Abstract
The invention discloses an autoclaved aerated concrete block. The autoclaved aerated concrete block is prepared from the following raw materials in parts by weight: 40-50 parts of coal ash, 15-25 parts of silicon sand, 8-15 parts of mineral powder, 3-6 parts of slag, 3-6 parts of cement, 8-12 parts of lime and 0.5-1.2 parts of aluminum powder. The autoclaved aerated concrete block has the beneficial effects that the usage amount of the coal ash is reduced, and meanwhile, various technical indexes can all reach domestic and overseas advanced levels, namely the desiccated bulk density is 614kg/m<3>, the heat conductivity coefficient is 0.153w/(m.k), and the compressive strength is 3.6-5.0Mpa.
Description
Technical field
The present invention relates to a kind of concrete segment, particularly relate to a kind of autoclave aerated concrete building block.
Background technology
In prior art, employing be the proportioning mode of flyash, cement, lime, aluminium powder, flyash accounting is 82%, cement accounting is 5.49%, lime accounting is 12.6%, aluminium powder accounting is 0.11%.The indices of the concrete segment that proportioning is produced thus does not all reach optimum regime, the output of adding present flyash die-offs, cannot meet the consumption of producing 18 ten thousand steres per year, therefore change technical recipe, find new starting material and act on behalf of flyash, debugging out optimised process proportioning has become the problem that we need to break through.
Summary of the invention
The invention provides a kind of concrete segment that adopts new proportioning, solve the problem of above-mentioned existence.
The present invention realizes by following technical scheme:
An autoclave aerated concrete building block, is characterized in that, comprise weight part be the flyash of 40-50 part, the breeze of the silicon sand of 15-25 part, 8-15 part, the cement of the slag of 3-6 part, 3-6 part, the aluminium powder of the lime of 8-12 part, 0.5-1.2 part.
Above-mentioned a kind of autoclave aerated concrete building block, is characterized in that, comprises that weight part is the flyash of 47.33 parts, the silicon sand of 22.72 parts, the breeze of 11.36 parts, the slag of 4.54 parts, the cement of 4.24 parts, the lime of 9.72 parts, the aluminium powder of 0.85 part.
Above-mentioned a kind of autoclave aerated concrete building block, is characterized in that, described slag replaces with waste product fragment.
A kind of autoclave aerated concrete building block of the above, is characterized in that, the A level slag CaO+MgO in described breeze accounts for the more than at least 65% of whole breeze.
Beneficial effect of the present invention is: the steam pressure concrete segment of production has kept all technical all can reach domestic and international advanced level when having reduced flyash usage quantity, is respectively: dry volume density 614kg/m
3, the normal 0.153w/ of thermal conductivity (m.k), ultimate compression strength 3.6-5.0Mpa.
Embodiment
Below in conjunction with embodiment, the present invention will be further described.
An autoclave aerated concrete building block, comprise weight part be the flyash of 40-50 part, the breeze of the silicon sand of 15-25 part, 8-15 part, the cement of the slag of 3-6 part, 3-6 part, the aluminium powder of the lime of 8-12 part, 0.5-1.2 part.
In one of them preferred implementation of the present invention, a kind of autoclave aerated concrete building block comprises that weight part is the flyash of 47.33 parts, the silicon sand of 22.72 parts, the breeze of 11.36 parts, the slag of 4.54 parts, the cement of 4.24 parts, the lime of 9.72 parts, the aluminium powder of 0.85 part.
In said ratio, slag can replace with waste product fragment.A level slag CaO+MgO in breeze accounts for the more than at least 65% of whole breeze.
Silicon sand, breeze are mining site waste, and fragment is that waste product fragmentation forms, and slag is boiler emission solid waste, due to by a large amount of utilization of waste material, has not only recycled resource, have also reached the effect of environmental protection simultaneously.
The breeze of producing autoclave aerated concrete building block is through shrend granulated blast furnace breeze, A level slag CaO+MgO in breeze accounts for the more than at least 65% of whole breeze, SiO2 and Al2O3 in the contained glassiness composition of this breeze have activity, storing can in a large amount of chemistry, thereby can improve the stability of cast, the sclerosis of base substrate is played to certain promoter action.Under autoclaved condition, the silicate mineral in breeze can generate low buck compound with SiO2 effect simultaneously, thereby improves the intensity of autoclave aerated concrete building block.
Beneficial effect of the present invention is: the steam pressure concrete segment of production has kept all technical all can reach domestic and international advanced level when having reduced flyash usage quantity, is respectively: dry volume density 614kg/m
3, the normal 0.153w/ of thermal conductivity (m.k), ultimate compression strength 3.6-5.0Mpa.
More than show and described ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what in above-described embodiment and specification sheets, describe is principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain that the present invention requires is defined by appending claims and equivalent thereof.
