Materials Used
Manufacturing
Process of AAC Blocks
1. Cement
The suitable Cement for the manufacture of AAC blocks is OPC grade 53 that sets and hardens and can bind other materials together.
2. Limestone
Limestone is obtained either by crushing to fine powder at the AAC factory or by directly purchasing it in powder form from a merchant.
3. Fly Ash
Fly ash is a waste industrial product used for the reduction of construction cost. The density of fly ash ranges from 400-1800 kg/m3. It provides thermal insulation, fire resistance, and sound absorption. The type of fly ash used is Class C which contains 20% lime (CaO) and loss of ignition not be more than 6%.
4. Aluminum Powder
Aluminum is an expansion agent. When the raw material reacts with aluminum powder, the air bubble introduced due to the reaction between calcium hydroxide, aluminum and water, and hydrogen gas is released.

AAC blocks: Where are they used?
AAC blocks are widely used in the construction of apartments and other types of residential properties, industrial and commercial buildings, such as hotels, offices, hospitals and schools. Owing to their excellent heat insulation capacity, AAC bricks find application in interior and exterior construction. They are ideal for high-rise structures.

Manufacturing Process of AAC Blocks
Step 1: Prepare the Raw Materials
The process of preparing raw materials involves combining fly ash with water to create a slurry that can then be combined in the proper ratio with other raw materials including cement, gypsum, and aluminium powder.
Step 2: Dosing and blending
This procedure is crucial since it affects how well the final product turns out. The needed final product determines the ratio in which the raw components are to be added.
A container is pumped with fly ash. Pumping is halted once the desired weight has been pumped in.
- Similar to that, conveyors are used to pour individual containers with gypsum, cement, and lime powder.
- The control mechanism releases all ingredients into the mixing drum once the necessary quantity of each ingredients has been put into each of their respective containers.
- The slurry is prepared to be put into moulds using the dosing equipment after being stirred for a predetermined amount of time.
Step 3: Casting, Rising, and Curing
The size of the moulds could vary depending on the amount of mix that is needed.
- To prevent the green cakes from sticking to moulds, a thin layer of oil is applied to them before casting.
Hydrogen gas is produced when aluminium interacts with calcium hydroxide and water. This causes small cells to develop, which causes the slurry mix to expand.
- The volume of this extension might increase by three times. The bubbles measure from 2 to 5 mm. As a result, this explains why the AAC block is lightweight and insulating.
The green cake is allowed to settle and cure after the rising process.
- Rising and pre-curing typically take between 60 and 240 minutes.
Step 4: Cutting and Demoulding
It is demoulded and cut to specifications after it has reached a cutting strength.
AAC blocks are typically sold in sizes of 600 x 200 x 100, 600 x 200 x 150, and 600 x 200 x 200.
