Description
Technical field
The present invention relates to a kind of modified form lightweight aerated concrete building block.
Background technology
Air-entrained concrete building block is a kind of light porous, insulation, fire protecting performance is good, can follow closely, can saw, can dig and have
There are the New Building Materials of certain shock resistance.Early in the '30s initial stages, China begins to produce this product, and makes extensively
With.For example：In Shanghai International Hotel, Shanghai mansion, Foochow building, People's Bank of China's building contour level building.It is a kind of excellent
Good New Building Materials, and there is environmental protection.But the formula of current miscellaneous air-entrained concrete building block
It is not quite similar, causes in performance also gap.
The content of the invention
It is an object of the invention to provide a kind of modified form lightweight aerated concrete building block with superior physical property.
Technical problem solved by the invention can be realized using following technical scheme：
A kind of modified form lightweight aerated concrete building block, it is characterised in that count by weight, the air-entrained concrete building block

1st, it is lightweight
The general weight of air-entrained concrete building block of the present invention is 500-700 kilograms per cubic meter, is only equivalent to clay brick and ash
The 1/4-1/3 of sanded brick, the 1/5 of normal concrete, it is lighter one kind in air-entrained concrete building block concrete, it is adaptable to which high level is built
The filling wall and the load bearing wall of low-rise building built.Using this material, the deadweight of whole building can be made than common brick mix structure
The deadweight reduction by more than 40% of building.Because structural weight per square meter mitigates, destructive power of the earthquake is small, so greatly improving the antidetonation of building
Ability.And the inside of air-entrained concrete building block is arranged at intervals with the through hole at some penetrating length two ends, through hole along its length
Filled with heat-preservation cotton, further mitigate weight.
2nd, thermal and insulating performance is good
The thermal conductivity factor of air entrained concrete is only the 1/4-1/5 of clay brick and Dinas brickes, is that the 1/6 of normal concrete is left
It is right.It facts have proved：The heat insulation effect of the aerated concrete wall of 20 cm thicks is equivalent to the clay brick wall of 49 cm thicks
Heat insulation effect, heat-proof quality is also significantly better than 24 centimetres of brick wall bodies.The thickness of wall is thus thinned significantly, is accordingly expanded
Effective usable floor area of building, has saved construction material thickness, has improved efficiency of construction, reduced construction costs, alleviated
Building is conducted oneself with dignity.
3rd, high fire resistance
Because air-entrained concrete building block thermal conductivity factor is low, thermophoresis is slow, is highly resistant to fire, and it can be protected to tie

Intensity was not damaged in the past, and belonged to inorganic incombustible in itself, and toxic gas will not be produced at high temperature.
4th, sound insulating and absorbing performance is good
The sound insulation not having with common buildings material and sound absorption qualities.
5th, water permeability resistance can be good
It is particularly suitable for the more area of typhoon, heavy rain and makees materials for wall.
6th, it is "dead"
Air-entrained concrete building block employs "dead" raw material.Therefore, product complies fully with state health standards, category
In environment-friendly and green building materials.
7th, shock resistance is good
Because aerated concrete density is light, overall performance is good, and inertia force is small during earthquake, so with certain antidetonation energy
Power.
8th, durability is strong
Through experiment, air-entrained concrete building block compression strength is more than 25,000 grams/cm, equivalent to No. 125 clay bricks and
The compression strength of Dinas brickes.
9th, machinability is good
Air entrained concrete has good processing characteristics.Can saw, can dig, can follow closely, energy milling, can bore.And it can manufacture
In journey plus reinforcing bar, very big convenience and flexibility are brought to construction.
10th, shrinkage value is small
The present invention air-entrained concrete building block as a result of high-quality silt as siliceous material, its shrinkage value is only
0.3-0.5MM/M, the small quality material of shrinkage value, it is ensured that wall will not ftracture.
