Abstract
A kind of recycling method of caused solid waste in being produced the invention discloses steam pressure sand aerated concrete block, dry grinded it is characterized in that entering ball mill together with lime after solid waste is crushed, cementitious matter is obtained, is used in autoclave aerated concrete building block is produced by the use of quality such as cementitious matters instead of lime as calcareous material.The present invention realizes the recycling of solid waste, reduces production cost, reduces the solid waste accumulation place of factory, mitigates solid environmental pollution, have good environment protecting.
Description
Technical field
The recycling of caused solid waste in being produced the present invention relates to a kind of steam pressure sand aerated concrete block
Method, in particular it is a kind of production method that steam pressure sand aerated concrete block is produced using solid waste.
Background technology
Steam pressure sand aerated concrete block is a kind of construction material, and it is with siliceous material (quartz sand) and calcareous material
(lime and cement) is primary raw material, and the loose structure of chemical gas generation method formation is passed through using aluminium powder cream as foaming agent, passes through steaming
Pressure maintenance completes hydrothermal synthesis reaction so as to obtain the silicate concrete building block of the physical and mechanical properties such as certain compression strength.Steam
Press sand aerated concrete block in process of production because the poor prognostic causes such as technique, operation, machinery produce waste product, generally will be this
Waste product is referred to as solid waste, and the essence of this solid waste and steam pressure sand aerated concrete block is identical, and it is led
Wanting composition is：CaO-SiO2-H2O systems, CaO-Al2O3-H2O systems, CaO-Al2O3-SiO3-H2O systems, CaO-Al2O3-
CaSO4-H2O systems.This solid waste can do insulation material, but doing insulation material merely far can not be consumed,
This solid waste is deposited in stockyard and not only wasted for a long time stacks place, also creates a kind of environmental pollution.
The content of the invention
The present invention is to avoid the weak point present in above-mentioned prior art, there is provided a kind of steam pressure sand aerated concrete is built
The recycling method of caused solid waste in block production.
The recycling method of caused solid waste in steam pressure sand aerated concrete block production of the present invention, it is special
Point is：Solid waste is added in lime and obtains cementitious matter, by cementitious matter, cement, quartz sand, foaming agent and foam stabilizer
Be added to according to certain proportioning in agitator tank, by cast, it is quiet stop being molded, cut, steam press maintenance, produce steam pressure sand aerating
Concrete segment.
The recycling method of caused solid waste in steam pressure sand aerated concrete block production of the present invention, it is special
Point is to carry out as follows：
(1) by solid waste be broken into particle diameter be not more than 50mm fragment, then according to lime weight 10%~
20% adds in ball mill together with lime and is dry grinded, and obtains the cementitious matter of 0.08mm square hole screen screen over-size≤15%；
(2) by 0.08mm square hole screens screen over-size≤25%, the quartz sand of silicon content 91~98% and powdery ardealite according to
Mass ratio 35:1 adds water mixing, and 1.54~1.58kg/L of proportion mixed mortar is made；
(3) by 78.65~79.65 parts of mixed mortar, 10.48~11.1 parts of cementitious matter, 6.64~9.25% parts of cement：Hair
0.06 part of 0.617~0.647 part of gas agent and foam stabilizer are sequentially added in agitator tank, are stirred, and obtain mixing cast slurry；
(4) mixing is poured into a mould into slurry to stop being molded, cut, steam press maintenance through quiet, obtains steam pressure sand aerated concrete and build
Block.
Compared with the prior art, the present invention has the beneficial effect that：
1st, primary raw material of the present invention by the use of solid waste as production steam pressure sand aerated concrete block, solid waste
Not directly participate in hydration reaction, mainly by the use of its internal structure stability as react aggregate, be filled in steam pressure sand
In production process of gas concrete inside hydrated product, the stability of aggregate needed for whole hydration reaction is improved.
2nd, the present invention realizes solid waste and recycled and turns waste into wealth, and not only solves solid waste stacking and asks
Topic, more solves the puzzlement of solid waste environmental pollution.
Embodiment
The working system of solid waste production steam pressure sand aerated concrete block, technological process are utilized in the embodiment of the present invention
Including solid waste processing, mixed mortar makes, dispensing stirring, quiet stop being molded, cuts, steam press maintenance.It is produced by the invention
It is B06 level steam pressure sand aerated concrete blocks.
1st, solid waste is handled：Solid waste is broken into fragment of the particle diameter no more than 50mm by jaw crusher,
Dry grinded according to the 10-15% of lime weight together with lime into ball mill, the material gone out after mill is referred to as cementitious matter, and its is thin
≤ 15% (0.08mm square hole screens) is spent, cementitious matter is stored in cementitious matter storage tank and supplies production and application.
2nd, mixed mortar makes：Using fineness≤25% (0.08mm square hole screens), silicon content 91~98% quartz sand with
Powdery ardealite is according to 35:1 adds water mixing, and 1.54~1.58kg/L of proportion mixed mortar is made, is stored in mortar jar and supplies
Production and application.
3rd, dispensing stirs：By 78.65~79.65 parts of mixed mortar, 10.48~11.1 parts of cementitious matter, cement 6.64~
9.25 part：0.06 part of 0.617~0.647 part of aluminium powder cream and foam stabilizer (air entrained concrete special additive) sequentially add stirring
Tank, poured into a mould after stirring and enter mould vehicle.
4th, it is quiet to stop being molded：The interior mixing cast slurry of mould vehicle is by getting angry, being thickened, hardened forming, obtains hard with cutting
The base substrate of degree.
5th, cut：Specification as needed carries out rip cutting and crosscutting cutting to base substrate, and billet surface is removed after cutting
Leftover pieces, organize into groups into still kettle.
6th, steam press maintenance：Base substrate enters to start after still kettle steam press maintenance operation, (1) first to still kettle vacuum pumping,
Still kettle pressure was at the uniform velocity pumped into -0.06MPa at 20~30 minutes；(2) exhaust and boost operations are carried out after vacuum, 1.5~2 hours
