in the present embodiment can be seen that mortar pneumatic conveying according to above-listed list data
Be with the coarse granule (1.2mm or more particle) in mortar material it is closely related, content be higher than 24% when be transported to floor construction
Face easily causes serious isolation.Meanwhile for the component of middle particle, the Machine-made Sand component of 0.6mm-0.15mm partial size is
One relatively uniform component is stablized from coarse granule to fine grain gradation relationship.
It is ideal it is dry-mixed can pneumatic conveying mortar gradation it is as follows, can reach under conditions of pneumatic transport equipment allows
At least 35 layers or more of conveying:
One embodiment of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.
