AAC Aluminium Powder for Making AAC Block

What are the raw materials of aerated concrete blocks?   1. Basic ingredientsThe basic ingredients of aerated concrete include calcium materials and siliceous materials. Calcium materials are materials with calcium oxide (CaO) as the main component, such as cement, lime, water-quenched slag, volcanic ash, etc. Siliceous materials are materials with silicon dioxide (SiO2) as the main component, such as silica, sand, fly ash, tailings powder, etc.During the production process of aerated concrete equipment, there are certain technical requirements for the chemical composition, physical properties and fineness of the above basic ingredients to ensure the quality of the product.2. Gas-generating materials and bubble stabilizersGas-generating materials can react with certain substances in hot alkaline slurry to produce gas. In principle, some metal powders (such as aluminum, zinc) or chemicals (such as hydrogen peroxide, bleaching powder, etc.) can be used as gas-generating materials, b…
