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.
2nd, wall thermal insulating heat-proof quality 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.Insulation filler is added in special mortar, further increases thermal and insulating performance.
3rd, the high fire resistance of wall
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
Structure is not by influence of fire.Its refractoriness of air-entrained concrete building block is one-level refractory material more than 700 DEG C, when temperature is at 700 DEG C
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, wall sound insulating and absorbing performance is good
The sound insulation not having with common buildings material and sound absorption qualities.
5th, wall water permeability resistance can be good
It is particularly suitable for the more area of typhoon, heavy rain and makees materials for wall.
6th, wall 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, wall 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, wall 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, wall 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, anticracking and anti-wall shrink
Special mortar can combine closely building block, and anticracking and anti-wall shrink.
11st, 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.
