AAC blocks,a unique and excellent type of building materials due to its super heat, fire and sound resistance.Its main raw material include quicklime,sand,cement,gypsum water and foam stabilizer. The chemical reaction due to the aluminum paste provides AAC its distinct porous structure, lightness, and insulation properties, completely different compared to other lightweight concrete materials. Generally,the raw material play an important role on AAC Blocks manufacture.Just follow me,giving you a clear impression on the raw material.
1.quicklime:providing CaO,then reaction with Sio2 and AL203,producing hydrated calcium silicates and hydrated calcium aluminate,in order to guarantee the product hardness.Quicklime also provides basicity which makes the aluminum liberate the gas.At the same time,with the heat released during hydration reaction, the product is hardened.
2.sand:Reacting with the calcareous material, produce hydration products, increasing the strength of the product.Moreover, sand can be used as framework, reducing the shrinkage of concrete products.
3.cement:the main role of cement is to ensure that the pouring stability, accelerated hardening and plastic strength.
①．inhibiting early cement hydration;
②．extending the lime digestion time and decreasing the final digestion temperature;
③．reaction with aluminum to liberate gas;
④．improving the strength and reducing the shrinkage.
5.water:ensure slurry stirred evenly and poured into mould smoothly
6.foam stabilizer :foam stability refers to the role with a solid foam surfactants.
