Description
Technical field
The present invention relates to a kind of modified form air-entrained 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.Such as：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 have the advantages that environmentally friendly.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 air-entrained 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 air-entrained concrete building block, it is characterised in that count in parts by weight, the air-entrained concrete building block former material
Material includes following components：
Water 250-350 parts；
Aluminium powder 3-8 parts；
Gypsum 60-80 parts；
Lime 80-90 parts；
Tailings 150-200 parts；
Silt 150-200 parts；
Flyash 60-80 parts；
Cement 70-90 parts；
Additive 3-8 parts；
Soda ash 5-20 parts；
Wherein more than the dioxide-containing silica 90wt% of tailings, more than the dioxide-containing silica 80wt% of silt.
In a preferred embodiment of the invention, count in parts by weight, the air-entrained concrete building block raw material include with
Lower component：
300 parts of water；
5 parts of aluminium powder；
70 parts of gypsum；
85 parts of lime；
170 parts of tailings；
180 parts of silt；
70 parts of flyash；
80 parts of cement；
5 parts of additive；
10 parts of soda ash；
Wherein more than the dioxide-containing silica 90wt% of tailings, more than the dioxide-containing silica 80wt% of silt.
The beneficial effects of the present invention are：
1st, it is in light weight
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 one kind lighter in air-entrained concrete building block concrete, is built suitable for high level
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 of building reduces by more than 40%.Because structural weight per square meter mitigates, destructive power of the earthquake is small, so greatly improving the antidetonation of building
Ability.
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 are 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 can protect its knot
Structure is not by influence of fire.Its refractoriness of air-entrained concrete building block is one-level refractory material, when temperature is at 700 DEG C more than 700 DEG C
Intensity was not damaged in the past, and belonged to inorganic incombustible in itself, will not produce toxic gas 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
Make materials for wall in the area more particularly suitable for typhoon, heavy rain.
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
Add reinforcing bar in journey, very big convenience and flexibility are brought to construction.
10th, shrinkage value is small
The present invention air-entrained concrete building block be only as siliceous material, its shrinkage value as a result of high-quality silt
0.3-0.5MM/M, the small quality material of shrinkage value, it is ensured that wall will not ftracture.
