Autoclaved Aerated Concrete Block Making Machine Production Line with Curing Room

1. Product introduction

AAC is a new type environment friendly and lightweight building material which is made of fly ash, lime, cement, gypsum and aluminium powder. Autoclaved aerated concrete block is one kind of aerated concrete products, it can take different processes according to the raw material category and quality.The autoclaved aerated concrete block with porous structure is formed through high temperature, high pressure and steaming, it also has advantages of extremely lightweight, fire proof, sound insulation, anti-shock, environmental-friendly, durability, economies. As a new building material,aac is emphatically promoted by the world.

5. Main characteristics of Aerated Autoclaved Concrete  block:

Lightweight
*Porosity achieve 70% to 85%, volume density is generally 500 ~ 900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building.
Fireproof
*Porosity achieve 70% to 85%, volume density is generally 500 ~ 900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building.
Sound insulation
* Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 db.
Anti-seismic
*The same building structure,Earthquake intensity is higher than ordinary brick.
Environmental-friendly
*Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
Durability
*Material strength is stability,in the specimens tested after one year of atmospheric exposure;the intensity increased by 25%,and remained stable after ten years.
Economies
*An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
  

6. AAC block raw materuial

Fly-Ash
A lot has been said about this raw material in this Project Profile itself. But this Raw material is freely available in Thermal Power plants. There are no taxes on this item whatsoever. Transportation charges are only to be attended by the entrepreneur.    
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.
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
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.

9. The necessary preparation of establish a AAC block plant

1.  Land of  4 Acres is Required  
2.  Workshop area -approximately 30000 Sq Mt or 30000 sft  
3.  Total Plant area( construction area ) = 4500 Sq Mt or 45000 sft  
4.  Power connection  needed - 500 KVA  
5.  Ideal manpower requirement is 40 nos. (Skilled - 10, semi skilled-10 and unskilled 20)  
6.  Skill division 40 workers = Main plant 2 nos of 10 hour shifts 15 people each + Boiler & Autoclave section 3 people in 3 shifts of 8 hours  
7.  Water requirement approximately 225 Tons per Day.
8.  Fly Ash requirement approximately 225 Tons per day
9.  The above power and plant calculations are based on Fly ash based AAC without Lime Crushing Unit and Ball mill for sand. If the process so require, we may add them at a later stage. But surely we give provisions for them at site right from installation stage  
10.  300 working days is considered in a year through 333 days a year is possible.
11  Fly to be provided free of cost by power plants. Only transportation to be arraigned by Project. Average distance of 250 KM  
12.  Carbon Credit is estimates are for reference purpose. The Project owner must handle his part of CDM project to get Carbon credits, through independent consultants. Please check the form of CDM after 2012  
13.  AAC Blocks of all sizes will be manufactured according to the market requirement, though mainly stipulated sizes as per the BIS standards.
