Description

Powder ash air-entrained concrete building block and preparation method thereof

Technical field

The present invention relates to a kind of manufacture technology field of autoclave aerated concrete building block, especially refer to a kind of aerated coal ash concrete building block and preparation method thereof.

Background technology

Existing a kind of application number discloses a kind of autoclave aerated concrete building block and preparation method thereof for the Chinese invention patent that the CN200910304521.5 name is called " a kind of phosphorous slag autoclave aerated concrete building block and preparation method thereof ", and it is to add water phosphorus slag, silica sand, unslaked lime, cement, gypsum and aluminium powder to be prepared from.Compared with prior art, this invention is produced autoclave aerated concrete building block with producing the waste residue that phosphorus produced as the main raw that siliceous composition is provided, and is incubated, and can produce the autoclave aerated concrete building block of different stage according to demands of different.When making full use of the phosphorus slag waste, can also reach or slightly surpass the performance of traditional similar building block, when reducing production costs, reached the purpose of refuse reclamation.But its shortcoming is that the prescription kind is many, and it is relatively poor that the building block weight of production reaches soundproof effect more greatly.Also have a kind of application number to disclose a kind of concrete segment and production technique thereof for the Chinese invention patent that the CN200810020764.1 name is called " autoclave aerated concrete building block and production technique thereof "; It discloses a kind of mine tailing, the autoclave aerated concrete building block that improves the quality and production technique thereof of making full use of; The material prescription of this product is cement 180-220 kilogram, lime 280-330 kilogram; 2400 kilograms of mine tailings; Gypsum 15-150 kilogram, aluminium powder 0.00018-0.0002 kilogram, the operation steps of this production technique is: batching, stirring, injection molding, precuring; Upset, the demoulding; Rip cutting, crosscut; Go into still, steam-cured; The finished product warehouse-in; The advantage of this invention is: through prescription and corresponding a whole set of technology, the handling problem that has successfully solved glassy product waste material-mine tailing is turned waste into wealth; Because make full use of the characteristic of mine tailing, so compare with existing product, hardness is strong, promptly silicon content is higher by 40% than existing product; Mine tailing order number is very little, and ball milling or churning time are short, therefore can practice thrift 5 yuan of the electricity charge for every cubic metre.But there is above-mentioned shortcoming equally in it: i.e. it is relatively poor that building block weight reaches soundproof effect more greatly.So above-mentioned prescription and working method thereof all await improving.

Summary of the invention
