Advantage of AAC block
AAC block | Detail Description |
| 500-700kg/m3. Only the equivalent of clay brick 1/4-1/5 and
ordinary |
| The light brick has light capacity, good overall performance and
small |
| The compressive strength of light brick increases slightly at a
temperature |
| The inner structure of light brick is the same as bread which
distributes |
Quick Detail:
In the domestic development requirements of energy conservation and
environmental protection, we have upgraded, innovation and
development of aerated concrete production line equipment series
based on the initiation and absorption of German advanced
technology and design concepts. So far, we have provided a wide
variety of AAC equipment production line in different equipment
configuration and production capacity of domestic and foreign
customers. At the same time provide a variety of services for
customers, such as the upgrading of equipment, production capacity
expansion, raw material analysis, process design and layout,
project management etc..
Raw Material:Sand,Lime,Cement,Gypsum, Aluminum powder,Water
Power:380~450kw,220V,380V
Inspection and adjustment
a) Inspection:
i. After the mould frame and the side plate are put together, the
clamping arm should be able to turn freely without jamming.
ii. After the side plate is clamped tight and the mould is turned
over ninety degrees, there should be no leakage from the sealing
strips.
b) Adjustment
i. If there is too big a gap between the clamping arm and the side
plate or serious jamming occurs when the clamping arm turns, adjust
the distance between the clamping arm and the mould frame.
ii. If there is leakage from the sealing strips, adjust the pinch
roller on the clamping arm.
We can supply different equipment configuration for following AAC
production lines:
- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 50,000m3
- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 100,000m3
- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 150,000m3
- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 200,000m3
- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 250,000m3
- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 300,000m3

I Production Technique
1. Product Principle
1) Technology Orientation
Production and application of aerated concrete has a history more
than 40 years in China. Viewing from technology point, high quality
products can use 3mm special sand slurry technology to meet the
construction requests and 50% energy saving goals. (When mortar
joint is less than 3mm, take thermal conductivity coefficient of
wall as 1; when mortar joint is more than 3mm, take thermal
conductivity coefficient of wall as 1.5). Based on the history of
the aerated concrete development, only high quality products can
bring a prosperous market. Thus, the technology orientation of this
scheme is high-class products according to China Standard
GB11968-2006.
2) Production Capacity
The product is aerated concrete block and the output is 150,000m3
per year. The first phase can be equipped according to 100,000m3
per year. There is a reservation of plate in consideration of
user's need.
3) Product Specification
Products conform to requirement of 04~07 grade blocks stated in
GB11968-2006.
General Specifications of Aerated Concrete Blocks
Working Principle:
Technical Parameter:
The formulation of aerated concrete of 600kg/m3 absolute dry volume
weight is:
Sand : Quick Lime : Cement : Gypsum = 68 : 20 : 10 : 2
Aluminum accounts for 0.074% of the total volume of dry materials;
Ratio of water to material: 0.6~0.65.
Application Range:
Autoclaved Aerated Concrete AAC Production Line AAC Plant used for
products of AAC.
Operation Instruction:
One-shift production may be put into practice when piecework system
is carried out in the enterprise, but working hours must be
prolonged and workers of the shift must be increased, and also
labor protection should be done well. If four autoclaves are
arranged in Phase One, fixed persons are organized in one shift.
AAC is a kind of light cellular silicate products. Main material
based on Silicon materials ( sand, fly ash,gangue contains
silicon)and Calcium(cement and lime),mix with foaming agent
(Aluminium powder), after batching, mixing,
pouring,pre-curing,cutting,stream(autocaled),and other process
,finally, get this light weight concrete products..
Fly-Ash: fly ash is waste from Thermal plant.Fly ash is rich in silica and
aluminum oxide ,so it is good raw material to make aac block. Fly
ash is also divided into two kinds--wet fly ash, dry fly ash.The
dealing way will vary as per the fly ash condition
Sand: Except fly ash,Sand can be the main material too.The requests is
that the Silica content is above 69% .Sea sand can not be used as
aac raw material.
Lime: Active powered lime is a requirement for giving the real aeration
to the product. In phase 1 we can aim to buy the active lime
directly. In phase -2 we can think of having backward integration
and making a lime powering unit at site to have a more competitive
advantage, We can also think of a lime burning klin inside the
factory premises. The project financials however have not
considered the costs of powering unit, and the lime kiln in this
project. Different qualities of lime are available, and depending
on the raw materials, the mix design can be chosen to get the
optimal quality of production.
OPC cement. This Project aims to utilize OPC cement as main binder material.
It will give faster strength to the bricks, besides giving improved
consistent quality. It also ensures a better cost effectiveness for
the same. Using OPC will be a standardized practice. The other
prime advantages of using OPC (compared to other binders) is it's
easy availability locally through nationwide Retail Network of
Cement Companies.
Gypsum: This too is an industrial waste. This is available as an
industrial byproduct of Fertilizer Plant. Gypsum is responsible to
give long term strength to the Blocks.
Aluminum Power. Finely ground Aluminum power is used in very limited quantity (
less than 0.5%), so that it reacts with active lime, and silica in
base material to make the aeration.
