Advantage of AAC block

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


Description:

Project Proposal of AAC Production Line AAC Plant
Annual out put 50,000-300,000m3
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.
