Autoclave AAC Plant Manufacturer

Technomart offers Autoclaved Aerated Concrete (AAC), also known as Autoclaved Cellular Concrete or Autoclaved Lightweight Concrete. AAC is a certified green building material widely used for walls, floors, and roofs, providing superior strength, insulation, and sustainability. Choose Technomart for high-quality AAC blocks that enhance energy efficiency and durability in construction projects.

AAC, or autoclaved aerated concrete Plant, has become quite popular in the building sector because of its sustainable, lightweight, and energy-efficient qualities. The autoclave AAC plant, which streamlines the manufacturing process through a number of clearly defined processes, is essential to the production of AAC. The parts, functions, advantages, and uses of autoclave AAC plants are examined in this article.

What is an AAC ?

An autoclave Autoclaved aerated concrete blocks and panels are produced at specialist facilities called AAC plants. After the AAC products are created, the facility cures them in a high-pressure steam chamber called an autoclave. The blocks' strength and durability are increased by this curing process, which qualifies them for a range of building uses.

Autoclaved Aerated Concrete (AAC) is a green, precast building material that has been used globally for over 70 years. It is widely adopted in residential, commercial, and industrial construction due to its superior properties. As a well-established and eco-friendly alternative to conventional building materials, AAC has rapidly gained market share worldwide.

Made from natural raw materials such as sand (or fly ash), cement, lime, gypsum, aluminum powder, and water, AAC undergoes a unique aeration process, resulting in a lightweight yet durable material. This innovative composition provides excellent insulation, structural integrity, and fire resistance in a single product, making it a sustainable choice for modern construction.

Technical Specification

Production Process in an Autoclave AAC Plant

• Raw Material Preparation :- Preparing raw materials including fly ash, cement, lime, gypsum, and aluminum powder is the initial step. Until they are required for mixing, these ingredients are kept in tanks or silos.
• Mixing:- In this step, a mixing device is used to blend the prepared raw components. Air bubbles are produced when the aluminum powder combines with water and calcium hydroxide to form hydrogen gas. The lightweight slurry produced by this reaction has the capacity to greatly expand.
• Casting :- After being well combined, a casting machine is used to pour the slurry into molds. The slurry is formed into blocks or panels by the molds, which will subsequently cure.
• Pre-curing :- After casting, the mixture undergoes a pre-curing process where it sets partially before being cut into individual blocks or panels.
• Cutting :- The set mixture is then cut into specified dimensions using cutting machines. This step is essential for creating uniform blocks that meet construction standards.
• Curing in Autoclave:- The cut blocks are transferred to an autoclave where they are cured under high pressure (800 to 1,200 kPa) and temperature (up to 190 °C) for approximately 12 hours. This steam curing process solidifies the material and enhances its strength through chemical reactions between silica and calcium hydroxide.
• Storage and Distribution:- After curing, the finished AAC blocks are removed from the autoclave, inspected for quality assurance, and stored for distribution to construction sites.
