Description
Technical field
The invention belongs to premixing dry powder and mortar field, and in particular to a kind of modified form can machine and spray pump send mortar.
Background technology
Dry-mixed mortar is also known as dry powder and mortar, dry-mixed mortar or premix(It is dry)Mortar, refers to have production by professional production,
Fine aggregate through drying screening process is mixed by a usual practice with inorganic binder, water-keeping thickening material, mineral admixture and additive
A kind of graininess or pulverulent mixture closed;In construction, the construction of pure smearing by hand has drawback, labour intensity
Greatly, working time is long, labour is in short supply, causes the defect of low production efficiency, so as to influence some construction nodes in engineering construction
Progress;Simultaneously because of the restriction of scene production conditions, it is impossible to meet requirement of the product for different raw material, influence the property of mortar
Energy;It is substantial amounts of building wall and the stage of plastering, rare because of professional bricklayer after such as project subject binds, directly affects work
Cheng Jindu, also brings building trade common fault, including wall crazing, infiltration and coat of plaster hollowing, the phenomenon such as come off happen occasionally.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of modified form can machine and spray pump send sand
Slurry;Using the modified form can machine and spray pump send mortar, spraying application is pumped by mechanization can change and manually build by laying bricks or stones and smear at present
The construction status of ash, comply with the particular/special requirement of mechanized construction, and the completion construction of fast and high quality also complies with China's propulsion building
It is energy-saving, " prohibiting existing " policy of greenization building materials.
It is a further object of the present invention to provide above-mentioned modified form can machine and spray pump send the preparation method of mortar.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that:
A kind of modified form can machine and spray pump send mortar, be made from the following raw materials in parts by weight:150~200 parts of cement, flyash 50~
