Description
Technical field
The invention belongs to green construction material technical fields, are related to a kind of side configuring cement and its configuration using flyash
Method.
Background technology
Flyash is the substance of coal-burning power plant's discharge collected through precipitator.Fine coal in the lime-ash that fire coal is formed
Ash accounts for about 4/5, and bottom ash accounts for about 1/5.Different according to coal source and type, there were significant differences for the flyash of formation.China is with coal
Generated by coal for the country of main energy sources, the 76% of electric power, fire coal generate the total volume of cargo in storage of flyash more than 1,000,000,000 t, and
And also become maximum ash discharge state in the world in the speed increase with annual 0.8 hundred million~100,000,000 t.Flyash storage does not only take up big
Soil is measured, serious environmental pollution can be also caused.Carry out the comprehensive utilization of the coal solid wastes such as flyash, extends Coal Industrial
Chain is not only related to Chinese coal industry, power industry and related industries sustainable development, but also to protection soil money
Source reduces, eliminates pollution, realizes that circular economy is of great significance.
Main production Portland fly ash cement domestic at present and coal ash clinker-free cement two types.According to flyash
Volume be divided into two kinds of different situations：(1) production Portland cement and portland slag cement, doping quantity of fly ash≤
15%；(2) pulverized fuel ash cement is produced：Mixing material is done with flyash, volume size is 20%~40%.
Invention content
The object of the present invention is to provide a kind of methods configuring cement and its configuration using flyash.The present invention with
Flyash has activity well for the cement of primary raw material configuration, with barrier properties are good, flexible, non-deformability is strong, anti-
The advantages that jelly ability is strong, easy for installation, comprehensive cost low.
For this purpose, the present invention adopts the following technical scheme that：
2, a kind of method configuring cement and its configuration using flyash, mixes according to the raw material of following ratio：
60-75 parts of flyash；
20-25 parts of mountain flour；
15-30 parts of quartz sand；
8-12 parts of water-reducing agent；
15-20 parts of high efficiency water reducing agent；
30-40 parts of calcium carbonate；
5-8 parts of potassium sulfite；
15-20 parts of di-iron trioxide；
5-6 parts of slag；
2-3 parts of anhydrous sodium metasilicate.
Further, wherein the particle radius of 1 quartz sand of claims is 1.5-4mm.
Further, wherein water-reducing agent described in claims 1 is poly- antelope acid water-reducing agent.
In raw material of the present invention, flyash is resourceful, cheap as a kind of industrial waste, and contains a large amount of glass
Change microballon.Glass bead has ball bearing effect, can reduce the frictional force between cement granules, improve the flowing of concrete
Property, and its large specific surface area, surface energy are high, and the ability for adsorbing water is small；Glass microballoon can also strengthen sun reflection and convection current
Heat transfer, to trap heat, by the notable resistance strengthened solar heat reflection and transmitted to heat, reaching reduces body surface
Thermal equilibrium temperature can make exterior wall temperature reduce heat insulation notable.
Unique Wuli-Shili-Renli system approach possessed by quartz sand so that it is in Aeronautics and Astronautics, electronics, machinery and current
Occupy very important status in the IT industry of rapid development, becomes in molecular chain structure, crystal shape and lattice especially in it
Law, the high temperature resistant made it have, coefficient of thermal expansion be small, high-insulation, corrosion-resistant, piezoelectric effect, resonance effect and its
Unique optical characteristics plays more and more important in many high-tech products.Quartz sand is 1.5- by being finely ground into radius
It is very helpful to the intensity of cement after the particle of 4mm.
Diminishing agent molecule energy oriented attachment keeps cement particle surface (usual with same charge in cement particle surface
For negative electrical charge), electrostatic repulsion is formed, cement granules is promoted mutually to disperse, flocculent structure is destroyed, and wrapped part is released
Water participates in flowing, to effectively increase the mobility of mortar.
The present invention is maximized favourable factors and minimized unfavourable ones by reasonable preparation material rate, and function admirable, flexible, resistance to deformation energy are obtained with this
The cement that power is strong, freezing tolerance is strong.
So the cement come out using the recipe configuration in the present invention is good, flexible with barrier properties, non-deformability is strong,
The advantages that freezing tolerance is strong, easy for installation, comprehensive cost low.
