Description
Technical field
The present invention relates to a kind of buildings load-bearing or partition wall materials for wall and preparation method thereof, specifically, relate to a kind of polystyrene-flyash concrete materials for wall and preparation method thereof.Be used for the building material engineering technical field.
Background technology
Body of wall is the primary member of buildings, and it has load-bearing, the compartment, insulation, major function such as heat insulation.For thousands of years, body of wall is to be main raw with the sintered clay brick always.Sintered clay brick not only consumes a large amount of energy, and all will destroy a large amount of arable lands every year.Country has limited and has forbidden the use of clay brick in more than 160 the urban construction dwelling house in the whole nation, therefore be badly in need of the novel wall material of some substitute for clay bricks of development.The research worker of lot of domestic and foreign has carried out the research work of the research of this respect, and successfully sends some materials for walls.
Find through literature search prior art, patent publication No.: CN1463941A, patent name: multifunctional lightweight high-strength unburned brick, this patent mention the leca that adopts different-grain diameter, float pearl, flyash, white clay and modified water glass prepares a kind of baking-free lightweight engineering brick.This materials for wall has higher advantage such as fire-resistant, antiacid, wear-resisting and unburned, but its starting material that adopt are relatively more expensive and owing to adopted leca, it is bigger to exist the later stage shrinkability, easy to crack, should not be used for general covil construction.Some light wall materials that other is newly developed, as the cellular concrete light material, haydite concrete, flyash brick etc., but also all exist some defective and deficiency, limited these materials for walls and in modern construction engineering, used.Along with the increase of human environmental protection and energy saving consciousness, modern building requires not only lightweight, high-strength to materials for wall, and has good heat insulating soundproof effect.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art and defective, provide a kind of polystyrene-flyash concrete materials for wall and this distribution, make its light weight, intensity high and have the good heat insulating sound-proofing properties and characteristics of environmental protection and energy saving.
The present invention is achieved by the following technical solutions, component that material of the present invention comprises and weight percent thereof are: cement 25～30%, water 12～15%, flyash 5～10%, SILICA FUME 1～5%, polystyrene foam particles A 0.15～0.35%, polystyrene foam particles B 0.1～0.25%, coarse aggregate 44.4～52.13%.
Described polystyrene foam particles A diameter is 3.0mm, and apparent density is 20kg/m
3Spheroidal particle, described polystyrene foam particles B diameter is 8.0mm, apparent density is 8.5kg/m
3Spheroidal particle; Described coarse aggregate, particle diameter are the rubble of 10～20mm gap grading.
It is that the coarse aggregate of 10～20mm gap grading forms the intensity skeleton in the concrete mix that the present invention mainly utilizes particle diameter, in intensity skeleton internal voids, fill the polystyrene foam particles of different-grain diameter, reduce the deadweight of concrete mix and improve its heat insulating sound-proofing properties, improve polystyrene foam particles and cement slurry cohesive force by the admixture SILICA FUME simultaneously.For realizing Sustainable development and reducing cost, in mix, mix a large amount of flyash, reach simultaneously and improve the mix workability and be easy to casting.
The preparation method of polystyrene of the present invention-flyash concrete materials for wall, by polystyrene foam particles, flyash, SILICA FUME and particle diameter is that to add in proportion that water is mixed with mix and utilizes the prefabricated mould casting be the standard square or the building block of different intensity grades for the coarse aggregate of 10～20mm gap grading, mix and stir casting in the following order: 1. cement, flyash and SILICA FUME were carried out dry mixing 1 minute, add 40% water and stirred 2～3 minutes; 2. add polystyrene foam particles A and B, stirred 3 minutes; 3. add coarse aggregate, its churning time is 15 seconds～1 minute, adds remainder water at last, stirs into concrete mixture, and its churning time is 2～3 minutes.
The present invention has following feature performance benefit: technology is simple, and is easy to operate, can make the sample of different size and specification; Lightweight, high-strength, insulation, heat insulation and sound insulation; Have higher volume stability, do not have and shrink; Low price has the value of environmental protection.
Embodiment
Provide following examples in conjunction with content of the present invention:
Polystyrene---flyash concrete materials for wall, by polystyrene foam particles, flyash, SILICA FUME and particle diameter is that the coarse aggregate of 10～20mm gap grading is by suitable proportion, finish with following processing method: will carry out dry mixing 1 minute by cement, flyash and the SILICA FUME of proportioning design requirements earlier, and add 40% water and stirred 2～3 minutes; Add polystyrene foam particles A and B then, stirred 3 minutes; Add coarse aggregate subsequently, its churning time is 15 seconds～1 minute, adds remainder water at last, stirs into concrete mixture, and its churning time is 2～3 minutes.With the concrete mixture that the stirs prefabricated mould casting of packing into is the standard square or the building block of different intensity grades.During cast, can directly mix be cast in the ganoid bed die, also can pour into a mould in the demoulding of mold bottom place mat earlier.The curing in the mold cycle is 1～2 day, takes off that to touch curing cycle be 14～28 days.But high-strength light materials for wall of the present invention also cast-in-place is shaped to design shape.The weight percent of the polystyrene-flyash concrete materials for wall component concentration of preparation is as follows:
| Sample | Cement | Flyash | SILICA FUME | Water | Particle A | Particle B | Coarse aggregate |
