How to making and get the good quality of AAC Light Concrete

The main concept to making the good quality of AAC light Concrete will be supported by 1. Machine 2. Operational to Man power and Lay out of flow process production 3. Additive Echivement from these will be - Good in runabilty of the machine - less down time will be impacted to high of efficiency - good in the additive and composition will be impact to the density of the products. -etc

How Strength the Products

The basis concepts to making the good quality of AAC Products i.e
1. Mechanical - How is the Equipments in term of , Quality, precision, works - Process
2. Chemical/ Additive , How is choising the better / best of raw material.
3. Skill of Man Power

HOW TO MAKING AAC CONCRETE

So many ideas just like " How to making AAC product in manufacturing "
Just simple THINK,
- Have the machine - not to high technology - simple machine
- Have the sources of material i,e Sand ( silica ) , Fly ash, or Bottom Ash, Quicklime,
cement and some ingredient i,e Anhydrate, Raising Agent.
- Have the Cooking - ( production people )
- Have the good recipe.
- Have the Market or Internal market
- Have the strategies - Location
                                - Infrastructur

Finally Just Do It : 2MOC
M = Market
M = Have mechanical
O = Operational
C = Chemical or additive

And got the bread as Aerated Autoclave Concrete

COOKING AAC ?

How to making AAC ?

To making AAC products is analogous how to baking bread , so we have to use
- Yeast , to making the bread to expand or fill with air
- Flour  , as same with sand powder or Fly ash , to mixing together to making the bread more test and
              uniformity
- Ingredients .

All the raw material have to mixed well and after that go to the mould and give the bread to expand and the finally go to the oven to making bread  .

Enviromental Benefits of Light Concrete - AAC ( Green Products )

Environmental benefits of Light Concrete - AAC

The use of AAC has a range of environmental benefits:

Insulation:

Most obviously, the insulation properties of aircrete will reduce the heating costs of buildings constructed with autoclaved aerated concrete, with consequent fuel savings over the lifetime of the building.

Materials:

Lime is one of the principal mix components and requires less energy to produce than Portland cement, which is fired at higher temperatures. Sand requires only milling before use, not heating, and PFA is a by-product from electricity generation. NB: lime may require less energy to manufacture compared with Portland cement but more CO2 is produced per tonne (cement approx. 800-900 kg CO2/tonne compared to lime at 1000 kg CO2 per tonne).

Carbonation:

Less obviously, the cellular structure of aircrete gives it a very high surface area. Over time, much of the material is likely to carbonate, largely offsetting the carbon dioxide produced in the manufacture of the lime and cement due to the calcining of limestone.

Procedure to Making Light Concrete ( Autoclave Aerated Concrete - AAC )

Procedures to Making Light Concrete ( equivalent to product like HEBEL / CITICON or other Light Concrete )

1. Weight all the raw material and put to mixer and add rising agent , do mixing while the raw

material put in the mixer 3-5 min max.

2. Open the outlet of the mixer and the slurry go thru to the molding, ussually the molding for

2-3 M3 of volume.

3. Rise the high of Moulding 50 - 60 % of total high moulding.

4. Sent to the Curing Room for cure the Slurry for 3-4 hours , to getting the completely reaction

between rising agent with lime hydrate to produces hydrogen gases and the slurry tobe

come green concrete and incresed 90-100 % higher.

5. Unloading green concrete from moulding and do the cutting size ( cutting machine ) as market

requirments.

6. Sent the green concrete to the Autoclave for the final reaction for 12-14 hours.

Temperature and Pressure will be controlled .

7. Finish product ready to distributed or sell.

NOTE : The k factor ( Strength N/mm2) and Density kg/M3 were depand on the

1. Compasition of Raw Material

- Cement and Sand

- Cement and Fly Ash or

- Cement , Fly Ash and sand

2. Viscosity of Slurry when in the Mixer.

3. Operational of Autoclave
