Abstract
The invention relates to a thermal insulation foam concrete preparation process applying andesite rock powder. The raw materials comprise: 520 parts by weight of water, 300 parts by weight of cement, 420 parts by weight of fly ash, 420 parts by weight of andesite rock powder, and 310 parts by weight of an activator mixed solution. The preparation steps include: stirring water, Portland cement, fly ash and andesite rock powder into a cement slurry according to the proportion; preparing the activator mixed solution from an activator and water in a weight ratio of 10:300, placing the mixed solution in a bucket, mixing compressed air with the activator mixed solution through an air compressor and a foaming machine to form high density bubbles, making the pressure of an air pump reach 0.8MPa; and then mixing the cement slurry with the high density bubbles in a stirrer through the hydraulic pressure of the foaming machine, and finally delivering the product to a specified place through a high pressure pipeline. The thermal insulation foam concrete involved in the invention can completely replace ceramsite concrete, expanded perlite and other traditional thermal insulation and filling materials, can realize continuous casting construction on the spot, and is convenient, fast, economical, and environment friendly. The thermal insulation foam concrete prepared by the invention can be widely applied to roof sloping, leveling, thermal insulation, basement bottom plates, tops plates, bridges and many other fields.
Description
Technical field
The present invention relates to construction craft technology, building material field, particularly a kind of insulating foam concrete preparation technology who applies andesite stone flour.
Background technology
Foamed concrete is used in roof slope making, insulation, filling at present in a large number, and traditional foamed concrete is produced with cement in a large number, and overall cost is high.
And andesite belongs to a kind of of volcanic rock, be to manufacture one of concrete good aggregate.Main waste-the stone flour of stone ore, contaminate environment, farmland, river.For the comprehensive utilization of resource, in conjunction with andesite self character, this kind of stone flour is applied to the preparation of foamed concrete.
Summary of the invention
The object of the present invention is to provide a kind of insulating foam concrete preparation technology who applies andesite stone flour, it mainly solves the existing problem of above-mentioned prior art, and it can substitute tradition insulation, the packing materials such as haydite concrete, pearlstone completely; At the scene can continuous placing construction, convenient, fast, economy, environmental protection.The present invention can be widely used in roof slope making, levelling, insulation, basement bottom board, top board, a lot of fields such as bridge.
The present invention solves the problems of the technologies described above adopted technical scheme:
An insulating foam concrete preparation technology for andesite stone flour, is characterized in that: its raw material comprises water 520 weight parts, cement 300 weight parts, flyash 420 weight parts, andesite stone flour 420 weight parts and exciting agent mixed solution 310 weight parts;
Its preparation process is: by cement elevating hopper and water pump, expect in agitation vat in proportion on together with water, silicate cement, flyash, andesite stone flour, and stirred into cement slurry; The exciting agent and the water that form exciting agent mixed solution are pressed in the good storing barrel of part by weight proportioning of 10: 300, by air compressor machine, pressurized air and exciting agent mixed solution are mixed to form to high-density bubble by foaming machine, and the pressure of air pump need to reach 0.8Mpa; Then the hydraulic pressure by foaming machine mixes cement slurry and high-density bubble in agitator, finally by pressure piping, is transported to appointed part.
The insulating foam concrete preparation technology of described application andesite stone flour, is characterized in that: the aggregate size of described flyash and andesite stone flour need be less than 5mm and be greater than 0.075mm.
The invention has the beneficial effects as follows:
1, because andesite stone flour is rich in Al
2o
3(approximately 18%), has early strength function, can effectively improve early powerful feature of foamed concrete, also has heat-insulating property concurrently.Because andesite stone flour is rich in SiO
2(approximately 50%), can effectively improve foamed concrete intensity.
2, in cement admixture, adopt in a large number the stone powder waste materials of stone ore factory, the starting material such as flyash in power station, and take novel process, and form insulating foam concrete, in roof slope making, insulation, in the numerous areas such as highway, bridge, floor heating, Abutment Back, apply new blending process and new construction, realize the zero release that stone ore factory waste stone dust is recycled, thereby greatly reduce carrying capacity of environment and environment for human survival is polluted.
Embodiment
The invention discloses a kind of insulating foam concrete preparation technology who applies andesite stone flour.Raw material in this technique comprises water 520 weight parts, cement 300 weight parts, flyash 420 weight parts, andesite stone flour 420 weight parts and exciting agent mixed solution 310 weight parts; Its preparation process is:
By cement elevating hopper and water pump, on together with water, silicate cement, flyash, andesite stone flour, expect in agitation vat in proportion, and stirred into cement slurry; The exciting agent and the water that form exciting agent mixed solution are pressed in the good storing barrel of part by weight proportioning of 10: 300, by air compressor machine, pressurized air and exciting agent mixed solution are mixed to form to high-density bubble by foaming machine, and the pressure of air pump need to reach 0.8Mpa; Then the hydraulic pressure by foaming machine mixes cement slurry and high-density bubble in agitator, finally by pressure piping, is transported to appointed part.
In the present invention, the aggregate size of described flyash and andesite stone flour need be less than 5mm and be greater than 0.075mm.
In the present invention, described exciting agent is from the buying of Yantai Lan Hai building material company limited, and the whipping agent that model is F-400, also can adopt other similar exciting agent.
When the product of technique of the present invention is used, because foamed concrete drying shrinkage is larger, in condensing process, easily ftracture, therefore watered after 12 hours often water seasoning, 3-5 the number that water every day guarantees that light-weight foamed concrete is in moisture state, curing time must not be less than 7 days, guarantees that the process of aquation does not ftracture.The present invention can be applied in decoration integrated body of wall, roof slope making, insulation, in the numerous areas such as combined wall board, floor heating, filling, bridge.Handicraft product is a kind of novel A level noncombustible construction energy-conserving and environment-protective material.
In sum, be only preferred embodiment of the present invention, be not used for limiting practical range of the present invention, i.e. all equivalences of doing according to the content of the present patent application the scope of the claims change and modify, and all should be technology category of the present invention.
