Abstract
The invention discloses an autoclaved aerated concrete brick, belongs to a building material, and aims to provide an aerated concrete brick, which adopts phosphorus slag as a main raw material. The autoclaved aerated concrete brick is prepared from the following raw materials in percentage by mass: 49-55% of phosphorus slag, 21-26% silicon sand, 18-22% of quicklime, 3-9% of cement, 1-3% of gypsum and 0.04-0.06% of aluminum paste. A preparation method of the autoclaved aerated concrete brick comprises the following steps: grinding the quicklime and the gypsum into a cementing material; conducting wet grinding on the phosphorous slag and the silica sand to form a slurry; adding water into the aluminum paste to form aluminum slurry; thoroughly mixing the slurry, the cement, the cementing material and water, and then adding the aluminum slurry; feeding steam for heating; pouring the castable into a mold; feeding to a curing room for curing; feeding the adobe to a still kettle, and feeding steam for heating; keeping the temperature and pressure for hours; reducing the temperature in the still kettle to 45-50 DEG C within 100 minutes; taking out the adobe. Test results show that the strength and density of the autoclaved aerated concrete brick both accord with relevant national standards and can replace a solid clay brick.
Description
Technical field
The present invention relates to a kind of concrete brick, relate in particular to a kind of steam-pressing aero-concrete brick.
Background technology
Gas concrete brick is lightweight because having, heat-insulating property and sound-absorbing effect good and have plurality of advantages such as some strength, become substitute traditional solid clay brick and obtained extensive utilization gradually.At present, the raw materials for production of the gas concrete fragment of brick that construction market adopts mainly be take flyash as main, and powdered coal ash supply is limited, causes the output of existing gas concrete fragment of brick limited, cannot meet the demand of construction market.If can develop a kind of trade waste of take---the gas concrete brick that phosphorus slag is main raw material, not only can reduce costs, widen the raw material sources of gas concrete brick, be more mainly can effectively consume phosphorus slag and reduce and stack place, economize the land resource and improve environment, can there is good economic benefit and social benefit undoubtedly.
Summary of the invention
For the above-mentioned defect existing in prior art, the present invention aims to provide a kind of steam-pressing aero-concrete brick that phosphorus slag makes as main raw material of take.
To achieve these goals, the present invention is by the following technical solutions: it is made by the raw material of following mass percent: phosphorus slag 49～55%, silica sand 21～26%, unslaked lime 18～22%, cement 3～9%, gypsum 1～3%, aluminium powder cream 0.04～0.06%, CaO, SiO in described phosphorus slag
2content sum be greater than 85%, the fineness of described unslaked lime is that 0.08mm sieve screen over-size is less than 10%; Its method is as follows:
1) unslaked lime and gypsum are mixed, grinding of ball grinder becomes agglutinate standby, guarantees that the specific surface area of agglutinate reaches 4000～6000 ㎝
2/ g;
2) phosphorus slag, silica sand are mixed, ball mill wet-milling form slurry is standby;
3) aluminium powder cream is added to water and stir, make aluminium powder cream slurry standby;
4) described slurry, cement, described agglutinate are mixed with water, uniform stirring 3 minutes, add described aluminium powder cream slurry, pass into steam and stirred for 30 seconds, obtain mould material;
5) mould material is entered to mould, send into the curing room maintenance 1～1.5 hour of 50 ℃, obtain large adobe;
6) by large adobe stripping and slicing on request, obtain adobe;
7) adobe is sent in the autoclave that pressure is-0.04～0.06Mpa, passed into steam, guarantee in 1.5～2 hours, to be warming up to more than 175 ℃; Constant temperature 5～7 hours, keeps pressure 0.8～1.2Mpa; Then in 100 minutes, temperature in the kettle is down to 45～50 ℃, takes out adobe.
In technique scheme, the oil-type aluminium powder cream that described aluminium powder cream is GLY75 >=75% or GLY65 >=65%, active aluminum >=90% in its solid, gas forming amount is that 4min is 50～80%, 16min >=90%, 30min >=99%.
Described aluminium powder cream can also adopt the water aqua type aluminium powder cream of GLS70 >=70%, GLS65 >=65%, active aluminum >=90% in its solid, and gas forming amount is that 4min is 40～60%, 16min >=90%, 30min >=99%.
Compared with the prior art, the present invention is due to technique scheme, take that when electric furnace process is produced yellow phosphorus, to produce shrend waste residue (phosphorus slag) be main raw material, and original trade waste is turned waste into wealth; Not only widen gas concrete brick raw material sources, reduced cost, and can also reduce and stack place by consuming phosphorus slag, saved land resources, reduced environmental pollution.
Detection shows, the intensity of fragment of brick of the present invention can reach A3.5, A5.0, A7.5, tetra-ranks of A10, and density reachable, to B05, B06, B07, tetra-ranks of B08, meets relevant national standard.
