Description
Technical field
The present invention relates to a kind of autoclave aerated concrete building block and preparation method thereof, belong to building material field.
Background technology
Polished tile is the brick of surface through a kind of light of polishing of all-body tile, and the weight that it occupies in Wall or floor tile is large, and value-added content of product is also high simultaneously, and in recent years, this product obtains swift and violent development.But polished tile can produce a large amount of polished waste materials in the process of grinding, polishing, this polished waste material granularity is very thin, in dispersion state after air-dry, very easily float down on the wind everywhere, understand the healthy of serious threat surrounding population, and cause the periphery hardening soil, but only serious environmental pollution.And the landfill of gun tube waste material, not only labor intensive, material resources, also can polluted underground water matter, people are called this phenomenon " White terror " usually.
For the application of polished waste material, mainly comprise several both at home and abroad below:
(1) polished waste material is utilized to produce light ceramic material
Directly utilize the principle that polished waste material at high temperature foams, with polished waste material be raw material introduce again some ceramic raw materials composition admixtion, then through shaping, burn till the operation such as (1200 DEG C), cutting produce light ceramic material.The pore of this light ceramic material inside is sealed porosity, utilize this feature of material, can be that light heat insulation material and sound-proof material use, but, due to the existence of the unburned material of low cost gas concrete, make this high-temperature firing brick because cost is high without place, cause all research to be only in theory stage, and without actual application value.
(2) polished waste material is utilized to produce decoration devitrified glass
The raw material of decoration devitrified glass is generally industrial tailings and slag, in addition, also will introduce a small amount of solubility promoter, finings and nucleator.The cost of product mainly concentrates on fusing and sintering cost, and raw materials cost proportion is less.And prepare with industrial tailings and slag the history that decoration devitrified glass has had more than 50 year, technology is very ripe, polished waste material mine tailing and slag are with belonging to industrial waste together, the meaning of waste material own is substituted just little with waste material, in addition technically not mature enough again, the more important thing is the consumption of polished waste material less.Therefore, produce decoration devitrified glass technology with polished waste material to be difficult to be widely applied.
(3) utilize polished waste material as cement mixing raw material
The people such as Su Genda, Wang Gongxun, Zhong little Min adopt composition and the Pozzolanic feature of the technique study such as X-ray analysis, amount of glassy phase and silicon, aluminum ions stripping quantity analysis industrial residue polishing brick dust.Result of study shows: polished tile powder volcanic ash stand the test, has certain latent hydraulicity, and its cement mortar 28 days compressive strength rates are 83.6%.The early activity of polished tile powder is higher than flyash.But cl content fluctuates within the scope of 0.011-0.203% in polished tile powder, its cl content is mainly from grinding head for polishing and flocculation agent.Polishing brick dust will be used as cement mixture, needs to control its cl content.And also containing some organic resin materials in some polished brick waste powder, these bring difficulty as the application of cement additive all to polished waste material.
(4) polished waste material and riverway sludge is utilized to produce sintered perforated brick
Utilize polished waste material and riverway sludge produce sintered perforated brick be one by the research be worth, mainly because its production technique is simple, production cost is low (sintering temperature is low: 900-1000 DEG C), product scale is large, have feasibility.But be subject to region restriction, and the utilization ratio of this method polished waste material is low (20-30%), and meanwhile, added value of product is relatively low.
Summary of the invention
The object of this invention is to provide the autoclave aerated concrete building block of a kind of environmental protection, energy-efficient, high-strength light, solve the problem that tile polished waste utilization ratio in the utilization of resources is low and environmental protection is not up to standard, the present invention provides its preparation method simultaneously.
Autoclave aerated concrete building block of the present invention, calculates with the building block of every cubic metre, comprises the raw material of following quality: lime 70-120Kg, cement 70-90Kg, aluminium powder 0.3-0.45Kg, ceramic polished waste material 250-400Kg.
The building block of every cubic metre also comprises gypsum 5-30Kg and suds-stabilizing agent 40-100g, the preferred phosphogypsum of gypsum or desulfurated plaster.
Wherein, the total mass of lime, cement, ceramic polished waste material is 485-525Kg.
Described autoclave aerated concrete building block can also comprise auxiliary agent, and auxiliary agent is one or both in kaolin 3-5Kg, wilkinite 3-5Kg.
Described lime is unslaked lime.
The special suds-stabilizing agent of gas concrete that described suds-stabilizing agent preferred Weihai Wei Peng lubricating oil company limited produces.
The preparation method of described autoclave aerated concrete building block, comprises the following steps:
(1) slurry is prepared:
Ceramic polished waste material is added water, makes water content reach 40-50%, stir, then add cement, lime successively, after stirring, leave standstill 5-10min, add aluminium powder and to stir standing 30-45s, make slurry;
(2) injection molding:
The slurry stirred is poured into a mould in progressive die tool;
(3) precuring:
At the temperature of 60-95 DEG C, leave standstill 1.5-3 hour, can cut;
(4) idiosome cutting:
Cutting machine carries out perpendicular cuts to idiosome two sides, then carries out vertical equity cutting to idiosome, finally carries out horizontal perpendicular cuts to idiosome;
(5) steam press maintenance:
Still steam press maintenance is entered to the idiosome of well cutting;
(6) still is gone out:
Finished product after steam press maintenance goes out still.
Preferred technical scheme is:
Step (1) is by ceramic polished waste material, gypsum mixing and stirring, adds water, makes water content reach 40-50%, stir, then add suds-stabilizing agent, cement, lime successively, after stirring, leave standstill 5-10min, add aluminium powder to stir standing 30-45s, make slurry.
