How Does Autoclave Work In AAC Blocks?

The autoclave for AAC blocks has a simple working principle. For the production of aerated autoclaved concrete, steam curing is required. The autoclave supplies saturated steam and surrounds the concrete body until the calcium oxide and calcium silicate start reacting.

After a particular time in the saturated steam at high temperature, the fly ash’s calcium oxide and silica quicklime’s calcium silicate react. It results in hydrated calcium aluminium gel that, in return, produces aerated autoclaved concrete blocks.

Note that you must set a certain pressure and temperature for an effective curing system. And you must know how long to cure for producing a high-quality AAC concrete block. Too long and too short curing may result in ineffective curing and produce low-quality aerated concrete.

If you are not experienced, we suggest contacting our engineers. As an after-sales service, they will help you analyze the perfect parameters for producing high-quality aerated cement blocks when installing our autoclave for AAC blocks.

What Is Autoclaved Aerated Concrete?

The AAC aerated autoclaved concrete is a precast building material that has lightweight, are fire and mould-resistant, and has excellent insulation properties. Generally, these autoclave blocks are used in the inner leaf of a cavity wall. However, due to their wide range of properties, you can construct a complete house with these autoclaved lightweight concretes,

It comprises of cement, lime, quartz sand, aluminium powder, and water. These reinforced autoclaved aerated concretes are manufactured with the help of autoclave for AAC blocks using high temperature saturated steam curing.

Most people think that the autoclaved aerated blocks and dense concrete are the same. But that’s not true. The aerated cement blocks and dense concrete differ in their properties; even their production method is different from each other.

Dense concrete is just a cement and water mixture with some percentage of PFA and coarse and fine aggregate. Its full strength comes from the cement hydration that usually takes months.

On the other hand, the AAC concrete for sale has a comparatively much lower density and is extremely light weighted. In comparison to dense concrete, the aerated cement concrete production process takes less time. When it comes out of the autoclave and gets cooled, it is ready to use – no need to wait for months.

What Is The Manufacturing Process Of Autoclaved Aerated Blocks?

Autoclaving AAC (Autoclaved Aerated Concrete) blocks involves placing the blocks in a chamber or autoclave, which is then pressurized with steam. The process typically includes the following steps:

  1. Loading: AAC blocks are stacked inside the autoclave, ensuring there is enough space for steam circulation around each block.
  2. Pressurization: The autoclave is sealed, and steam is introduced to raise the internal pressure. This pressure helps to cure the blocks and achieve the desired strength.
  3. Heating: The temperature inside the autoclave is raised to a specific level, usually around 190-200°C, and maintained for a set period.
  4. Curing: The combination of heat and pressure cures the blocks, leading to a chemical reaction within the material that gives it its final strength.
  5. Cooling: After the curing process is complete, the blocks are cooled down slowly inside the autoclave before being removed.

Autoclaving is a critical step in the production of AAC blocks as it helps ensure the blocks achieve the desired strength and other properties.

The AAC has a completely different manufacturing process. Unlike other concrete, it is produced using aggregates the size of sand particles. The AAC thermalite blocks manufacturing process includes the involvement of binding agents. The lime, calcined gypsum, quartz sand, water, and cement are the binding agents in this product. And it involves the addition of aluminium at rates between 0.05 – 0.08%

After the mixing, multiple chemical reactions occur, which is responsible for AAC’s high thermal insulation properties and its lightweight. After the reaction of calcium hydroxide and aluminium, the foaming process starts. As a result, the foaming process starts, and hydrogen gas starts producing in the form of bubbles.

When the autoclave for AAC blocks foaming process completes, the hydrogen gas exits and gets mixed with the air.

After foam removal, it softens, which are then cut into different shapes. When it’s perfectly sized, these materials are placed into an autoclave for the curing process.

During the curing process, calcium silicate hydrate forms due to the reaction between calcium hydroxide and quartz sand.

At the end of the autoclaving process, the high-strength aerated cement blocks with excellent insulation properties are ready for use.

What Is Autoclaved Aerated Concrete Used For?

The autoclaved lightweight concrete has extensive thermal insulating properties that can be used both for interior and exterior construction. In addition to its thermal insulating ability, it offers easy installation because it can be cut to size and routed in the same facility.

Since the autoclaved aerated cement blocks have very low density, it’s beneficial for huge buildings. Plus, the buildings constructed with AAC building blocks require less steel and cement without compromising the building’s standing strength.

As the number of joints decreases, more miniature mortars are required for laying aerated building blocks. In the same way, it reduces the rendering cost due to dimensional correctness. Although common cement mortars are useable, most buildings with AAC erection use thin-bed mortars with thickness 3mm – 3.2mm.

Besides cost-friendliness and strength, the autoclaved aerated cement blocks offer extreme thermal insulation. It makes these aerated thermal blocks highly beneficial for areas with extreme temperatures because you won’t need to use two different materials for construction and insulation. Why use two different materials when one can provide both advantages, right?

For long-lasting use, you can use a stucco or plaster compound to coat the aerated lightweight concrete blocks. It helps guard against other elements. Additionally, you can use brick or vinyl cover for extra benefits.
