Abstract
The invention discloses a kind of light cement base mortar and preparation method thereof, which formed by cement, flyash, ground granulated blast furnace slag or fine sand, bubble slag, boiler bottom slag, hydroxypropyl methyl cellulose, polyvinyl alcohol by weight.Light weight cement mortar of the present invention has the characteristics that big light, good water-retaining property, bonding force, anti-hollowing, cracking resistance seam, is the substitution of traditional cement mortar.It not only efficiently solves because cement mortar poor water retention property, dry after-contraction are big, causes wall plastering hollowing, crack construction quality common fault, while making solid waste is comprehensive to recycle, protect environment, saved resource.
Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of light cement base mortar and preparation method thereof.
Background technique
Light cement base mortar is a kind of new green environment protection type construction material of alternative traditional cement mortar, build,
Plastering not only has the characteristics such as light, bonding force is strong, heat preservation, heat-insulated, fire resisting, but also efficiently solves conventional cement sand
The problems such as slurry poor water retention property, drying shrinkage are big, wall plastering hollowing, crack.Thin layer can be achieved to build and plaster, unit builds square meter sand
It is few to starch dosage, reduces construction cost.
Flyash is the fine ash that catching is got off from the flue gas after coal combustion, and flyash is the main solid of coal-burning power plant's discharge
Body waste；Ground granulated blast furnace slag is the fine powder smelted iron after slag mill；Bubble slag be ironmaking when be added suitable flux (lime etc.) into
Row adjustment heel row is removed, the melting waste slag formed with water rapid cooling；Boiler bottom slag is exactly the coal dusts such as power plant or steam power plant
The waste residue excluded after furnace or fluid bed furnace coal combustion from boiler bottom has blocky, graininess and powdery.These solid wastes are not
It is used effectively, waste is big, pollutes environment.Flyash, bubble slag, boiler bottom slag etc. are carried out waste utilization, system by the present invention
At light cement base mortar, resource has not only been saved, but also has effectively played light cement base mortar lightweight, anti-hollowing, cracking resistance
Seam, it is environmentally protective the advantages that.
Summary of the invention
Present invention aims at, a kind of light cement base mortar and preparation method thereof is provided, the mortar be by weight by
Cement, flyash, ground granulated blast furnace slag or fine sand, bubble slag, boiler bottom slag, hydroxypropyl methyl cellulose, polyvinyl alcohol and
At.Light weight cement mortar of the present invention has the characteristics that big light, good water-retaining property, bonding force, anti-hollowing, cracking resistance seam, is
The substitution of traditional cement mortar.It not only efficiently solves because cement mortar poor water retention property, dry after-contraction are big, causes wall
Gaul, crack construction quality common fault, while making solid waste is comprehensive to recycle, environment is protected, resource has been saved.
A kind of light weight cement mortar of the present invention, the mortar are by cement 13-20%, flyash 5.3- by weight
15%, ground granulated blast furnace slag or fine sand 5-20%, bubble slag 60-31.5%, boiler bottom slag 9.6-20.32%, hydroxypropyl methyl cellulose
0.05-0.08, polyvinyl alcohol 0.05-0.1 are mixed.
A kind of preparation method of light weight cement mortar follows these steps to carry out:
A, it by the bottom ash or clinker of boiler or coal-powder boiler or fluid bed furnace, is crushed, through≤3mm sieve screening, it is spare；
B, iron-smelter bubble slag is crushed, through≤2.5mm sieve screening, it is spare；
C, by weight respectively by cement 13-20%, flyash 5.3-15%, ground granulated blast furnace slag or fine sand 5-20%, bubble slag 60-
31.5%, blender is added in boiler bottom slag 9.6-20.32%, hydroxypropyl methyl cellulose 0.05-0.08, polyvinyl alcohol 0.05-0.1
3-5 minutes are mixed to get light weight cement mortar.
D, obtained light weight cement mortar is packed and stored as finished product.
A kind of light cement base mortar of the present invention and preparation method thereof, it has the advantage that:
The light weight cement mortar is by cement, flyash, blast furnace iron powder or fine sand, bubble slag, boiler bottom slag, hydroxypropyl first
Novel green construction material made of base cellulose and polyvinyl alcohol.The light weight cement mortar have light, good water-retaining property,
The features such as bonding force is big, heat preservation, heat-insulated, fire resisting, anti-hollowing, cracking resistance are stitched, not only efficiently solve because cement mortar poor water retention property,
Dry after-contraction is big, causes wall plastering hollowing, crack construction quality common fault, realizes thin-coat plaster technology, make plastering construction cost
It reduces, while making solid waste is comprehensive to recycle, protect environment, saved resource, economic benefit and social benefit are obvious.Have
Effect solves the Utilizing question for the solid waste that prior art limitation is not able to achieve.
Light cement base mortar of the present invention preparation is simple, and materials are convenient, and production cost is low, have bulk density is small, workability is good,
The features such as unit construction area dosage is few, and construction cost is low, has a vast market foreground.
