Description
Technical field
The invention belongs to building materials technology field, relate to a kind of utilize cullet to produce autoclave aerated concrete building block and production method.
Background technology
Along with the raising day by day with living standards of the people that develops rapidly of science and technology, glass is not only widely used among the daily life of building construction and the people, and becomes the indispensable material of research and production.And in glass use procedure, simultaneously inevitably produce many glass wastes, form a large amount of cullet.According to conservative estimation, cullet accounts for 5% of total amount in domestic refuse, and the cullet that only sheet glass production produces every year just reaches more than 200 ten thousand tons, forms huge waste resource.Category of glass chemistries is stablized, and without putrefaction, does not burn, can not degrade, and a large amount of cullet brought inconvenience both to the production of people and life, created load again to environment.Therefore, how to carry out cullet resource and change into a current problem demanding prompt solution.
Summary of the invention
The object of the invention is to for prior art Problems existing, a kind of method utilizing cullet to produce autoclave aerated concrete building block is provided, effectively realizes the recycling of cullet, the performance of autoclave aerated concrete building block can be improved simultaneously.
For this reason, the present invention adopts following technical scheme:
Utilize cullet to produce a method for autoclave aerated concrete building block, be made up of the raw material of following weight part: desert fine sand 60-80 part, cement 5-10 part, unslaked lime 10-20 part, cullet 5-10 part, aluminium powder cream 0.05-0.10 part; Concrete preparation process is as follows:
(1) desert fine sand and cullet grinding of ball grinder are made as the powder of granularity below 200 orders, then for subsequent use with hollander making beating;
(2) by unslaked lime crusher in crushing, then the powder of granularity below 160 orders is made as with grinding of ball grinder;
(3) the desert fine sand after making beating and waste glass powder, unslaked lime after ball milling are added water in stirrer with cement and aluminium powder cream and fully stir, obtain compound, control amount of water makes the ratio of water to material of compound be 0.5-0.7:1;
(4) compound is molded into mould, the mould of having cast is pushed in initial set curing room and carries out initial set, obtain large building block base substrate;
(5) large building block base substrate is cut, obtain standard-sized building block base substrate, building block base substrate is pushed indoor of resting and carry out quietly stopping maintenance;
(6) quiet stopping is carried out steam press maintenance in the feeding of the building block base substrate after maintenance autoclave, after steam press maintenance terminates, namely obtain product concrete segment.
Further, described raw material also comprises straw powder 1-3 part, and the granularity of straw powder is 30-60 order; During preparation, in step (3), the desert fine sand after making beating and waste glass powder, unslaked lime after ball milling and cement, aluminium powder cream and straw powder are added water in stirrer and fully stirs, obtain compound.
Further, described raw material also comprises waste cotton wadding 2-5 part, during preparation, by waste cotton wadding cotton fluffer bullet to completely fluffy, then in step (3), desert fine sand after making beating and waste glass powder, unslaked lime after ball milling and cement, aluminium powder cream, straw powder and waste cotton being wadded a quilt with cotton adds water in stirrer fully stirs, and obtains compound.
In the present invention, in Arid Desert Region, desert fine sand is cheap and easy to get, can gather materials on the spot, arable land can not be destroyed, and desert fine sand fineness is little, eliminates the workload of screening, series of advantages such as having lightweight simultaneously, intensity is high, thermal conductivity is little, frost resistance, anti-carbonation properties are good, effectively improves crushing resistance and the heat retaining property of concrete segment.Cullet effectively can substitute fine sand after grinding, and has the feature of light weight, and can be used as concrete fine aggregate to a certain extent, increases the ultimate compression strength of concrete segment.Containing higher vegetable fibre in straw powder, after being added into concrete, effectively can improving the folding strength of concrete segment, and alleviate concrete gravity.
In addition, annual China all can produce a large amount of waste cotton fiber, if can not get effective utilization, has quite a few waste cotton fiber can be used to make shoddy cotton, harm consumer health.Compared to straw powder etc., the fibre content of cotton is higher, staple length is longer, the present invention makes full use of this feature of cotton, adds in other raw material and jointly prepares concrete segment, cotton fiber can be made to be evenly distributed in concrete segment after fully stirring after waste cotton fiber bullet is extremely completely fluffy, tensile property and the fracture resistance of concrete segment can be significantly improved, and add as material of construction, not high to the quality requirements of cotton, efficiently solve waste cotton fiber and reclaim difficult problem.
To sum up, beneficial effect of the present invention is: take full advantage of the solid waste such as cullet, straw powder, waste cotton wadding, achieve the regeneration of waste and old resource, and effectively improve the ultimate compression strength of concrete segment, tensile strength, folding strength and heat-insulating property.
