Autoclaved aerated concrete (AAC) is a lightweight precast aerated concrete building material suitable for the production of concrete wall units A concrete masonry unit (CMU) as blocks. Autoclaved Aerated Concrete (AAC) products contain quartz sand, lime gypsum, lime, cement, water, and aluminum powder, and can be processed in a hot and pressed autoclave. Mixing concrete as a foaming agent with cement and other materials can greatly reduce its density after this treatment without reducing its strength. Autoclaved aerated concrete (AAC) is a unique product that you cannot make on your own.
Without additives, you can put it in a wet mix and make AAC. As we usually know, it is a completely separate product from concrete. Don’t fall. Like CMU, they are often used to make small-sized precast concrete components, for example. Cement blocks and similar elements. This would be useful to know especially if you’re searching for a property to buy and you’ll know what material would be good for your property.
Aluminum reacts corrosively with cement and creates gas in the mixture. These bubbles make the final product lighter. As the name suggests, part of this process is that the finished wet product must be autoclaved. An autoclave is a low-temperature furnace that can add moisture and pressure to the environment. When the autoclave is closed, the heat, moisture, and pressure will bake the block or other pre-formed shape, causing a chemical reaction that creates bubbles.
AAC has many interesting and valuable features. First of all, it is lightweight concrete. Second, it can be cut and worked with hand tools. Both of these features allow for quick on-site construction methods. Concrete additives Malaysia is important.
Made from ground cement, limed gypsum, slaked lime, and sand in a large to very fine ball mill. In some places fly ash is also an ingredient. Then the aluminum powder is added, which produces hydrogen gas. The gas produces small bubbles. The bubbles eventually produce material of relatively low density. usually 500 to 700kg / m3.
