Lightweight green Panels
Autoclaved Light weight Aerated Concrete Panels with cement, lime, silica sand as raw materials, adapting two-way and welded steel reinforcement mesh (Reinforcing Bar) Processed by special anti-rust liquid, produced in a high temperature, high pressure and steam curing, it's a kind of porous silicate plate of high performance, and has many incomparable performances of good fire-resistance, fire prevention, sound insulation, heat insulation, thermal insulation etc. It can be categorized into external wall panels, partition panels (internal panels), roof panels, floor panels according to usage.
It also can be used for outsourcing fire panel of steel beam and columns, and the veneer and the external wall insulation panel. AAC panel is processed according to the definitized sizes by actual field measurement. As a prefabricated product, it's of high precision, sawable and drillable. Used in dry operation, it is convenient to install in a simple process, greatly shortening the construction period, and improving the efficiency and quality of construction. The reinforcement (reinforcing bar) is calculated and determined according to the work load, the specifications of the panel, and the Applications Handbook of AAC panel.

Product Performance of AAC Panel
i) Low-Carbon environmental protection
KIB actively promotes green architecture and advocates low-carbon life. Because of its low density, KIB products not only features low raw material consumption, but also reduces carbon emissions during transportation and installation process.. The high-performance, low material consumption, good durability and other features of KIB products meet the controlling requirements of the Green Building Evaluation Standard. AAC panels are inorganic materials. There is no problem of aging or weathering. The durability is the
same as concrete, so they can serve as long as the building lasts. The adhesives used are also inorganic materials like cement, achieving a better overall compatibility and durability. It was first used in a project based in Shanghai more than 70 years ago and remains intact until now. It is simple, convenient and economical for daily maintenance during the process of using. AAC panels
can be recycled after the wall removal without environmental pollution.
ii) Thermal insulation
The inside of AAC panel is composed of many small holes, which are independent and in order. The porosity is nearly 80%. The small holes, filled with air, are not connected and the air inside stays static, so air becomes the major thermal conductivity medium. As the thermal conductivity of air is very low, about 0.026W / (m • K)，that ultimately makes the thermal conductivity of the material very low, thus satisfying the purpose of the insulation.
iii) Fire resistance
KIB raw materials and products themselves are inorganic non-combustible materials and have absolute incombustibility, so that they fundamentally do not have the fire safety hazards of most organic insulation materials. Therefore it's a kind of safer, more economical and reliable energy conservation and heat insulation system. As the experiments show, there is no strength loss for AAC panel even in a temperature as high as 700°C. A 15cm-thick wall can resist fire for as long as 4 hours. It is an ideal Class A fireproof construction material. When a fire accident occurs, AAC panel will not release any smoke or toxic gas. Because of the small thermal conductivity, heat is migrated slowly, and even the thinner AAC insulation panel can effectively resist the fire, prevent the spread of fire, and protect the structure from the impact of the fire.
iv) Light weight & high strength
High porosity of AAC panels can reduce the bulk density of materials. The absolute dry density of different grade products are 400-600 kg/m3, only 1/5 that of concrete. It can effectively lighten the weight of the building, reduce labor intensity during construction, and save costs in the base and structure of the houses. Although AAC panel itself is very light, the structure of the material in each direction can balance the load-bearing, and KIB adopts exact hexahedral cutting size and appropriative thin layer of mortar masonry, so as to highly improve the intensity utilization coefficient. AAC panel can be used with reinforcing bar according to the design to meet a variety of load bearing requirements. Reinforcing bar in the panels perform stabilized, toughening and impact resistance functions. Before producing panels, it is necessary to rationally design the plate reinforcement (including: structure and size of reinforcing bar) according to the load requirements of the specific projects, making bearing capacity, shear resist requirements. After production, the panels also need to be tested through sampling to review whether the structure performance meets the load requirements, stiffness, and deflection indicators to meet the requirements.
v) Economical cost
Project period shortened by 2/3 AAC panel is lightweight and easy-processed, which may ease labor intensity. Internal and external walls can be constructed at the same time, so construction speed is faster and labor costs are reduced. AAC panel is masoned and coated by dry powder mortar. Heat insulation time is reduced, project time is shortened by about 2/3, so that capital turnover is expedited.
vi) Low basic investment
AAC panel is lightweight and high strength so as to reduce a series of investments for maintaining structure weight. Reducing floor loading and weight can not only decrease the base cost, but also reduce the quantity of steel bars or size of concrete beams, columns and floor panels, so the whole project cost is lowered. KIB AAC wall panel are used as wall materials that highly increase the usable area of the buildings and reduce energy consumption. AAC internal panels are the thinnest among those with the same capacity in sound insulation and fire protection. There is no need to use structural post, beam and other auxiliary components so that wall loading is decreased and building cost is reduced as well.
vii) Good anti-cracking ability
Shrinkage rate of KiB AAC products is much smaller than national standard 0.5mm/m and other wall materials. The smaller the dry shrinkage rate , the better the anti-cracking ability. Moreover, dry construction avoids wall cracking because of dry shrinkage. AAC panel is masoned by special mortar whose thickness is only 3mm, so cracking possibility of the gap is greatly lowered. Wall is elastically connected, which is beneficial to avoid cracking even if the base subsides. AAC panel can be used directly in internal wall of concrete structures and steel structures, such as in hotels, schools, offices, market places and houses etc. The internal walls such as household walls, separating walls, partition walls in bathrooms and kitchens etc. conform to hang various things such as air conditioning, water heater, radiator, hanging cases etc. Compared with traditional internal wall partition materials, AAC internal panels have obvious advantages in various technical performances: lightweight, high strength, thermal insulation, fire resistance, sound insulation, seepage prevention, frost resistance, durability, anti-seismic, high softening coefficient, no radiation, good creativity, scientific installing method, convenient and quick
construction.
