I.low construction cost

Autoclaved aerated concrete block dry density of 300-700kg / m3, as the red brick (1500kg / m3) 1/3, 1/4 concrete. Obviously can significantly reduce the weight of the building, greatly reducing the cost of building the foundation and construction of the structure, according to the Shanghai Institute of Architectural Design calculations, in the top frame structure of the building, the use of autoclaved aerated concrete block wall filled with doing than using clay bricks can reduce the weight of buildings by 25%, saving 18% of concrete, steel 15%, reduce the project cost by about 20%.

II.the use of low cost

Due to better performance than conventional insulation wall materials, can greatly reduce the use of air conditioning and other building heating and cooling equipment energy usage charges, long-term energy savings.

III.construction speed, high efficiency

Autoclaved aerated concrete block Dimensions precise size error within ± 2.0mm, can effectively guarantee the smooth masonry walls. In addition, the use of dry construction technology, masonry greatly accelerate the speed, ease of processing and because the product, so that re-decoration and residential water pipeline laying more convenient, can significantly speed up the construction progress, shorten the construction period.

IV.non-radiological hazards 

Autoclaved aerated concrete block raw material is natural silica sand in the production, transportation and use of the process not produce any pollution, it is an ideal green building materials, people and the environment are not real and potential hazards.

V.insulation, excellent insulation properties

Jiangshan autoclaved aerated concrete block conventional thermal conductivity <0.12w / mk. f stay warm effect is brick six times, 12 times that of ordinary concrete, insulation performance 80mm thickness of light sand aerated concrete block is equivalent to 480mm of brick wall. 200mm thickness usually lightweight autoclaved aerated concrete blocks (B05) for the exterior walls, the insulation material can not increase aid to meet the thermal insulation requirements.

VI.strong impermeability

Because of autoclaved aerated concrete block inside the closed pores are independent uniform pore diameter of about 1 -2mm, because two pen effectively prevent moisture diffusion within the block. When ordinary outdoor painting, wall impermeability to 85% higher than the brick wall, and therefore more suitable for wet areas as wall materials.

VII.fire performance outstanding

Autoclaved aerated concrete block raw materials and products do not burn. Test and practice have proved wonderful aerated autoclaved lightweight concrete is an ideal port of fireproof material, 10cm thick the wall of fire resistance up to four hours, it is widely used as a firewall material.

VIII.good noise performance

Depending on the the wall thickness and surface treatment methods, lightweight autoclaved aerated concrete wall may sound about 38-68 decibels. It is also a good sound-absorbing materials, insulation to meet a number of high-grade construction, special construction and building strong noise requirements.

IX.the intensity level providers

Because of the light, the quality of autoclaved aerated concrete block size, accuracy and cut six sides, are available special masonry mortar thin masonry, mortar joint thickness of 3? 5mm, the strength utilization factor greatly improved. Masonry strength can reach 80% intensity block itself (much larger than the red brick of 30%), strength index significantly higher than other wall materials.

X.seismic rating high

Building structure using the same country aerated concrete block, brick comparable to improve seismic level.

Ash of aerated

Sand aerated

Raw materials and costs

Fly ash, cement, of lime, aluminum pastes, raw material costs low

Sand, cement, of lime, aluminum powder, the raw material cost is relatively high

Production Process

Simple, to the artificial main

Computer control of process parameters, increasing milling equipment, high degree of process automation

The basic properties of materials

Pore structure difference, even vent more poor impermeability, water absorption.

Internal holes are independent uniform closing hole diameter of about 1-2mm, it can effectively prevent water diffusion within the block. Small water absorption, while "aerated concrete block" unique construction technology, can effectively prevent the slab and masonry mortar joint seepage, when ordinary outdoor painting, the wall higher than the brick the wall impermeability 85%.

Contractility

Drying shrinkage reached 0.6-0.8mm / m, the wall is easy to crack.

Rapid drying method measuring ≤0.5mm / m In fact, in its natural state shrinkage smaller, the general state of nature, only 0.1 mm / m or so, the wall is not easy to crack.

Construction Technology

Generally the wet, can also be dry

Dry construction, more efficient

Thermal conductivity

Thermal conductivity ≤16 [W / (m.k)]

Thermal conductivity special ≤0.12 [W / (m.k)]

Sound insulation

Multi-ash aerated blocks pore structure can absorb 30 to 50 db sound waves

Sand filling block multi-pore structure can absorb 38 to 68 db sound waves

Product Form

Blocks, relatively simple

There are a variety of forms blocks, plates, profiles and other

Durability
