Description
Technical field
The present invention relates to environment-friendly type building Material Field, and in particular to a kind of light-weight aggregate bend resistance concrete.
Background technology
Since concrete has the characteristics that abundant raw material, cheap, simple production process, Contemporary Architecture neck is become
One of mostly important material in domain, thus concrete makes its dosage increasing.In addition, the high epistasis of concrete, high tenacity,
High cracking resistance, high-durability and lightweight are development trend of the following civil construction field to concrete material performance requirement.Mesh
The normal concrete applied in preceding civil engineering is a kind of quasi-brittle material, although the polymer such as incorporation suitable fibers are in certain journey
Improve its tension, bending strength and fracture property on degree, but to face chronic anti-aging performance bad for polymer in concrete
The problem of.And the problems such as mass per volume of normal concrete is big, heaviness, its use is restricted in all various aspects,
Increase the loss of human and material resources.
With the development of industry, a large amount of coals are burned off therewith, and flyash is as a kind of solid waste, with coal
The flue gas emissions that generate of burning and into air.The useful moneys such as a large amount of silica and alundum (Al2O3) are included in flyash
Source, if it not being collected and being dealt carefully with, it will cause the wasting of resources and environmental pollution.Therefore the comprehensive profit of flyash
With turning waste into wealth, it has also become an important techno-economic policy in economic construction of China is to alleviate China's environmental pollution pressure
Power, the important means of resource shortage.The microscopic pattern of flyash is hollow ball structure, and this give flyash quality is light, density
Low physical characteristic, the present invention make full use of the physicochemical properties of flyash, be prepared for it is a kind of have lightweight, high epistasis,
High tenacity, high cracking resistance, high-durability concrete.
103951459 A of China Patent Publication No. CN provide a kind of utilization lytag and prepare foaming water for lightweight aggregate
The method of mud：The detailed process is step, and shuttle sodium carboxymethylcellulose pyce is added to the water dissolving, it is water-soluble to obtain shuttle sodium carboxymethylcellulose pyce
Liquid step adds in poly-vinyl alcohol solution into above-mentioned solution, stirs evenly, and then, while agitating, sequentially adds flyash
Haydite and mixture, stir evenly, and finally, hydrogen peroxide are added in into the slurry being uniformly mixed, quick to stir, and enter mould, harden
Molding, final set, demoulding, the water spray of moisturizing indoors or covering membrane curing extremely test age to get lytag foam cement.
The present invention improves weak area between aggregate and cement mortar by adding shuttle methylcellulose sodium salt, improves open-minded knotting strength,
The mechanical property and durability for making foam cement significantly improve, and solve the problems, such as haydite floating.The invention is fine using shuttle methyl
For the plain sodium salt of dimension as a kind of primary raw material therein, poor air permeability after leading to this cement applications in building makes entire cement
Coating rate of drying is slow, delays construction speed.
China Patent Publication No. CN1491917A is related to a kind of preparation method of high strength lightweight aggregate concrete, it is characterized in that：
It is realized by following steps：1) pretreatment of light-weight aggregates：A) preparation of pretreated waters slurry body, pretreated water slurry body is by water
Mud, super fine powder additives, water-soluble polypropylene yogurt liquid, water-reducing agent FDN, water composition；B) light-weight aggregate is put into above-mentioned pretreated water by
It is taken out after stirring 1~3min in slurry body, conserves 1~3 day under the conditions of relative humidity 90 ± 5%, 20 ± 3 DEG C of temperature, for use；
2) preparation of light aggregate concretes：High strength lightweight aggregate concrete by pretreated light-weight aggregate, cement, fine aggregate, silicon ash, subtracts
Aqua FDN, water composition；It stirs evenly in proportion and slurry is made to get product.It can effectively improve light-weight aggregate granule strength,
Water absorption rate is reduced, dramatically increase light aggregate concrete intensity and improves light aggregate concrete pumping workability.It is prepared by this method
Time length, complex process, used super fine powder additives will pass through ball milling repeatedly, and manufacturing cost is high, high energy consumption, be unfavorable for industry
Change large-scale production.
China Patent Publication No. CN102795878A is related to a kind of light thermal insulation foam cement and preparation method thereof, mainly with
