Abstract
The invention discloses an autoclave aerating stone powder block and manufacturing method, which comprises the following steps: allocating raw material with 65-68% stone powder, 25-29% limestone powder, 5-7% mineral slag powder, 0.5% aluminium powder and 0.5% waste gypsum; adding water into stone powder to stir into slurry; casting; moulding; insulating under normal temperature for 3h; cutting into brick with certain shape and regular; culturing brick in the autoclave; decompressing; obtaining the product.
Description
Technical field:
The invention belongs to building material technical field, relate to a kind of autoclaved aerated building block specifically.
Technical background: at present, various autoclaved aerated building blocks of the prior art mainly all are the concrete segments that is made by materials such as sandstone, cement, lime-ash.And, all having every day a large amount of stone flour to produce in various processing of stone places such as marble, grouan, this stone flour had not only occupied place but also contaminate environment, was refuse worthy of the name.The invention is intended to this stone flour is developed and utilized, make stone flour derive from building materials, reduce in building materials.
Summary of the invention:
The objective of the invention is, a kind of autoclaved and aerated stone powder building blocks of producing with stone flour is provided, the making method of this autoclaved and aerated stone powder building blocks is provided simultaneously.Its technical solution comprises:
A kind of autoclaved and aerated stone powder building blocks that adds is characterized in that with the stone flour being main raw material, and the weight proportion of its products material is as follows: stone flour 65-68%, calcium lime powder 25-29%, slag powders 5-7%, aluminium powder 0.5%, waste gypsum powder 0.5%.Here the cutting processing tankage powder that said stone flour is marble or grouan.
A kind of production method of aforementioned autoclaved and aerated stone powder building blocks is characterized in that: the weight proportion by products material is got material, and wherein stone flour adopts stone flour mud, is converted into the 65-68% that dry powder accounts for gross weight, finishes by following steps then:
(1) stone flour mud is crossed be sieved into material-compound tank and stir, recording stone flour slurry proportion is 1.62;
(2) calcium lime powder and slag powders, aluminium powder, the waste gypsum powder with digestion condition 〉=50 ℃ effective calcium 〉=50% drops in the material-compound tank simultaneously, goes into the mould cast molding after stirring evenly;
(3) keep at normal temperatures cutting into building block after 3 hours with definite shape and specification;
(4) autoclave is gone in building block, at 195 ℃ of temperature, pressure 13kg/cm
2Condition under thermostatic curing after 7 hours, unload and extrude still and be finished product.
The autoclaved and aerated stone powder building blocks that adopts such scheme to produce in September, 2006, detects its ultimate compression strength 3.0MPa, volume density 513kg/cm through building materials quality supervision and inspection station, Beijing
3, drying shrinkage value (standard law) 0.36mm/m, thermal conductivity (dry state) 0.13W/ (mk), freezes back intensity 2.4Mpa at the mass loss 2.4% of frost resistance.Every index all meets the index request of A2.5B05 grade salable product among the GB/T 11968-1997 " autoclave aerated concrete building block ".Meet the requirement of GB6566-2001 " the radioactive material nucleic is limited the quantity of " simultaneously, belong to sharp useless environmental protection and energy saving product.
Compared with prior art, advantage of the present invention mainly is:
(1) with the tankage utilization of waste material of various processing of stone, turns waste into wealth, both helped environment protection, can increase the economic benefit of stone material value-added content of product and building materials enterprise again.
(2) produce autoclaved aerated building block with stone flour, family has increased the newcomer for the available coagulation earth building blocks, and has more strong point than concrete segment, it is light weight, insulation, heat insulation, sound insulation, fire-retardant, antidetonation not only, but also has the advantages that can saw, can dig, can cut a hole, can follow closely as timber.This product safeguards that wall is unique materials for wall that just can reach national three phase building energy-saving standards with single-material outside doing.Especially compare with traditional solid clay brick, have more remarkable social benefit and economic benefit.
(3) directly use stone flour mud, not only water saving but also waste water carried out processing and utilizing is to achieve many things at one stroke.Because all needing with adding water during the stone material cutting is the knife saw cooling, therefore thereby make the stone flour foam become muddy, directly use the mud not only can water saving, the while be also carried out processing and utilizing with processing of stone waste water, wherein unnecessary mud water seepage can be in row utilization again when material-compound tank adds auxiliary material.Therefore adopt present method not have wastewater and waste materials substantially, except the gas that is evaporated, all dry-matteies all are bonded in the building block.
(4) as a kind of building material, its raw material sources is extensive, and is cheap, and formula for a product is scientific and reasonable, and production technology is simple relatively, and general building materials enterprise all can investment and production, therefore helps applying.
