Abstract
The invention provides a porous lightweight slag brick which is prepared by steps of preparation of slag powder, preparation of slag concrete, foaming of the slag concrete, forming of a slag brick, maintenance of the slag brick and surface-layer reinforcing of the slag brick. Slag can be made into the porous lightweight slag brick which is used for masonry of buildings. The porous lightweight slag brick has the advantages of light weight, porousness, heat insulation, high strength and suitableness for being used as wall building materials.
Description
Technical field
What the present invention proposed is the materials for wall of building material field, specifically the light body slag brick of a kind of porous.
Background technology
The existing material that is used for building wall mainly is brick, is used for the partition in room and the filling of skeleton construction and builds by laying bricks or stones.Existing brick has vitrified brick and non-burning brick.Vitrified brick has common brick, hollow common brick; Non-burning brick have cinder brick, a sandstone brick, also has the hollow clinker brick.From structure, no matter have is solid brick and hollow brick, although adopted cinder or slag, basically all produces in concrete mode.Usually all need to make its moulding under the condition of pressure in process of production, therefore, degree of compactness is high, and porosity is low, so that unit weight is large, heat preservation and insulation is not good, therefore uses also to be restricted.Along with extensive common recognition and the policy needs of energy-conserving and environment-protective theory, the material of construction of seeking the light heat-insulating insulation is the demand of technical progress.
The slag of Iron-ore Slag, Copper Slag and other dressing-works output is waste product, by stacking or burying and process, and not only land occupation resource, also contaminate environment.And the pollution and the environment that utilize slag production material of construction can alleviate slag take, and can turn waste into wealth, and again for building field provides valuable material of construction, can play the effect of achieving many things at one stroke simultaneously.
In sum, utilizing the light walling material of slag and gelling material and whipping agent manufacturing is the problem that needs research.
Summary of the invention
In order to utilize slag and gelling material and whipping agent to make light body porous wall material of construction, the present invention proposes the light body slag brick of a kind of porous.This slag brick is take slag as the physique material, by with the mixing of adhesive material and whipping agent, foaming at normal temp, blanks and moulding and conserving becomes finished product, solves to utilize slag to make the technical problem of the light body slag brick of porous.
The scheme that technical solution problem of the present invention adopts is:
1, the preparation of slag powders:
Carry out slag according to the slag of the different mineral of mine, location institute output and select, then further be crushed to 200～300 orders through pulverizer, then screening is got the lower slag powders of sieve, as the physique material of slag brick.
2, the preparation of slag concrete:
By mass percentage, get 2 parts of silicate cements, with 1～2 part of slag physique material mixing, add 1～2 times of part of water in the total mass material that forms, make slag concrete after the stirring.
3, the foaming of slag concrete:
Adding quality in 1 part of slag concrete is 0.1～0.3 part of 30% polyvinyl alcohol glue than content, adds 0.1 part in 0.1～0.8% part of aluminium powder or hydrogen peroxide again, by stirring, becomes the slag foamed concrete.
Aluminium powder is flakey, and granularity is between 0.01～0.2 millimeter, and hydrogen peroxide oxygen level mass percent is between 28～30%.
4, the moulding of slag brick:
The slag foamed concrete is injected in the mould curing molding under the normal temperature.
5, the maintenance of slag brick:
The slag foamed concrete of curing molding is tripped out from mould, and layering is deposited on the nursing frame, and nursing frame is placed plastic greenhouse, regularly sprays water earthward, keeps on the ground water being arranged, and humidity reaches 100%.Through maintenance in 28 days, become slag brick.
6, the top layer of slag brick strengthens:
Slag brick be impregnated in mass percent 30% grout 2 minutes, pull out, deposited at normal temperatures 2～3 days, become the finished product slag brick.
Positively effect because the present invention can make slag the light body slag brick of porous, is used for building by laying bricks or stones of buildings.Have light weight, porous, heat insulation, insulation, characteristics that intensity is high.Suit to use as wall body building material.
Embodiment
1, the preparation of slag powders:
Carry out slag according to the slag of the different mineral of mine, location institute output and select, then further be crushed to 200～300 orders through pulverizer, then screening is got the lower slag powders of sieve, as the physique material of slag brick.
2, the preparation of slag concrete:
By mass percentage, get 2 parts of silicate cements, with 1～2 part of slag physique material mixing, add doubly part of water 1-2 in the total mass material that forms, make slag concrete after the stirring.
3, the foaming of slag concrete:
Adding quality in 1 part of slag concrete is 0.1～0.3 part of 30% polyvinyl alcohol glue than content, adds 0.1 part in 0.1～0.8% part of aluminium powder or hydrogen peroxide again, by stirring, becomes the slag foamed concrete.
Aluminium powder is flakey, and granularity is between 0.01～0.2 millimeter, and hydrogen peroxide oxygen level mass percent is between 28～30%.
4, the moulding of slag brick:
The slag foamed concrete is injected in the mould curing molding under the normal temperature.
5, the maintenance of slag brick:
The slag foamed concrete of curing molding is tripped out from mould, and layering is deposited on the nursing frame, and nursing frame is placed plastic greenhouse, regularly sprays water earthward, keeps on the ground water being arranged, and humidity reaches 100%.Through maintenance in 28 days, become slag brick.
6, the top layer of slag brick strengthens:
Slag brick be impregnated in mass percent 30% grout 2 minutes, pull out, deposited at normal temperatures 2～3 days, become the finished product slag brick.
Advantage of the present invention:
1, slag brick physique material adopts mine solid waste, wide material sources, and cost is low, and can also environmental contamination reduction and appropriation of land, and can alleviate the river course and stop up, and is conducive to flood control.
2, with cement as tackiness agent, material is sufficient, cost is low, made slag brick intensity is high.
3, adopt aluminium powder or hydrogen peroxide as whipping agent, wherein: the aluminium powder foaming is stable, aluminium powder can react with cement neutral and alkali composition, produce aluminum oxide and hydrogen, hydrogen is surrounded by concrete, forms bubble, mutually solidify between bubble and the bubble, form a plurality of blind holes, in the hole, be filled with air, by mutually completely cutting off of air, produce effect heat insulation and insulation, and light unit weight, so unit weight is little, wherein: after hydrogen peroxide touches the organic or inorganic material, produce oxygen, oxygen produces bubble in concrete, bubble stabilizes forms the hollow structure body of uniform concrete involucrum.
4, the slag brick after blanks and moulding and conserving can make the pore sealing on slag brick surface through the dip treating of grout, stops airiness, produces good heat preservation and insulation.And, can also strengthen the surface strength of slag brick, be conducive to loading and unloading and building wall.
