Abstract
The invention discloses an air-added brick with slag as matrix and a method for processing the same. The air-added brick is composed of the raw materials according to parts by weight: 10-15 parts of iron ore tailings, 5-10 parts of phosphorus slag, 10-20 parts of blast furnace slag, 10-15 parts of vanadium ore tailings, 5-8 parts of cement, 5-10 parts of kaolin, 14-16 parts of expanded perlite, 4-5 parts of ceramic clay, 0.03-0.05 part of aluminum powder, 5-10 parts of modified plant ash, 0.03-0.04 part of oxidated paraffin soap, 0.01-0.02 part of aluminium hydroxide, 0.01-0.02 part of water glass and 0.3-0.5 part of ultrafine polyvinyl alcohol. The air-added brick employs the slag as the matrix thereof, so that the environmental pollution is effectively reduced, the waste material is changed into things of value and the environment is protected; the energy consumption is reduced; the air-added brick is excellent in both of heat insulation and sound insulation properties and is obviously improved in contrast with the existing air-added brick; and simultaneously, the air-added brick is obviously improved in strength and freezing resistance by optimizing the materials in the formula.
Description
Technical field
The present invention relates to building material field, specifically belong to a kind of aerated bricks and working method thereof take slag as matrix.
Background technology
Aerated bricks is the aerated bricks building block of producing by autoclave at high temperature apparatus and process, adopt the brick product of other the various explained hereafter including steam pressure, aerated bricks is a kind of novel wall material, its unique distinction is that it is a kind of novel building walling of very light-duty heat insulating, and that this technology of China starts is more late, than abroad, totally fallen behind 40 years, but, the development of the aerated bricks industry of China is really very fast, and domestic aerated bricks technical matters level can reach international most advanced level now.
Aerated bricks sharpest edges economize the land resource exactly, need not waste a large amount of arable lands, and the source of its raw material very extensively, dust and sand, slag, flyash and coal gangue etc. are all the starting material that do aerated bricks, and very superior of the characteristic of property of aerated bricks, have extraordinary can working ability and heat insulation and insulated capacity, and very strong of plasticity-, have extraordinary processing characteristics, the research of aerated bricks raw material and processing technology need further to improve.
Summary of the invention
The object of the present invention is to provide a kind of aerated bricks and working method thereof take slag as matrix, slag consumption is large, energy-conserving and environment-protective, alleviates slag and stores up the problem of environmental pollution that processing brings, simultaneously for aerated bricks provides new raw material sources.
The present invention adopts following technical scheme to achieve these goals:
Aerated bricks take slag as matrix, the weight part of its constitutive material is: iron ore tailings 10-15, phosphorus ore slag 5-10, blast-furnace slag 10-20, alum ore deposit tailings 10-15, cement 5-8, kaolin 5-10, pearlstone 14-16, ceramic clay 4-5, aluminium powder 0.03-0.05, modification plant ash 5-10, oxidized paraffin wax soap 0.03-0.04, aluminium hydroxide 0.01-0.02, water glass 0.01-0.02 and micronized polyethylene alcohol 0.3-0.5.
The working method of the aerated bricks take slag as matrix, comprises the following steps:
(1) raw-material processing: starting material comprise iron ore tailings, phosphorus ore slag, blast-furnace slag, alum ore deposit tailings, cement, kaolin, pearlstone, ceramic clay and aluminium powder; Be crushed to fineness and reach 180-200 order;
(2) stir: Xian Jiashui stirs separately, then mix and blend also adds other surplus stocks in raw material by weight;
(3) cast: the slurry that step (2) is stirred adds in stock mould, obtains brick idiosome;
(4) rest: the brick idiosome of step (3) is put into the chamber of resting, the chamber sealing thermal insulation 40-45 ℃ that rests, time 1-3 hour rests;
(5) cutting: the brick idiosome that step (4) is rested is put into and is processed into certain desired size on cutting machine;
(6) steam-cured: the green compact of above-mentioned steps (5), at 0.8-1.0Mpa vapor cure 16-19h, are obtained to aerated bricks finished product.
Modification plant ash is plant ash to be admixed to be equivalent to the calcium lignin sulphonate agitating with dibutyl maleinate, 1-2% of powder weight 1-2% even, dries, and is ground into powder and obtains.
Beneficial effect of the present invention:
The present invention, by adopting the composition of slag as aerated bricks, has effectively reduced environmental pollution, turns waste into wealth, and has protected environment; Reduced energy consumption; Aerated bricks of the present invention is heat insulation all good with sound-proofing properties, and more existing aerated bricks is significantly improved; The present invention is simultaneously by optimization of C/C composites materials, and intensity of the present invention, frost resistance are significantly improved.
